Hey Fidelity, how can I remember to invest every month?
- [00:36]
Fidelity Representative
With the Fidelity app, you can choose a schedule and set up recurring investments in stocks and ETFs.
- [00:43]
Dr. Sheila Blumberg
Oh, that sounds easier than I thought.
- [00:45]
Fidelity Representative
You got this?
- [00:46]
ALIE Ward
Yeah, I do.
- [00:48]
Dr. Sheila Blumberg
Now where did I put my keys?

Fidelity Representative
You will find them where you left them. Investing involves risk, including risk of loss. Fidelity Brokerage Services, LLC Member NYSE SIPC oh hey, it's that guy who watched your stuff at the library so you could go to the bathroom ALIE Ward and this is Ologies, and the lifeblood of the show is asking smart people sometimes not smart questions. So let's take a trip through your vascular system for phlebology, which you will learn in a few moments is not a good name for the episode because it does not totally encompass what this ologist does. So we had to figure something else out. And this guest is a vascular surgeon, and from what I understand, that is a very difficult job and vascular surgeons have been called the surgeon's surgeon. So if you're a surgeon who can impress surgeons, I'm going to want to come to your workplace and ask you all about it. So this doctor is a Clinical Associate professor of Vascular Surgery at NYU Langone Hospital in Brooklyn, where she did her fellowship and residency after getting her MD from Boston University and has said that what inspired her was having grown up in Kenya, where she saw access to high quality surgical care not readily accessible. So helping people has always been important to her and she's very good at it. So she's been on my list to help us learn about our circulation and we're going to get there in a minute. But first, thank you to all the patrons who submitted great questions for this ahead of time and you can join that@patreon.com Ologies it costs like a dollar. Thank you to everyone out there for wearing ologies merch from ologiesmerch.com and finding each other in the wild. And of course, thank you to everyone who leaves reviews which help the show stay pretty cozy at the top of the science charts, such as this one. This was left by Fisker4, who wrote Ologies has quickly become my go to podcast for every activity from baking to drawing to postponing a spiraling mental breakdown while I focus intently on Centipede facts. And I gotta say, Fisker 4, that's a hell of a review to leave right as we splash down into an episode about blood tunnels, but I think everyone's gonna like it nonetheless. This is a great one. Also, reviewer, save spiders. I see you. And yes, we have an arachnology episode in the works. Also, if anyone's looking for kid friendly episodes, we have Smallgies in its own feed, which is linked in the show notes. It's great for car trips with the kids. Okay, let's get into this episode. Get your knitting, fire up the lawnmower, put your feet up for everything from vaping and vein health, why you can get a prescription for new socks, scary airplane blood clots, teenage movie tropes that are true, using science for cinema, how to tie a tourniquet in a pinch, spider veins, arterial health, atherosclerosis, stents. What is an aneurysm and how not to have one. Covid and clotting. And why your leg is asleep right now. With NYU Lanone vascular. Vascular surgeon, phlebologist, as well as surgical angiologist and General Medical Hero, Dr. Sheila Blumberge.

Dr. Sheila Blumberg
Yeah, if you were doing I do do karaoke.
- [03:52]
ALIE Ward
Do you really?
- [03:53]
Dr. Sheila Blumberg
I used to. What's your go to? I had a good voice. I would try to do Aretha Franklin and tear the house down, but the less I sing, the better. The less I get Good. So I can't destroy her songs anymore.
- [04:08]
ALIE Ward
I bet you're still so good at it. If you could do Aretha Franklin one time. I feel like you're going to destroy it.
- [04:14]
Dr. Sheila Blumberg
Sheila Blumberg. She. Her. Hers.
- [04:17]
ALIE Ward
I've been wanting to talk to you for so long. This is very exciting. And would you say that lebology. Is there an ology for this that you would.
- [04:28]
Dr. Sheila Blumberg
Phlebology. Phlebology, if that's specific for vein zoning. But then vascular also includes arteries, so that would, I guess arteriology. But that's why we just say peripheral vascular.
- [04:39]
Fidelity Representative
Okay, so vasculology has been used one time, but some countries refer to the study of blood vessels as angiology, meaning vessel in Greek. But angiology sometimes deals with the lymphatic system, which we don't get into to. And angiologists are not always surgeons like Dr. Blumberg. But since she is generously letting me ask her a smart person, not smart questions and giving Us a lesson in all things blood vessels. We're going to go with that.
- [05:03]
ALIE Ward
I mean, the first question I'm sure a lot of people don't know, including myself. Veins, arteries, capillaries, what's going where?
- [05:13]
Dr. Sheila Blumberg
Okay, so those are all different sizes, first of all, decides whether it's a vein or a capillary. And then arteries are different pipes, so they're all pipes. Okay, so I'm a fancy plumber. And so arteries are the main way blood gets away from the heart. Okay, Those are the pipes that take blood away. Veins bring blood back to the heart.
- [05:36]
Fidelity Representative
So arteries go away. A veins think v Valentine heart. And if the blood is leaving the heart going away via artery, it's ready for the journey with a full tank of gas. In this case, the gas is oxygen. Now veins are heading back to the valentine's heart on empty and they're returning home to the lungs for a resupply of oxygen. And then into the heart and out through. What are they going out through? Arteries. Nice sexy arteries carrying that oxygen rich blood are typically bigger than veins, veins typically smaller.
- [06:12]
Dr. Sheila Blumberg
Smaller still though, capillary bed is within the tissue and that's where veins and arteries meet and sort of form a web at a very microscopic level. So we're talking microns. And that's where the exchange of oxygen happens at the level of the tissue. And so the arteries come into, let's say your kidney and then go to the capillary bed, become smaller from arteries to arterioles, and then capillaries, and then the capillaries exchange into venules on the other end and then the venules become veins. So the veins are the larger parts of things and that brings the blood back to the heart. And so that's your circulatory system.
- [06:52]
Fidelity Representative
So arteries, arterioles, capillaries, venules and veins, they're all vessels or tubes that circulate blood. Now from biggest to smallest pipes we got small venules branch toward the full size veins as they come closer to your heart. Veins have thinner walls. They're typically closer to the surface of the skin than arteries. And arteries are located deeper in the muscles. And arteries have thicker wal. So oxygenated blood leaves the heart via the arteries. Artery literally means to keep air. It's kind of like a train system that leads to major stops in the organs and the tissues of your body. And then that goes down roads into smaller arterials which go into teeny capillaries which are like little trails to the tissues. And capillaries are around One tenth the width of a human hair. So tiny. And while you're minding your own business, you're eating kettle corn, you casually have 40 billion capillaries. You're magic. Can you believe that? 40 billion you have that. I hope you flirt using that fact.
- [07:57]
ALIE Ward
Are there capillaries that are so small, they're like single file. In terms of blood cells, how small do they get?
- [08:03]
Dr. Sheila Blumberg
They have to be, because at that level, in order to exchange oxygen between the tissue, oxygen is just a molecule. It's got to be able to transfer itself across the bed of the cell layer to get to whichever organ it's perfusing. So there are almost less than a cell layer thick that level. Yeah. So extremely, extremely small. Not visible to the human eye without a microscope.
- [08:27]
Fidelity Representative
So it's been estimated that the human circulatory system would stretch out to be over 95,000 kilometers in order to pump more than 7,500 liters of your blood every day. By the way, that's 60,000 miles and 2,000 gallons.
- [08:43]
Dr. Sheila Blumberg
America to exchange it that quickly. Every second that we breathe and get blood through and the rate at which it's flowing, it has to happen just like that. So it's miraculous, in a way.
- [08:55]
ALIE Ward
Do our veins and arteries, do they get less elastic or less robust or. I guess hardening of the arteries is a situation.
- [09:05]
Dr. Sheila Blumberg
Yeah.
- [09:05]
ALIE Ward
What happens to us as we age? Do we start off with amazing veins and arteries, and then they get kind of shittier? What happens?
- [09:13]
Dr. Sheila Blumberg
Well, yes, I think the aging process, unfortunately for arteries, they tend to become harder. And there's obviously lifestyle and environmental things that we can do to make that worse or at least better. And so things like smoking and exposure to smoke and diabetes in general, those are the major factors in our environment and our lifestyle choices that end up hardening the arteries. And so you get plaque formation and then calcium deposits. And you can really see the calcium on imaging now, which they are doing more routinely for coronary arteries in the heart, to see what level of disease you have, you can scan and you can literally see the whiteness of the calcium that's deposited. So they get them harder. That's not good, because you want arteries and veins function well when they're softer, more compliant. Right. So they can squeeze and open as the heart beats and relaxes. The hardness, let's say, of the arteries is disease. So that's unfortunate. And a lot of that's not reversible once it happens.
- [10:20]
ALIE Ward
Ouch. What is the calcium deposits, where are those coming from?
- [10:25]
Dr. Sheila Blumberg
They're coming from the bloodstream, essentially. Right. So most of it happens over time. And the exposure to things like smoking, per se, makes that layer in between the inner layer and the outer layer thicker, and so it essentially deposits in there, and the effect is calcification. Yeah.
- [10:45]
Fidelity Representative
So I'm so sorry. I'm sorry. But smoking can swell those inner walls, choking the flow and making it easier to collect plaque, which contains cholesterol, cellular waste, clotting stuff called fibrin and calcium that can cause atherosclerosis, which is a thickening or the hardening of the arteries. But again, since this episode would have been easier to name phlebology, but phlebology is only about veins. Let's get more into it.
- [11:12]
ALIE Ward
What about veins and arteries? Do they have different properties in terms of their structure?
- [11:18]
Dr. Sheila Blumberg
Yeah, absolutely. So veins, at any point in time, 75% of your blood is in your veins.
- [11:24]
ALIE Ward
Oh, okay.
- [11:25]
Dr. Sheila Blumberg
The 25% is your arteries. So veins have to have a high capacitance. They have to be able to hold that much volume in any amount of time. So they're much more compliant, they're much more relaxed. And in order to get the blood back from your foot right back up to your heart, the way they do that is in a couple of mechanisms. They have valves on the inside. Arteries do not have valves. Valves are kind of like gates. They open, they let the blood go up, and they're supposed to shut tight so it doesn't drop back down. And so as blood goes up the column, it doesn't return distally. Distally, meaning back to the foot. What else happens is when we breathe, that also changes the pressure gradient in the veins. So that also moves the blood up. So veins have to be compliant because part of their activity is by breathing. So every time you breathe, you change the pressure in your chest that allows blood to come through and come up.
- [12:21]
Fidelity Representative
However, arteries.
- [12:23]
Dr. Sheila Blumberg
So arteries are not based on that, they're based on your heart. Right. Because that's where their blood's coming from. So they have to be strong enough to take that pressure. So, like, for example, if you're exercising, right, and you're fairly young, your pressure can go up to 200 millimeters of mercury. Right. That's normal when we're exerting ourselves. And so arteries have to be tough enough to take that amount of blood pressure. So they're much stronger vessels in general, so they're thicker, more muscular. And so when every time the heart beats, pumps blood through, so they don't need valves or anything like that. And in fact, valves would be a problem in artery because they just got to get the blood down across to all of our organs, meeting a lot of resistance. So the arteries have to be strong enough to do that, and the heart provides that pumping action forward. So very different.
- [13:14]
Fidelity Representative
And that upper number of your blood pressure is the force that your heart is beating that blood out or down to your organs. And the bottom number represents the pressure when things relax in between the beats.
- [13:26]
ALIE Ward
You don't faint at the sight of blood, I'm guessing.
- [13:29]
Dr. Sheila Blumberg
No, no, that's been from a young age, so I'm in the right business. Yeah.
- [13:34]
ALIE Ward
When you were going through med school, was there a really big divide in terms of, like, who could deal with a lot of blood and who was like, you know what? I'm really going to be more of.
- [13:43]
Dr. Sheila Blumberg
An outside doctor, more a radiologist or something? No. I think most people who go into med have a capacity to deal with injury and or blood. So I don't think that's very common. I've seen it in laypeople who are not in the medical field so far, but I think what sort of sorts people out is what kind of fluids they can tolerate. So it's not just blood. I think blood is pure, it's clean, it's sterile, it's red. It's pretty. I like red. But some people like phlegm, forget it. Stool, forget it. So, you know, there's some things that everyone can tolerate. So I wouldn't do colorectal surgery because that's not for me. So I prefer blood. And so I think that's what sorts people out is, what fluid you can tolerate. Not necessarily an aversion to blood so.
- [14:32]
ALIE Ward
Much do you have to deal with that in your patients? Let's say if someone needs a blood draw, I know for me, I have to look away. And I was getting a blood draw once and I looked away. I just averted my eyes and I realized I was staring right into a reflective surface. And so I accidentally was watching at the same time. But I've fainted, just cutting my finger. And I don't know why it happens because I think my brain is like, you're going to die. But do you see that in your patients at all? Anyone just keeling over?
- [15:02]
Dr. Sheila Blumberg
Well, especially the blood draws. So even now we have to be very good about making sure most people are seated just in case they do pass out. They're already in a reclining position and we can sort of keep them safe from themselves. But yeah, it does happen. That's not uncommon, actually.
- [15:17]
Fidelity Representative
So we chatted with Dr. Joy Reidenberg, who's a functional morphologist who does whale necropsies. And the first time she witnessed a veterinary surgery, she was so excited. But then she straight up fainted in the room with all these surgeons. And she explained that she had what's called a vasovagal reaction, which is an autonomic discharge of your nervous system that no one can predict is going to happen. And when that vagus nerve is stimulated, it causes a sudden drop in your heart rate and also maybe the dilation of blood vessels to your legs, which causes blood to pool there away from your brain, causing you to pass out. And it can happen from standing too long or heat exposure, stress, the sight of blood in an anesthetized animal. And In April of 2020, when the pandemic was very fresh and people were having things like hobbies, I tried whittling, and within the first few minutes of attempting to craft a sp, I cut my finger and I fainted into the kitchen sink.
- [16:20]
ALIE Ward
So what about when you're watching movies and you see a pool of blood? Are you ever like, that's not oxygenated? That is too much for what they hit?
- [16:31]
Dr. Sheila Blumberg
My commentary about movie blood is none of it looks really good.
- [16:35]
ALIE Ward
Why is that?
- [16:37]
Dr. Sheila Blumberg
I don't know what they use. And I heard they some of use paste of some sort. I can't think of which movie had really good. Maybe like Kill Bill, like, Quentin Tarantino has good blood, but the rest of them it's. And so I always, like, look at the characteristics of it. And so I'm like, that's so fake. Like, so you don't. I don't particularly get gory about those kinds of things because it doesn't look realistic.
- [16:59]
ALIE Ward
Is it the viscosity or the color?
- [17:02]
Dr. Sheila Blumberg
Both.
- [17:02]
ALIE Ward
Okay.
- [17:02]
Dr. Sheila Blumberg
Yeah. So the only thing that looks accurate most of the time is old dried blood. Like, if it's an old crime scene, that looks more realistic because it's congealed at that point. Right. So I think the fresh blood of when they cut people and they're sort of like spurting, I'm like, really? No, I don't.
- [17:21]
Fidelity Representative
She's not wrong. I researched this for way too long. And According to a 2022 slash film article titled Quentin Tarantino only wanted the best blood for Kill Bill special effects, it says it's really difficult to recreate blood digitally, and Tarantino prefers practical, real life, goopy effects. He also told a Time magazine reporter that, quote, I'm really particular about the blood. So we're using a mixture depending on the scenes. I don't want horror movie blood, all right? I want samurai blood. He says, you can't pour this raspberry pancake syrup on a sword and have it look good. You have to have this special kind of blood that you only see in samurai movies. Quote. So that's his take on it. And in yet Another article, a 2015 Vulture piece, there will be lots of blood. One of his producers divulged that Tarantino films require a separate blood budget and blood of such a specific range of hues that no other filmmaker is allowed to use it. And this range of bloods, plural, are under the label Tarantino Reds by the special effects house that furnishes his custom supply. He has a custom blood supplier. I hope this is a lesson. People make art, make science, make stuff. We're only here for a little bit. Life is short. Make stuff. Also, I was having a discussion with my favorite cheesemonger today. That French horror director Alexandre Aha has superb blood, and I trust them. But back to Tarantino. Another one of his producers has described the director's blood use as different and balletic in the way that it moves and squirts and gushes.
- [18:55]
ALIE Ward
Does that happen? Because I always feel like, you hear if you hit an artery, you're screwed. Veins are less of a problem. Is that true or is that complete nonsense?
- [19:07]
Dr. Sheila Blumberg
Well, that's to do with the pressure in the system. So artery is a high pressure, right? So when you cut an artery, the pressure at which it's coming out at you is high, so you're going to lose more blood quickly. Veins are low pressure systems, so if you cut a vein and you bleed, it's going to be sort of a slow kind of ooze and more controllable. And the second thing is, because veins, like I told you, are very soft and compressible, you're more likely to be able to control it just with pressure alone. You can cold pressure in arteries and get. Get pretty decent control as well. But that becomes the other part of it. Depending on which part of the body it is, you may not be able to compress it properly. And that's why it can be more life threatening. Obviously, if you. If you injure an arterial injury versus a venous injury. Yeah.
- [19:52]
ALIE Ward
So that's not flim flam.
- [19:53]
Dr. Sheila Blumberg
It's not flim flam.
- [19:55]
Fidelity Representative
Okay. And remember, arteries tend to be deeper in the muscle, so harder to compress. So imagine trying to stop the flow of a garden hose under a tarpon, which is like a venous injury versus crimping a fire hose under a mattress. Arterial. Now, this is an exaggeration, but you get it.
- [20:12]
ALIE Ward
What about your work? What is a lot of your practice looking at? What is the, what's your day like?
- [20:19]
Dr. Sheila Blumberg
My day is. And this is why vascular surgery is intriguing. It's varied. I do a very large venous practice, so that's a lot of varicose veins and venous ulcers and those kinds of patients. And then the other side of it with arterial disease, which is more sort of limb threatening problems. Right. So you have peripheral arterial disease where they're not getting enough blood flow to their extremity, most commonly to the foot. And this is why diabetics suffer from a lot of this. And then obviously, like I mentioned, smokers as well. And those patients who are at risk of limb loss, those are the ones who obviously I get involved in and try to revascularize them, try to improve the blood flow to that area. For the venous patients, it's definitely not a limb threatening problem, but it's. It's definitely a lifestyle kind of issue. Right. Because people's legs do not function well if they have a lot of venous insufficiency where the veins and the valves have become destroyed for whatever reason. We call them incompetent now. And they aren't able to get the blood out of the leg fast enough. They can start off with things such as swelling to begin with and then progress to skin changes where they start darkening their skin because the blood's just pooling at the ankles. And then the worst case scenario for a lot of those patients is getting skin ulcers at the ankle because their skin's been damaged over time. So that is a spectrum of disease that we see in the venous space. And each person's sort of treated a little bit differently with that. So every day is a little bit different. Every patient's a little bit different. Every patient needs something a little different from the last patient.
- [21:52]
ALIE Ward
And when it comes to surgery, if you're doing surgery, especially on an artery which is high pressure, that I just learned that are you having to clamp.
- [22:00]
Fidelity Representative
Them off at either end?
- [22:01]
ALIE Ward
How do you stop someone from just bleeding out if you cut into that thing?
- [22:05]
Dr. Sheila Blumberg
Right. So typically we have control. So vascular surgeons, we love getting control of things. So it's usually above and below where the hole is, regardless of where that is in the body. And once you have control of it, you can actually take a beat and just repair what you need. To. And there's various ways to do that. Whether or not it's patching it with a piece of vein of the patient, you can use that. You can take their vein as a graft and use that to replace the hole in the artery and. Or repair it just with sutures alone. Put some stitches in it, and that should be enough to control it. So as long as you can get control above and below the injury, most things can be fixed.
- [22:48]
ALIE Ward
And then does blood find its way around other places? Is it like a detour on the.
- [22:52]
Dr. Sheila Blumberg
Highway while you have it clamped down? Yeah. Yes, it can, depending on where the injury is. So, for example, in the leg, commonly if people get shot in the leg in trauma situations, and it happens to be in an artery in the thigh, which is your femoral artery, you can repair that. There's another deep femoral artery that they can get blood supply around it. But you are having some time of ischemia. There's some time you're not getting any blood flow, which is why the repair has to be somewhat expeditious, because after, you know, in the leg, it can probably tolerate at least four or five hours maybe of ischemia before you start to get. Now death and muscle death and tissue death. So that has to be taken into consideration for sure.
- [23:32]
Fidelity Representative
And ischemia is the term for not getting enough arterial blood because you've been shot in the leg, in the femoral artery, and thus not getting enough oxygen to those parts, which can lead to very unhappy tissues and muscles when you're.
- [23:49]
ALIE Ward
Doing surgery and they say, oh, we've got to get up to, say, a valve in the heart. We're just going to pop into the femoral artery in your crotch. I'm like, how do you get that far? There's got to be twists and turns, right?
- [24:03]
Fidelity Representative
How do you do it?
- [24:04]
Dr. Sheila Blumberg
How? Well, thankfully, at least, the first person who designed was the Selinger technique of putting in needle and a wire and a catheter into a vessel. That principle has been taken to make larger and bigger sheets and catheters and just devices basically, that can transfer catheters and balloons and even valves directly into the heart. So it's a straight shot because, like I said, it's a pipe like any other pipe, and you can go through the pipe with any sort of tool as long as it's a decent size and there's not a lot of clot or anything that would be obstructing that. Medical advancement has been probably one of the most remarkable things that we have done in the last 60 years or so is being able to do a lot of things minimally, invasively, because there's a direct route. So that's great. The anatomy is very consistent and well described.
- [24:59]
Fidelity Representative
So. Swedish radiologist Sven Ivar Seldinger debuted this technique in 1953, which uses a hollow needle to get under the skin, in which you can insert a thin wire as a guide through your blood plumbing, which then guides a catheter to, quote, previously unreachable vascular areas of the body, and then you withdraw the guide wire. What a revolution, right? But no, he wasn't carried on people's shoulders through the town square. No one threw confetti at him or gave him candy or named a day in his honor. It wasn't until 30 years later that the field of angiography, which is mapping the circulatory system, gave him the credit that he deserved, but still worth doing, even if it seems like people don't notice while you're alive. But whatever your hobby or your passion, it doesn't have to involve vascular surgery. Even though it's pretty tight, it's so.
- [25:48]
ALIE Ward
Bonkers that that can even happen. And when it comes to history and your history, how did. Of all of the winding, twisting roads one could take, how did you end up in this field?
- [26:00]
Dr. Sheila Blumberg
I chose vascular surgery. And it takes a while to become a vascular surgeon in terms of the route from medical school to surgery training. At the time, as I'm getting older now, there was an indirect route from medical school, direct vascular surgery. So I actually did general surgery first, which is operating on every part of the body. And then I, while I was doing that, I had to make a decision about which specialty I was going to do within surgery. So I think that part of my decision was based on the fact that vascular surgery is very delicate. We deal with very. Also sick patients. And the actual procedures themselves require sort of a very gentle hand, which I think I have, and I enjoy that delicacy of operating. And also we have. There's a lot of variety as well. So, like I said, one day I'll be doing veins, one day I'll be doing arteries. And then I operate on various parts in the body, in the neck, in the leg, in the chest, in the abdomen. So there's a lot of places where you have to be sort of facile with what's there and how to get to some areas, because arteries and veins aren't just sitting waiting for you. You gotta find them. And so that's always been very interesting to me, and I Just love that kind of surgery. So that's how I ended up picking this specific specialty of all the other specialties. And like I mentioned before, blood is a very nice looking fluid. The other ones I don't have a lot of affinity for, so I was happy to pick vascular.
- [27:29]
ALIE Ward
Does blood look different when it's leaving the heart versus when it's on its return trip?
- [27:33]
Dr. Sheila Blumberg
Absolutely. Yeah. When it leaves the heart now, it's been freshly oxygenated, so it's nice and bright red. So arterial blood looks really red, like scarlet. And then venous blood when it's returning is much darker because now it's quote unquote deoxygenated. There's not a lot of oxygen in it anymore and so it's darker. Kind of violations like a color that we can describe it.
- [27:56]
Fidelity Representative
So arterial oxygen rich blood is bright red and venous blood is a little more purplish. Arterial is the color of bright ketchup. And venous blood looks a little more like a plum sauce or the color of raspberry jam. I'm trying to make this appetizing so.

You can tell if you puncture a vein or puncture an artery sort of immediately. In a healthy person, you can tell whether you're in an artery or vein just by the quality of the blood you're looking at.
- [28:22]
ALIE Ward
What about when we look at veins and they look blue from.
- [28:27]
Dr. Sheila Blumberg
They should, yeah, yeah, they should look blue.
- [28:29]
ALIE Ward
Why are they looking blue?
- [28:30]
Dr. Sheila Blumberg
Because the blood is dark now. So they should look blue in a healthy vein. That's its right color. Yeah.
- [28:36]
ALIE Ward
I remember hearing myths about that, that your blood is blue until it hits air.
- [28:42]
Dr. Sheila Blumberg
I think they're probably referring to the oxygenation situation and the arteries being more red blood because it is oxygenated blood.
- [28:49]
ALIE Ward
Yeah, I mean, I heard all kinds of stuff when I was a kid. I mean, I think we thought unicorns were real. So you know what I mean?
- [28:54]
Dr. Sheila Blumberg
So kind of.
- [28:56]
ALIE Ward
And what happens when you blush or when you're embarrassed or when you get hives? Is that blood just flooding capillaries?
- [29:07]
Dr. Sheila Blumberg
Yeah, capillaries and very small arteries and veins in the face, really, and they just dilate. So it's a parasympathetic response and a sympathetic response and you get huge vasodilation and then it bursts and then it goes away. So it's kind of like a big flash. It's mysterious, really, why it's so specific to certain areas that we still don't understand.
- [29:29]
Fidelity Representative
I did find a 2020 paper titled the Unique contribution of Blushing to the Development of social anxiety disorder symptom results from a longitudinal study, the methodology of which involved making kids perform a song in front of a parent and a stranger and then watching themselves back on video Before a researcher aimed an infrared temperature gauge at their cheeks to determine if they would be prone to later developing what's known as sad social anxiety disorder. Why blushing happens, I don't know. But what's valuable about this study is that it will be cited often in those kids future therapy appointments. Someone's making money off that.
- [30:08]
ALIE Ward
Do you ever think about that stuff? Are you aware of your own blood day to day?
- [30:12]
Dr. Sheila Blumberg
No, thank God. Like, I don't. I don't. I don't really think about it that much, quite frankly, at least on my own day to day. What I do think about is venous health in a way, not necessarily the blood itself, but for example, like, I wear compression stockings at work because I don't want to have swollen feet, et cetera, because it's more common in jobs where you're standing all the time. The second I knew about that in residency, I started wearing them, like right away. I was like, this is important. And I feel like most more people should know that if they're in jobs where they stand all the time or when you get pregnant, you should wear compression stockings as much as you can. Yeah.
- [30:51]
ALIE Ward
What about on airplanes?
- [30:52]
Dr. Sheila Blumberg
Absolutely, yeah.
- [30:53]
ALIE Ward
What's going on with that?
- [30:54]
Dr. Sheila Blumberg
So the gravity, which is sitting down with your legs that way, and then the pressure changes in the air are more likely to make blood pool at the ankle and you get swollen, especially for long flights. It's a game changer. So I tell everybody who listened to me to wear them on the plane all the time. But I think that's caught on. I feel like a lot of people are doing that now.
- [31:16]
ALIE Ward
You know, I have a friend who's a doctor who's also at nyu, Mike Natter, who got me a pair of compression socks and I should have packed it for my flight. But what about varicose veins? You said that you work on that.
- [31:27]
Dr. Sheila Blumberg
Yeah.
- [31:28]
ALIE Ward
How do those happen and are we treating them? We. As if I help treating them with lasers more. Do you have to go in there and pluck them out?
- [31:37]
Dr. Sheila Blumberg
Yeah. So I think that's another part in which we've had a lot of advancements of the last 30 or so varicose veins. And you'll hear a lot of terms used to describe it, like venous insufficiency, venous incompetence, varicose veins. But ultimately what it means is that that one part of the venous system is not doing its job correctly. And this is all in the lower extremity for the most part. So in the lower extremity, you have two systems of veins, two main ones. You have the deep veins, which live in the muscle. That's why we call them deep, because they're in the muscle layer. And those are the most important veins. They do about 90 plus percent of the work of getting the blood from your foot back up to your heart. They also have a secondary system of veins, which is a superficial vein. So the reason they're called superficial is because they're above the muscular layer and they're just surrounded by our skin and fat. But it's connected to the deep system. We call the connections between them sort of perforators. And together they're supposed to transfer the blood from your foot back up to your heart. What happens to a lot of people over time? About probably 20 million people in this country suffer from this. The superficial system becomes incompetent. And what that means is the valves in the inside of the superficial veins, they stop closing tight. So these are the gates that I described that open shut to let the blood go up. They become incompetent, they become weak, so they don't close as much supposed to. And so blood takes longer to get out of that superficial vein.
- [33:08]
Fidelity Representative
So what happens if there are venous blood traffic jams because the gates and the valves went wonky and they can't merge from the superficial veins to the deeper ones and then back to the heart for more oxygen.
- [33:21]
Dr. Sheila Blumberg
What happens over time? Your body's way of dealing with sort of, we call it this venous hypertension in the leg is to make varicose veins. So you'll see these large sort of bulging little varicose that come out of there. They're not supposed to be there. Your body made them to deal with the pressure in the system. And so that's a sign that you have quote, unquote, venous disease, right? And the treatment pretty much for thousands of years is you get rid of it somehow. Olden times, they used to have to strip it, right, which is basically make incisions in the groin and lower leg and then remove the vein entirely. And that would be it.
- [33:56]
ALIE Ward
What's my other option?
- [33:58]
Dr. Sheila Blumberg
And then now, thankfully, we have lasers, which is what you were describing before, which essentially do the same thing, but they do it through a catheter, again, like I told you, needle wire catheter through there, and then seals the vein from the Inside, which essentially shuts it down. So the technology is a lot better now. And that's kind of like an outpatient in the office. Procedure takes half an hour. Patients do well, we check on them probably a week later and they can return back to work the next day. So it's very, it's ambulatory and they're legs improve pretty remarkably quite quickly. So it's very rewarding. And this is the part I was talking about. It's in terms of lifestyle. They're able to walk further, do whatever they need to do. Less likely to get wounds in the future. But, you know, their data about that is still soft because we don't really follow them for 40 years to see what they're going to look like, unfortunately. But that's something that I think intuitively makes sense.
- [34:52]
ALIE Ward
Are varicose veins just a cosmetic concern or are those a concern in terms of your actual vein health that, like if you're making extra veins, you've got some issues down there we should, should solve anyway?
- [35:03]
Dr. Sheila Blumberg
Yeah, so I think there's two camps about that. There's certain patients who will start off with just varicose veins and may just stay like that for the next 40 years. Okay. They'll have probably some leg swelling, some heaviness, fatigue, and they can tolerate that. There's some patients who will start off with varicose veins and they'll end up. And I'll see them in their 60s and say, you know, this started when I was 30 and they told me it was just cosmetic. And now they have horrible wounds and all sorts of problems. And so question is, had we started to treat them in their 30s, would they have been this miserable in their 60s? And I think that I fall into that second camp of trying to make sure that Larry veins are as healthy as they can be throughout their lifetime. So it's really a conversation with the person that you're treating about what it is that they're trying to accomplish, what their life goals are, what their functional status is, what they want to be able to do. And that becomes more important to me than the other parts of it.
- [35:58]
ALIE Ward
Do compression socks help your veins with that too?
- [36:02]
Dr. Sheila Blumberg
So I think having compression is an assistive device. Right. Because it creates a higher pressure at the ankle so that the blood doesn't pull there. So even if you do have vein problems, that will help at least boost some of the flow out of the leg. So, yes, I think that they're important. I wear them like I told you, even though I don't have Venus disease. Because I just want to make sure that, that they're as healthy as they can be, you know.
- [36:26]
ALIE Ward
What about crossing your legs?
- [36:28]
Dr. Sheila Blumberg
Not bad actually. It's bad for your hips and apparently I have to stop doing that.
- [36:33]
ALIE Ward
I do it all the time. I'm doing it right now.
- [36:35]
Dr. Sheila Blumberg
Yeah. And the compressing blood flow. No, what that will do is mostly muscular and then nerve. It can pinch your nerve in your palpateal fossa and that can cause, you know, when you cross for too long, when you feel like your foot's numb and you can't feel it, that kind of thing. But not the blood flow will still be was fine.
- [36:51]
Fidelity Representative
So your foot falling asleep is not usually a blood issue, but it's a neurological one, the nerve.
- [36:56]
ALIE Ward
And you mentioned deep veins, deep vein thrombosis. Yeah, I feel terrified of it. I have a friend who went through it recently as well and luckily she's on the men but has to be on blood thinners. So when we hear about blood clots versus deep vein thrombosis. What's going on in there?
- [37:14]
Dr. Sheila Blumberg
Yeah, deep vein thrombosis is the part of venous disease that can be life threatening because a not insignificant number of people, around 600,000 people, die a year from a deep vein thrombosis. And the reason they die isn't from the clot itself, it's from the clot traveling to their heart because like I said, it's connected. And then once it goes into the heart and then into the lung arteries, it's called a pulmonary embolus. And that can kill you because if their heart has obstructed flow and it can't get blood out, you get a heart attack and then they die and it's a cause of sudden death.
- [37:49]
Fidelity Representative
And heads up. So DVT, or deep vein thrombosis, happens when a blood clot or a delightfully named thrombus forms in the deeper veins and usually a leg like at the side of those valves or gates. And symptoms can include swelling, pain, fluid retention, some discoloration and even fever. Now, if you have dvt, a doctor may put you on blood thinners to prevent that clot from detaching and just going on a walkabout to places you don't want it, like the lungs or the heart or your brain. As for Covid and clotting, a 2023 study, risk of thrombosis during and after SARS CoV2 infection, pathogenesis, diagnostic Approach and Management in the journal Hematology Reports says that coronavirus disease COVID 19 increases the risk of thromboembolytic events, especially in patients with severe infections requiring intensive care and cardiorespiratory support. And that COVID 19 patients with thromboembolitic complications have a higher risk of death. And if they survive, these complications are expected to negatively affect these patients quality of life. So Covid increases the risk of blood clots. And the worse your case of it, the more at risk you are for that. It also says that recent data show that the risk of thromboembolism remains high months after the infection. Now why is this happening? And there was Another study, a 2023 study, SARS CoV infection triggers pro atherogenic inflammatory responses in human coronary vessels. In the journal Nature. And it presented data that established that SARS CoV2 infects coronary vessels, inducing plaque inflammation that could trigger acute cardiovascular complications and increase the long term cardiovascular risk. So Covid ups your chance of clots and data show that it can infect coronary vessels. So how do you not get blood clots, clots and thrombosis? It's never a bad idea to avoid getting Covid. Remember to get your boosters. Don't be afraid to mask up, because a blood clot is scarier than a weird look from a stranger, in my opinion and experience. But other ways in general to prevent blood clots and deep vein thrombosis are to keep it moving. Move your BOD if you have the option.
- [40:04]
Dr. Sheila Blumberg
So I think it's important for people to know about it, and the ways to prevent it really are minimal. A lot of it can happen in a hospitalized setting where you're immobilized for a long time or you've had orthopedic surgery, et cetera. This is where compression becomes important. Moving is important also. If you have had a surgery or you have a family history of blood clots, then you may need to be on blood thinners to prevent that from happening. But it is something that is a serious problem, right? And can happen in an unrecognized fashion. It's still rare. We'll say that, like most people aren't going to have it. Like I said, 20 million people have superficial vein disease, but not a lot of people get dvts in general. But that's something that should be recognized more, I think, in general in public health, because the people who tend to do worse from it tend to be minorities, underrepresented minorities specifically, especially after childbirth in women. That's something that we've seen. I think even Serena Williams had one and had a second one, I think at her second pregnancy. And that wasn't recognized, but she knew what was happening and she had to tell the doctors, this happened to me last time. And so that's how when they recognized it and treated her appropriately. So it is something that should be announced widely. People should be concerned about what do you look for?
- [41:28]
Fidelity Representative
Dr. Blumberg explains.
- [41:30]
Dr. Sheila Blumberg
Typically it will start with some swelling and pain in the leg. And it's usually not both legs. It's usually just one leg that's asymmetrically for some reason, feels swollen. It's more painful. They should get checked out. It's a very simple test to look for it. It's an ultrasound that's cheap, effective, and highly diagnostic for that, if you get it.
- [41:50]
ALIE Ward
Do you find that especially with people who are going through childbirth, or is it a fact of certain people just not being listened to or more predisposed or. I imagine a combination of both.
- [42:05]
Dr. Sheila Blumberg
I think a combination of both. There are people who are hypercoagulable. Right. That's what we call them, their blood clots. For some reason, pregnancy by itself is a hypercoagulable state. So women who are pregnant can form more clots because that's kind of the coagulation pathway of carrying a child. So there's a heightened risk and assessment in those patients. And OBGYNs, I think, are very cognizant of that and do a good job of that. I think in our medical community, there are people whose pain and or concerns aren't addressed as they should be. And I think that's hopefully changing, especially as the workforce that takes care of them changes. Right. So if you're more aware that this happens to minorities and there are certain minority doctors, that helps to move that forward. And so I think that's improving. But it has been an issue historically.
- [42:59]
ALIE Ward
When it comes to getting the word out about venous health, too. In arterial health, what are things that you wish people knew before something becomes a problem?
- [43:09]
Dr. Sheila Blumberg
Yeah. So I think we'll start with arterial disease first. Just I'll say simply smoking is bad. It's always been bad. It's going to continue to be bad. And I don't think. And I know that now New York State has ads about people losing their fingers and their toes to. And there's quit smoking campaigns. And that's important because they've previously never addressed the fact that that's actually a risk factor of smoking. Is that. So I think that's one thing. If you can just not start smoking because it's extremely hard to quit. And we talk to patients about this all the time. Don't do that. The second thing is diabetes. That's then still today, now is the number one cause of amputations in this country after trauma. So if you're not an accident where you lose your leg, diabetes is the number one cause of you losing your limb in this country. And that's a big problem. So diabetes control, which also stems now from obesity.
- [44:08]
Fidelity Representative
So we've mentioned this in previous episodes as recently as last week, but some people object to the word obesity to refer to certain body compositions that could potentially impact health negatively. But it is the current medical terminology that doctors use. And while some doctors have overlooked actual causation of illnesses by wrongfully blaming body composition, most, like Dr. Bloomberg, are relying on years of research to keep us all living longer and healthier with fewer complications.
- [44:36]
Dr. Sheila Blumberg
So it all starts there. So those are the things. So health and wellness. I'm sort of an end stage doctor by the time you get to me. A lot of things have happened along the way that hopefully could have been reversed. So I think weight control, obesity management, diabetes management, smoking, those are sort of the pillars of arterial health and also venous health, because we'll now switch to veins.
- [45:02]
Fidelity Representative
Remember, veins return blood to your valentine.
- [45:05]
Dr. Sheila Blumberg
Heart function of veins is dependent on returning flow from a foot up to the heart. Weight plays a big role in that. If you're overweight, that's just a harder job for your veins to do. And that contributes to the development of the disease and also the outcomes after you start treating the disease. It's not just lasering everything. Right. Those are the things I wish people knew beforehand. And then also wearing compression socks if you stand for too long at any job, Because I see a lot of people, mostly women who did factory jobs, machinists, nurses, doctors. And they're all like, yeah, my legs have been killing me for years. And I think we used to have a fair once a year at NYU where we'd just give our compression socks and you could sign scripts for people just so that the workforce could have it, because we knew that this is. This is the thing. So that's important.
- [45:53]
ALIE Ward
I think you mentioned smoking, too. And I have been in New York for just this past week, and I'm from California, and I have walked through absolutely fogs of weed. And I feel like more people smoke, not just cigarettes, but just in general, people who don't smoke cigarettes or maybe smoking more weed and vaping. Do those have Any impact on your venous health?
- [46:14]
Fidelity Representative
You ready for this?
- [46:15]
Dr. Sheila Blumberg
Yeah. I think the data on vaping is that it's pretty much as bad as tobacco. And also the particulates in vaping may actually be worse, at least for lungs in general. But that's a different ballgame altogether. The marijuana smoke and the legalization of marijuana has actually opened up a huge can of worms, I think, for people regarding public health, because you'll have conversations where people think it's natural, me and Mother Nature, and therefore it's not going to harm them. But we don't have enough data on long term use of marijuana and how that affects the arterial system. I can say our suspicions from the early reports now are that it's quite damaging to your circulatory system. And unfortunately, with the widespread use, I think we're going to start seeing that in younger people who are consuming it at these high rates. And that's a big concern to me because I think this concept of it's a plant and if I smoke it, it's not tobacco, so it's not going to hurt me is a problem. There's other things that are natural that occur in a plant. Well, it's just heroin comes from a flower. That's not necessarily good for you. Now that it's legal, it can actually be studied. Right. And the natural population, natural studies will start to come out. And I'm not optimistic that it's going to be good news.
- [47:44]
Fidelity Representative
So let's stick to gummies, maybe.
- [47:46]
Dr. Sheila Blumberg
Yeah, if you need it. Yeah.
- [47:49]
Fidelity Representative
Okay. Smoking weed, definitely not without its bodily consequences from a vascular biology standpoint, sorry to say. And for more on this, you can see the 2019 paper, Harmful effects of Smoking Cannabis A Cerebrovascular and Neurological Perspective. And also news came out in 2022 that if you're an adult who has a bleeding stroke and you have enjoyed the ganja in the last month, you're twice as likely to die or have serious injury from that stroke. But it's really hard to determine what's caused by the smoking or the vaping factor. Right. So I did this deep dive on edibles, and you don't want to hear this, neither do I, but I have a responsibility to tell us that. A 2019 Annals of Internal Medicine paper, Acute Illness Associated with Cannabis Use by Route of Exposure, did find that according to the Colorado Behavioral Risk Factor Surveillance System, about half of THC users just smoke and about. About 4% just do edibles. And the rest are kind of a combo of both. But edible cannabis did account for more ER visits for acute psychiatric symptoms. So don't let your mom eat the whole brownie. And visits for cardiovascular symptoms. So that's concerning. Does it have to do with all the snacks you like to eat when you're cooked? Jury's still very much out, and more research needs to be done. And doctors and scientists still need more questions answered, as do you.

- [56:33]
Dr. Sheila Blumberg
So bruising is at the very superficial level of the skin where the I guess we can say capillaries slash veins burst just from injury. Right? So it's very localized. You're obviously going to see it more if you're pale. Some people are more prone to bruising because they have either some platelet dysfunction where they don't clot fast enough because if they're able to clot fast enough, it shouldn't bruise as much or shouldn't have as much spread of blood in that area. And so people who are prone to easy bruising, they should just have a simple blood test just to make sure they don't have an issue with clotting disorder or bleeding disorder.

Other factors that can cause easy bruising are taking medications like ibuprofen or Advil, Naproxen like Aleve, blood thinners, antidepressants, and antibiotics. Now another cause of easy bruising is not having died yet. And as we continue to age, our skin gets thinner and has less cushion for that blood tubing we've got. And I asked the Mayo Clinic how not to have purple legs, and it offered the following solutions. Use good lighting in your home. Have your vision tested. Arrange furniture and electrical cords so that they're not in your way when you walk. Avoid clutter. So doctors say lovingly, either check your meds or get your shit together.

I was getting a ton of bruises, and then I realized it was because I was eating too many baby aspirations. I'd get a headache and be like, ooh, baby aspirin's delicious. And then I was like, you're chilling. I have one more. And then I thought I had leukemia. Turned out I was just eating too many. What about circulation?

Are my hands and feet so Cold.

ALIE Ward
Is it poor circulation or is that just a myth? Dr. Casey asks.
- [58:17]
Dr. Sheila Blumberg
So the cold hands, cold feet. There's some people who have perfect circulation and have cold hands and cold feet, and they'll come in and there's not much we can do for them because there's no blockages. Right. There are some people who have a phenomenon called Raynaud's, where essentially they spasm. There are very, very tiny arteries in their hands and especially gets worse in the wintertime. What we recommend is just warming for those kinds of people because it's usually related to underlying rheumatologic problems that they may also have.
- [58:50]
Fidelity Representative
So with Raynaud's, your blood vessels may kind of slam shut. And my friend Mackenzie has this, and a few of her fingers can just suddenly turn white. I think it looks cool, but as an equestrian who's outside a lot, she's got to keep those fingies warm. But if you start to notice that you're just developing cold hands or feet and you haven't just moved to Canada, it could indicate a new issue, like peripheral artery disease, which is when plaques form in the arteries of your limbs, or something like an autoimmune disease like lupus or rheumatoid arthritis, or maybe a thyroid issue. And yes, we do have an episode on thyroids coming up. Also, in terms of chickening out on something, the origin of the phrase cold feet is hotly debated. But in 2005, Slate published the article, when did we get cold feet? The Germans had them first, which is accusatory, but it traces the popularization back to German soldiers apprehensions in getting killed in World War I. They were like, I can't get out of this trench. My feet are too cold. But centuries earlier, an Italian proverb involved being cold in the feet to mean being shoeless, to mean being broke, which then meant that a gambler was too belly up. So they backed out of a bet. Which, if you're broke, backing out sounds like a great idea. Like 10 out of 10 would bail ASAP. But if your actual feet and hands and nose are cold, and it's been like this for a while, that's kind of your brand. Docs say that it's healthy for your body to say, hey, I'm cold, cold. I'm just gonna hoard more blood in our organs, if that's cool. Because you can't put a beanie on your liver, babies.

Dr. Sheila Blumberg
It's Very, very rarely a limb threatening or digit threatening problem. But there are some people who just have peripherally cold hands and cold feet and my daughter is one of them. There's nothing to do about it. So it's.

Yeah, yeah. She's like freezing hands since the day she was born.

ALIE Ward
So Pockets. Yeah, a few people. Bjorn, Fred Berg, Miranda Panda, Sadie Vipand wanted to ask about hemophilia. What is it, what is it, in Bjorn's words, that hinders the blood from clotting or lack thereof.
- [60:54]
Dr. Sheila Blumberg
Yeah, that's taking me back to sort of med school. That's more in the hematologic sort of realm as opposed to circulation. And it's genetically inherited, at least the most famous one is from mothers to sons because it's on the X chromosome. So it tends to be more profound in boys because at least girls have 2x's whereas boy has 1x and 1y. So if they tend to present in boys because they're the ones who manifest it, whereas the girls will have protection from the second X and those are the ones who can't make that factor. And then they bleed. And I think one of the czar's sons had it, Nicholas back in the Russian Revolution and he was basically contained in a bubble as long as he can until the revolution and they killed his whole family and as well. But yeah, and that was passed from I think the Zarina's line with families. But yeah, so it's a coagulation pathway problem where one of the factors is missing and it's. Those are. Those are still quite rare in hemophiliacs.

Fidelity Representative
Okay. So this side quest of info dumping kind of warrants its own three part episode. So I'm just going to give you some broad strokes, if you will and move on. So there was this mysterious blood and bleeding disease among European royal families and it all traced back to a blood disorder transmitted to various European royals by Queen Victoria, who also went by the title Her Majesty Victoria by the grace of God of the United Kingdom of Great Britain and Ireland, Queen, Defender of the Faith, Empress of India. And yes, one of her descendants among royals was Alexei, the great grandson of Queen Victoria. And he was a chunk of a baby, 11 pounds of butterball baby. But he had this royal disease. It was found out when his umbilical cord bled for hours and hours. His royal family was freaked out, but they didn't disclose his health problems to the public. Now, over the course of his childhood, he nearly bled out externally or internally from events as slight as a bump to the leg or a nosebleed. And there was this peasant monk who came along named Rasputin. And he was said to have the powers to cure Alexei by just pushing aside doctor's care and healing him through hypnosis. This and spells and just riz in general. But medical historians are now like, it may have just helped that he told the doctors to stop giving him aspirin because the aspirin thinned his blood. Also, placebos, they don't not work. Science knows that. But sadly, Alexei's fate was sealed by execution in a cellar at age 13 during the February Revolution in 1917. Now the family's remains were discovered 90 years later. And finally, in 2009, the paper genotype analysis identifies the cause of the royal disease, revealed that the royal disease was hemophilia B, a blood clotting disorder which can be carried by females but can manifest in male descendants. Or it can just arise spontaneously in a family line, especially by mutations resulting from older dads spermies. But speaking of history and shady medical treatments, I do want to let you know that yes, bloodletting was a thing up until like the 1700s. And back in the day, barbers, they were the only ones with sharp tools in town. So they were tasked with all kinds of things like opening veins up and extracting teeth, applying leeches and setting bone fractures. They were the original med spas. Barbershop surgeons also cut hair and stuff. And that striped barber pole that you see outside modern day establishments. So legend has it that it descended from the shape of a basin of leeches at the top and the stick that patients would grip to encourage little suckers to do their business faster. Now others say that the red stripes are reminiscent of stained bloody strips of gauze they would hang outside to dry. Either way, next time you have any medical procedure done, be glad that you're not surrounded by stray beard hairs and a weirdo with a leech and that you have a nice person in a clean lab coat in front of you.
- [64:58]
ALIE Ward
When it comes to drawing blood. Yeah, a few people asked. Bulky Kibble says, when I'm getting blood drawn, I'm always told I have good veins. What does that actually mean? Bart Miller asked, why do phlebotomists always have a hard time finding my veins when it comes to bloodletting, why do some people don't do as well as others?
- [65:19]
Dr. Sheila Blumberg
Well, we're hopefully we're not bloodletting anybody anymore. Drawing blood, if you have good veins, it basically means that you've made everyone's job easier because you're plump veins and hydrated. And there's some when you put the tourniquet up in order to see the veins when they're drawing blood, some people's become more prominent than others. Depends on the state of hydration. Sometimes they dehydrate, et cetera and their veins are not visible or you can't touch them, you can't feel them when you touch them. That makes it more challenging. So people who have more prominent veins who may have, you know, know, probably thinner arms, et cetera, may be easier for us to get blood from. There's some people who for whatever reason, and it's usually most difficult in hospitalized patients who've had multiple blood draws or who need blood repeatedly at some point the vein's been touched and injured too many times that it can't be accessed. We call them quote unquote tough sticks. Like you can't find a good vein in there. Right. And most of those people, you want to try to find places where the skin is kind of the thinnest. So that's why a lot of people end up getting blood drawn in the. Not armpit, but here in the elbow pit. Of the elbow pit, the antecubital fossa is what we call it because it's probably the thinnest place where the veins come up to the skin at a level which most people can access.
- [66:39]
ALIE Ward
So you could make a phlebotomist day by hydrating a little if you're able to.
- [66:45]
Dr. Sheila Blumberg
Because sometimes they make you either fast for a blood test or something like that, depending on what it is. But ideally chug a bunch of water beforehand if you know you're a tough stick. That will help.
- [66:55]
ALIE Ward
I just love the idea of behind the scenes. Someone said, oh yeah, room 14. It's tough stick, man, tough stick. What about rolling veins? A ton of people asked about Gabrielle Heiss asked. She said fantastic about the topic. Excited for the topic. Why are some veins rollier? Is. I've never heard the term rolly veins.
- [67:15]
Dr. Sheila Blumberg
Yeah.
- [67:16]
Fidelity Representative
Also on the minds of Kay Lucas, Gabrielle Heiss, Death Nell, Kieran, Nehemiah Miles, Miranda Panda and first time question asker Bethany Scholz, who has rolly veins. And after seeing them via a nurse using a laser vein finder asked, why hasn't the goth clothing industry capitalized on vein pattern arm sleeved asking as a goth scientist, Bethany says Bethany, you're living in the future but you still have rolly veins. What's up with that?
- [67:41]
Dr. Sheila Blumberg
I think that's more Common in a way in very thin people. Because if you have less fat surrounding the vein, when you try to come after it, it just moves along the skin and you'll see it and it's like, oh, gosh. So you have to kind of stabilize it a little bit as you're trying to access it.
- [67:59]
ALIE Ward
You gotta chase them kind of going side to side.
- [68:02]
Dr. Sheila Blumberg
You have to kind of anticipate where it's going to go next and find it there. That's how I do it when the veins are rolling.

Sean Thomas Kane and R.P. bergman wanted to know, in Sean's words, is there a scientifically proven best practice for stopping nosebleeds? Is that a vein? Is that an artery?
- [68:21]
Dr. Sheila Blumberg
I mean, everything at some point is in her artery. But if you're having a nosebleed periodically, I mean, it's now head down and. And compress it even with like a tampon actually in the nose, and just let it hold pressure and it'll stop. But don't do this. Don't put the head back. You don't want to swallow the blood into your mouth. So head down. Put your head down and put some tampons in it. In one nostril, or if not a cotton ball, something that you can actually pull out easily. You don't want to get anything stuck there either.
- [68:51]
ALIE Ward
Head down. That's new information to me.

People have asked when they've donated blood. A vein collapsed?
- [69:14]
Dr. Sheila Blumberg
Yeah.
- [69:15]
Fidelity Representative
Is that.
- [69:15]
ALIE Ward
Does that have to do with the musculature?
- [69:17]
Dr. Sheila Blumberg
I think when they tell you your vein has collapsed, it basically for whatever reason, at the point at which they've drawn blood, but it's just kind of spasmed. Okay. So that's usually temporary.
- [69:28]
ALIE Ward
So don't freak out if your vein collapse.
- [69:30]
Dr. Sheila Blumberg
No, if it's still there.
- [69:31]
ALIE Ward
If someone's vein collapse, that's terrifying. And you're like, I need that.

Carlos de la Rosa and the Severinos asked about chemotherapy and vascular health. Is there a way to recover or heal the veins from the back of your hands or. Or anything during chemotherapy that you would recommend?
- [69:53]
Dr. Sheila Blumberg
So chemotherapy is tough because it really does destroy the cells within the lining of the veins, just because of the nature of the drugs that are going through, which is why they prefer to put it sort of directly through a port as opposed to peripherally. Although sometimes now they are using the veins in the arms directly for chemotherapy. Unfortunately, we don't have good reversal for that once that happens to it, or protection for that.
- [70:21]
Fidelity Representative
Where does the port go?
- [70:22]
Dr. Sheila Blumberg
It goes in the. Depending on where the. Either the subclavian vein, which is up here by the clavicle, or in the neck, IJ the internal jugular vein. And then the port sits at the chest level here because it's a clean area, less likely to get infected. And they can then access it repeatedly, especially if you need multiple rounds, as opposed to trying to access a vein multiple times in the hand, like we said, it can collapse, you can spasm. And then just tolerating the toxic chemicals, it's kind of easier because here's a direct shot into the heart. So they get the medication sort of straight, centrally, and then that gets distributed throughout the body.
- [71:01]
ALIE Ward
And you mentioned the jugular vein, which is the scariest sounding vein in the body, just because it's like going for the jugular. Why is that jugular so important?
- [71:10]
Dr. Sheila Blumberg
I think the jugular vein has sort of been mythologized as like the one that will murder you if you somebody cuts you. But I think what people forget is what was causing death wasn't the jugular vein, it was the carotid artery that was next to it. Okay. So when, you know, for example, in Quintino, when they cut somebody's neck and all that blood, and everyone's like, oh, it's the jugular vein, that's the carotid artery that's been injured. So the jugular vein is famous, but it's not really earned its place in our mythology. But I think it's mostly carotid injuries are the ones that are the life threatening, scary things as opposed to the jugular vein.
- [71:48]
Fidelity Representative
So we've been lied to. And in case if it ever comes up over dinner, maybe with extended family, someone mentions a stent, no one else knows what that is. You now are about to know that stents are these little mesh tubes that vascular surgeons might use to open up a blocked or collapsed vein. And they can be made out of metal or biodegradable materials. They can have medication embedded in them. Although the metal stents can become overgrown with scar tissue, which is why there are some newer options. So I hope that Answers some stent questions. Brooke Dombrowski, Amber McIntyre, and Mark Hewlett. Now, patron Rebecca Fitchett issued a command, a polite command. Please talk about aneurysms. And that was echoed by Kelly Shaver and Stephanie McKechnie. And the quick FYI. Is that an aneurysm? It means dilation in Greek. And it's when a blood vessel, like a vein or an artery, weakens or bulges outward like a little balloon. And that can cause symptoms, especially neurological ones, if it presses on structures in the brain and can even lead to strokes or insufficient blood supply to parts of the body. So managing high blood pressure can prevent aneurysms because then the pressure inside the veins is lower and it pushes outward less. And, Stephanie, I hope your dad's okay. And everyone else, I hope this helps you understand episodes of Grey's Anatomy. Now, most of my. My familiarity with the term aneurysm is from movies like in the 90s where someone has a house party and they're like, well, my mom sees this carpet, she's gonna have an aneurysm or something. And I thought, that's kind of insensitive. But it turns out that, yes, a sudden burst of anger or physical strain or untreated high blood pressure or just ongoing stress can cause an aneurysm or an existing one to rupture. So please chill for your own survival. And now other patrons. Jackie G. First timer Sean Kavanaugh, Haley Kirby, and EDM Asked about vascular surgery in general. Like what?

But we use microscopes, so we have loops to magnify what we're doing. But it does need to be a fine suture, which is why I was telling you about the delicacy of it, which is why I like it.

Go figure.
- [74:56]
ALIE Ward
Yeah, I guess CPR is next. We should both probably no cpr, but when tying a tourniquet, what's the protocol?
- [75:03]
Dr. Sheila Blumberg
So the tourniquets that are available now have their own. Each can be a little bit different. Right. But depending on where you're putting it, you want to go above the injury. Right. So if it's in the calf, you want to go in the thigh. If it's in the lower leg, then you want to go upper in the thigh. And when you place it, you have to try to turn the tourniquet so that it's tight enough that it's occlusive. And the point is, once you see that the bleeding has stopped. Right. That's the perfect point at which you can stop sort of turning the tourniquet because that's usually just a life saving measure. That should be, you know, limited time. Right. Because anytime the tourniquet's up, you have to start counting down the extremity that you're treating, whether it's the arm or the leg is not getting any blood flow. So once it's up, you start the clock on the tourniquet. I think that's the important part people forget because once you stop the bleeding, you've also stopped blood flow. And then depending on the situation, I don't want lay people getting too crazy about it, but you can also elevate the leg as you're putting the tourniquet on, just to decompress the venous system. And then put it on. Just put it on, turn it till the bleeding stops, and then someone's already calling for help. Please call an ambulance.
- [76:18]
ALIE Ward
Call an ambulance. Yeah, don't just rely on someone with a fanny pack tourniquet.

You'll figure, okay, onto some more chill stuff. Alex Vangelatos said, I've always wondered if there was a difference between what would be clinically considered varicose veins and just having very prominent veins, especially in lower legs. And feet and hands that really show off, AKA bulge and pulse after exercising, Alex says. And Alex, I found you. The article Lifting made my veins stick out, but here's why I Love them Anyway, in which a fellow vascular biologist and surgical angiologist, Dr. Jonathan Levison, explains that strength training causes the muscles to engorge and swell with plasma, which pushes the veins closer to the surface, making them be like, hey, especially if you happen to have thinner skin.

Yeah. Okay. Just be in a different position. Elevation. I tell a lot of patients who have vein problems, elevate the line legs as much as you can. The worst positions you can be in are sitting for too long and standing for too long. Moving, exercising is great. And then upside down, if you can, as much as you can. Or just elevate to whatever degree you know, if you're older and it's harder. I'm not saying to go a standing, you know, Inversion by acro.

The last two questions I always ask, what is the hardest part about surgery for you? What's the hardest part about your job? The most challenging part.
- [78:10]
Dr. Sheila Blumberg
Most challenging part is when I can potentially fix the acute problem, but I know that the patient's not going to make it. For example, this past week had a patient who clotted his leg. I can fix that, but if his heart is so damaged, me doing that is not going to change his ultimate outcome. And I think that for me is. Is still the most challenging part. Like, I can do the best thing that I can, but you're still not going to survive for whatever other reason. So that's still a challenge. And that will always be a challenge with this job.
- [78:43]
ALIE Ward
Well, you know, you mentioned that you sometimes see people when they're more advanced in a pathology. Any other advice that you want people to know to take care of that? Vascular health.
- [78:57]
Dr. Sheila Blumberg
Find a vascular specialist. There's not a lot of us, we're lucky in New York City. There's a lot of everybody. But just speaking around the country, there may not be a lot of people, especially if you're in rural areas, etc, who are specialists in this. And this is where telemedicine can be helpful because you can always connect with someone who's not necessarily regionally close, but can at least give you advice on how to get to the help that you need. A lot of patients don't have good access, so please find somebody who's a specialist in vascular care because it's a very sub specialized specialty and when done well, can be very helpful. So that, that's something I wish people knew more of. Yeah, we're kind of like an under dog specialty.

Dr. Sheila Blumberg
Depends on the case. But for the most part I don't have music anymore. I used to have music in the or, but then I found that my voice isn't loud enough for anybody to hear me when I need something. So I stopped with the music. And we only get music if I have everything that we need. And then we can have music because the team around me who's not focused, they like the music. And so I try to sort of meet them halfway because I want them to be happy so they can help me. And then depending if it's an emergency. No music. Yeah, yeah.

And this week it's that we have oak trees in the yard and I harvested a bunch of acorns a few weeks ago and I've had them in this cloudy jar in the fridge trying to cold bleach the bitter tannins out of them and then I got impatient so I tried to do one batch with boiling water and then drive them in the oven but they looked burnt to shit and my almost former spouse, your mother Jarrett, said that they were not palatable and this broke my heart. And I happened to meet up with my lovely friend and foraging ecology guest Everyone loves Alexis Nelson, AKA Black Forager on TikTok and Instagram and she was in town last week and she agreed to sample my acorns and I was nervous. Here's what happened I have one here.

Okay. Well, it hasn't hit me yet. Oh, no. Ally, you should try this. It's more nutty. Like the bitterness of the end is reminiscent of, like, a fragrance. Fresh walnut. This is edible. You could dry that and make a. And put it in a baked good.

Verdict? Edible. Jarrett then tried another. He said, oh, it was good, and that maybe he just got a weird one. So he remains my spouse. Now I'm gonna attempt to grind these into flour and make acorn cookies. And I'm gonna report back. But having a beloved and professional forager say, hey, you're not gonna die from ingesting the this and I found it pleasant is really enough of the goal for me. I'll let you know how it goes. All right, Be safe out there. Get those socks. Bye.
