PART 3: WHY DO MY TOES, ANKLES AND FEET HURT AT NIGHT? PERIPHERAL ARTERIAL DISEASE

Posted on by Michael Kokinos

In part one- and two of our four-part series on “Why do my feet hurt at night”, I discussed Venous disease and Raynaud’s Syndrome. In today’s discussion I want to focus on an even more common reason for why patients may suffer from leg pain at night: Peripheral arterial disease (otherwise known as PAD.)

As we’ve discussed in our earlier blogs, there are two kinds of blood vessels: Arteries and veins.

  • Arteries bring blood from the heart to the foot and toes under high pressure while
  • Veins bring the blood back from the foot to the heart under low pressure.

Over the course of anyone’s lifetime, blockages may build up in the arteries between the heart and the feet, especially in the pelvis and the legs.  Risk factors that increase the risk of formation of these blockages include:

  • Obesity
  • High blood pressure
  • High cholesterol
  • Diabetes
  • History of smoking tobacco.

As you may imagine, the tissue within the foot needs a certain amount of blood to supply the nutrients and oxygen necessary to keep the cells within the foot living.  Though a single, short segment blockage of the arteries in the leg may not result in any problems, multiple blockages from the pelvis to the foot may can make it difficult or even impossible for the cells within the foot to survive this lack of nutrients and oxygen.

What Does PAD Feel Like?

Typically, patients notice a gradual onset of pain in the forefoot and toes over the course of a few weeks to months.  As their blockages worsen, their pain becomes more severe.  Pain from PAD occurs in the forefoot and toes because those parts of the body are the furthest away from the heart and thus any blockage along the way from the heart to the toes can contribute to the lack of blood flow. One classic symptom of PAD pain is a burning, tingling, or numb sensation that can be partially relieved by hanging your foot off the bed or a chair.  In this position with the foot hanging down, gravity assists the flow of blood to the foot and toes and relieves the pain.  Typically, patients complain that when they lay flat at night, the pain in the forefoot and toes or just the foot in general will wake them up.  I always specifically ask patients if they are woken up at night by the pain.  If they are woken up by the pain, then I know the PAD must be very severe.

In some patients, the lack of blood flow is so diminished that there is also the development of ulcers, or defects in the skin with exposure of underlying fatty tissue, bone, and muscle or gangrene, the death of the tissue itself.

Even though PAD is a very severe and life limiting disease, specially trained vascular surgeons have many tools to combat it!  We can do a minimally invasive procedure called an angiogram that I described in an earlier blog post that you can access here!  Essentially, I access the diseased blood vessel with a needle and through that needle use contrast and x-ray to see where the blockages are.  Then, using balloons, stents, or self-expanding metal tubes, it is possible to re-open the blockages to re-establish blood flow to the impacted area.  For severe blockages, I also use a device called atherectomy that allows me to cut through and to remove the plaque responsible for blocking this vessel.  The procedure on average takes 1.5 to 2.5 hours and most patients can go home the same day.

PART 2: WHY DO MY TOES, ANKLES, AND FEET HURT AT NIGHT? RAYNAUD’S SYNDROME

Posted on by Michael Kokinos

Last week I wrote the first part of a four-part series about foot pain at night.  Specifically, I talked about venous disease as a cause of foot pain.

Today, I want to talk about another common cause of foot pain at night: Raynaud’s Syndrome. 

As a quick review, last week we talked about the two main types of blood vessels in our bodies: arteries and veins.  Arteries bring blood from the heart to the feet under high pressure.  Veins bring blood back from the foot to the heart under low pressure.

Raynaud’s Syndrome is a disease of the arteries, particularly the small arteries, in the feet.

(Though Raynaud’s can also affect the hands as well). 

Before we dive into Raynaud’s Syndrome though, I need to briefly review another anatomical system in our bodies that is involved in Raynaud’s Syndrome: The nervous system.

In general, we have two broad types of nerves.

  1. There are nerves that are responsible for sensation and for moving muscle and
  2. There are nerves that are responsible for regulation of bodily function.

Diving a little bit deeper into the kinds of nerves that regulate bodily function, there are the

  • Sympathetic nervous system: The sympathetic nervous system, amongst other things, is responsible for opening blood vessels in the legs and arms and increasing blood flow when exercise is necessary
  • Parasympathetic nervous system: The parasympathetic nervous system in similar fashion opens the blood vessels leading to the intestines to allow for the digestion of food.

In patients with Raynaud’s Syndrome, sometimes their sympathetic nervous system does not function properly resulting in the constriction of blood vessels that lead to the hands, fingers, feet, and toes.  When it happens, blood vessels in the fingers and toes typically first turn blue because of the lack of oxygen; then white because of the lack of blood flow; and finally red, once the constriction ends and the blood flow returns to the fingers and toes.  During this constriction of the blood vessels, patients can have significant pain, numbness, tingling, and, in very severe cases, ulcers (defects in the skin with exposure of underlying fat and muscle) and gangrene (black and dead tissue).

Interestingly, environmental and social triggers play a significant role in Raynaud’s Syndrome episodes of vessel constriction.  Factors including stress, caffeine, alcohol or other drugs, and cold temperature can all induce a painful episode with lack of blood flow to the hands and feet.

Not much is known about the cause of Raynaud’s Syndrome or specifically why it happens.  Sometimes, Raynaud’s Syndrome can occur on its own without any other related disease.  In other cases, the patient has another inflammatory disorder like lupus or Sjogren’s Syndrome that is known to be highly associated with Raynaud’s Syndrome.

Though we do not fully understand the causes of Raynaud’s Syndrome there are many treatment strategies that can help.  Starting with behavioral modifications and certain blood pressure medications that can reduce spasm to specific procedures aimed to reduce the spasm of the vessels induced by the sympathetic nervous system, there is so much that I as a vascular surgeon can do to help patients with Raynaud’s Syndrome.  If you think that you might suffer from Raynaud’s Syndrome, please do not hesitate to call our office on 408-376-3626 to schedule an appointment.

PART 1: WHY DO MY TOES, ANKLE, AND FEET HURT AT NIGHT? VENOUS DISEASE

Posted on by Michael Kokinos

One of the many questions I receive as a vascular surgeon is why do my feet hurt at night?  Though this question may seem simple, every person is different. Before I can provide you with “real” solutions to what’s causing this pain and what can be done to stop it, I need to evaluate multiple factors to understand “Why” this pain exists.  Over the next few weeks, I am going to explore the most common reasons for foot pain at night and why people can have pain in their feet at night caused by venous disease.

For the majority of patients Raynaud’s syndrome, Arterial disease, and Diabetic foot disease explain most of the reasons why people experience pain in their feet at night.  Though pain from problems with bones and muscle can play a role, pain due to these causes usually worsens during the day and with use, not when a patient is resting or lying flat.

In part one of this four-part series, I am going to discuss pain at night caused by VENOUS DISEASE.

Let’s start with a refresher on our bodies “plumbing” (Specifically, how does blood circulate around my body.)

  • Veins are blood vessels that bring blood BACK from the feet to the heart.
  • Arteries on the other hand are the blood vessels that bring blood FROM the heart to the feet.

Veins have specialized structures called one-way valves that allow blood to go up towards the heart but not back down towards the feet.  As we age, veins become dilated (start to leak) because the valves no longer seal properly. These leaky valves allow blood to fall back towards one’s feet which results in an increase in pressure within the veins at the ankle and just above the legs. Gravity tugs on the blood in our veins bringing it down to our feet which causes this increase in pressure

Interestingly, because of the curve that the veins take at the level of the ankle to enter the foot, the increase in pressure is not transmitted directly to the foot and toes.  The increase in venous pressure at the ankle typically results in

  • Varicose veins,
  • Swelling,
  • Dark skin discoloration from the leaking of red blood cells into the skin, and, in the worst cases
  • Ulceration.

Even without ulceration, however, the pain related to swelling and discoloration can be very severe.

People during their normal daily lives spend most of their days either standing or sitting.  Because of this, during the day gravity works in both positions to facilitate the pooling of blood around one’s ankles.  When patients come to me with pain in their feet, I always ask specifically if the pain is localized in the calves and ankles.  When pain is localized to the calves and ankles, I confirm a venous etiology by performing a physical exam and finding varicose veins, swelling, dark skin discoloration and/or ulcers between the ankle and the knee.

Pain that is reported in the foot and/or toes without the physical exam findings of varicose veins, swelling, dark skin discoloration, and/or ulcers between the ankle and the knee is NOT likely to be from a venous cause!  Though vein problems may sound or seem like a rare disease for those who have never had venous disease, patients with vein problems are one of the most common consults I see as a vascular surgeon.  Does foot pain wake you up at night? If you have any of the symptoms or appearance of the leg that I described above, please do not hesitate to call our office on 408-376-3626 to schedule an appointment.

One Final Note:

Though causes from the bones and muscles can play a role, foot pain that worsens at night is rarely due to these causes.  Often pain related to problems with bones and muscles worsen during the day and with use, not when any given patient is resting or lying flat.

Clues that can guide me as a vascular surgeon to the cause include throbbing and aching pain versus numbness and tingling associated with tenderness or pain located in the toes versus pain located in the ankle or just above the ankle in the leg.

FIXING BLOCKED ARTERIES

Posted on by Michael Kokinos

The most common disease that I treat as a vascular surgeon is a medical problem called peripheral vascular disease.  Specifically, peripheral refers to the legs, and vascular disease refers to blockages of the arteries.

Because peripheral vascular disease is the most common disease that I treat, I want to talk today about what I can do as a vascular surgeon to fix these kinds of blockages in the arteries!

First though, let me explain why blockages to the arteries of the legs are bad.  When not enough blood flow reaches the legs, patients can have pain in their calves or buttocks that limits their ability to walk longer than a city block.  When the blockages are very severe, they can also have pain in their feet and toes even when they are not moving or develop non-healing ulcers and gangrene.  When I open blockages in patients’ legs, I allow them to walk again, or I give them the ability to heal their ulcers and gangrene pain free.  The improvement in patient lives is the most exciting aspect of my job!

There are two main approaches to performing what we call revascularization. Revascularization refers to the opening of old passageways or creation of new passageways to bring blood directly from the heart to the foot without any obstruction.

  • Open Surgery: In the early decades of vascular surgery, namely the 1980s and 1990s the primary way to treat peripheral vascular disease was to perform an open surgical bypass.  If there was a blockage in the thigh, I would surgically expose above and below the blockage and take a synthetic tube or the patient’s own vein and then sew it above and below the blockage.  This would allow the flow of blood to bypass the blocked segment, hence, the reason we call this surgery a bypass!  Though this procedure does produce robust flow, it necessitates large surgical incisions that cause significant pain and are susceptible to poor wound healing and/or infection.

 

  • Endovascular Surgery: In the 2000s, an innovative approach called endovascular surgery started to become more widely used and is now actually standard of care today.  Indeed, I prefer to treat patients with peripheral vascular disease with endovascular surgery whenever possible.  We access the arterial system of the leg with a needle in the groin.  Through that needle we put in a strong wire and over that wire we can then advance several different instruments over catheters.  In general, there are three different techniques I can employ in my efforts to re-establish blood flow to an area that is no longer receiving blood due to some type of arterial blockage.
    • Balloons: The most basic instrument is a balloon that expands and breaks up the narrowing or blockage.
    • Stents: If the balloon does not work, we can use a self-expanding tube called a stent.
    • Atherectomy: If the stent does not work, we can use a special device called atherectomy.  Atherectomy involves the use of a device that can literally cut the plaque out of the artery and aspirate all the debris.

 

These three technologies allow the reopening of arteries from the toes to the pelvis and only necessitate a 2 mm puncture site in the skin of the groin to be used.  There is little to no risk of infection and the procedure can be performed several times over the course of the patient’s life.  On the other hand, surgical bypass can only be performed twice—three times—during the patient’s life due to the development of dense scar tissue after each operation.

 

If you have trouble walking because of pain in your buttocks or calves or have pain in your feet and toes or ulcers that will not heal, please do not hesitate to call my office today at 408-376-3626 to schedule an appointment.  The chances are that I will be able to help take your pain and ulcers away!

WHAT IS “ENDOVASCULAR” SURGERY?

Posted on by Michael Kokinos

As a vascular surgeon, I perform two very different types of surgery: Open Surgery and Endovascular Surgery.

  • Open surgery is just as you might think!  It involves making an incision with a scalpel and using various tools like forceps, scissors, electrocautery, and needle drivers to expose and then repair specific structures.  Since the beginning of surgery itself, all surgeons, not just vascular surgeons, have been practicing open surgery.
  • Endovascular surgery is a recent development that only began in the 1990s.  Motivated by the desire to perform minimally invasive and less harmful interventions on the most sick and highest risk patients, pioneers in vascular surgery developed endovascular techniques.

Though the concept is simple, endovascular surgery now allows vascular surgeons to solve a multitude of problems with blood vessels very differently than they have in the past. Using advanced minimally invasive surgical techniques, vascular surgeons can treat many forms of vascular disease without the need to “cut-open” their patients to treat extraordinarily complex and in some cases life threatening diseases.

Endovascular surgical techniques utilize ultrasound (sound waves) to place the tip of a hollow needle into a blood vessel.  Once these hollow needles have been placed through the needle, we place a very stiff wire that allows us to advance large tubes called catheters into the vessel.  Catheters have many different functions depending on the situation and are used to re-establish blood flow in vessels that are diseased and or blocked.

For peripheral vascular disease, there are blockages in the legs of a patient that prevent blood flow from reaching the foot.  For peripheral vascular disease we can use balloons on the end of the catheter that are inflated to open a blockage.  If balloons do not work, then we can put a self-expanding metal mesh tube on the end of a catheter and then deploy it inside the blockage, thereby keeping it open.  There is also a technology called atherectomy which literally means cutting out plaque.  The atherectomy device has a cutting edge that sands down the plaque and then a suction function that removes all the debris.

For aneurysms, which are dilations of a blood vessel that can rupture, we use stent grafts, which are self-expanding metal mesh tubes that are lined with an impermeable fabric.  We place the stent graft above and below the aneurysm, thereby sealing it from the pressure created by the heart and preventing rupture.

At the end of these endovascular cases, the patient only has one or two 1 mm in size punctures over the arteries that were accessed.  Contrast this to the classic open surgeries where patients could have incisions up to 10 to 20 cm!  As a contemporary vascular surgeon, I take pride and joy in being able to offer both types of surgical interventions to my patients.  If you or your loved one may be suffering from vascular disease, please do not hesitate to call our office at 408-376-3626 to schedule an appointment today!

WHY DIABETES IS BAD FOR YOUR FEET

Posted on by Michael Kokinos

Everyone knows that diabetes, otherwise known as high blood sugar, is bad for you.  What most people don’t realize, however, is just how many people in the US have diabetes and the impact diabetes has on their feet. In 2021 the CDC released the following info graphic:

 

As a vascular surgeon the primary issue I see in patients with diabetes is foot infection.  But how does diabetes specifically make it more likely for patients to develop foot infections?  My hope in writing this blog today is to give patients a complete understanding of what happens to the feet of people with diabetes.

High concentrations of sugar in the blood lead to what physicians call an inflammatory state in the arteries, or blood vessels that take blood from the heart to the rest of the body.  The inflammatory state results in scarring and narrowing in the arteries.  However, only smaller blood vessels such as the ones in the eyes, toes/feet, and kidneys are affected significantly.  In the feet, the scarring affects both arteries that supply the feet and toes themselves as well as the arteries that supply the nerves.

With a lack of blood flow to the nerves of the feet, patients lose sensation in their toes and feet.  Thus, when a patient has an accidental injury like a scratch or a bruise, no pain is registered, and the area continues to be traumatized and unable to heal.  In addition, the muscles of the foot lose their ability to contract, and they then relax into positions that create bony prominences that erode through the skin and cause ulcers.  Finally, the nerve damage also results in the loss of natural oils in the skin that then makes the skin dry and prone to cracking.  This cracking then increases the chance of ulceration and foot infection.

As you can see, diabetes is very bad for the foot!  If you are diabetic and see an ulcer on your foot or have either pain or numbness, do not hesitate to call our office at 408 376-3626 to schedule an appointment today! Visit our website at www.southbayvascular.com to learn more. We Can Help!

YOU HAVE A BLOOD CLOT. NOW WHAT?

Posted on by Michael Kokinos

One of the most common consultations that we as vascular surgeons receive is for deep vein thrombosis, otherwise known as blood clots.  Deep veins refer to the location of the vein that has the problem.  In the legs we have two main sets of veins: Deep and superficial.  Deep veins are within the muscle and close to the bones whereas superficial veins are close to the skin; hence their names!

Thrombosis refers to the process of the blood turning from a liquid into a solid form.  Normally, thrombosis occurs in response to an injury to stop bleeding from a wound.  However, when thrombosis occurs in the deep veins, it stops blood from being transported from the foot back to the heart.  The obstruction of flow results in swelling and pain below where the thrombus, or clot, has formed.

There are many causes of blood clots, but the most common causes include:

  • Traveling for extended periods of time in a sitting or resting position.
  • Trauma, including accidents which cause broken bones or bruises.
  • Narrowing of the veins of the pelvis, and
  • Specific genetic mutations that increase the likelihood of the blood forming clots. 
  • In older patients, another potential cause of blood clots without any other cause is cancer.  Cancer, unfortunately, can result in the release of chemicals and hormones within the body that make clotting more likely.

For patients who develop a blood clot in the context of traveling, narrowed pelvic veins, or having a traumatic injury to the affected leg, treatment involves a 3-month course of blood thinning medication followed by ultrasound tests to determine the stability of the clot.  If the symptoms improve and the clot remains stable, then the medication to thin the blood can be stopped at 3 months.

For travelers who are forced to sit for extended periods without being able to move, making an effort to walk around intermittently throughout the traveling can be helpful.  For example, on the plane, every 30 minutes stand up and walk up and down the aisle 3-4 times.  For patients who have a traumatic injury to their leg, the best choice would be to avoid, if possible, situations that led to the particular accident.  Finally, in patients with narrowed pelvic veins, I as a vascular surgeon can help relieve the narrowing with a special minimally invasive procedure called a venogram.  In the procedure, I place a self-expanding tube called a stent into the compressed vein via a small 2 mm puncture site in the groin to make sure the compressed vein remains open.

For those patients who did not have a traumatic accident, narrowed pelvic veins, recent travel, or a high suspicion of cancer, referral to a hematologist, or a doctor who specializes in disorders of the blood, can be helpful.  The hematologist can help order special genetic tests to determine if there is a genetic predisposition to forming clots.  In patients who do end up having genetic mutations, long-term placement on blood thinning medications can help prevent further events.

If you are anyone that you know is suffering from a blood clot, please do not hesitate to call our office on 408-376-3626 to schedule an appointment!  The expertise that vascular surgeons have in this area of medicine is critical to ensure a good outcome!

TRANSCAROTID ARTERY REVASCULARIZATION: THE FUTURE OF CAROTID SURGERY

Posted on by Michael Kokinos

One of the most gratifying problems we help treat for patients is carotid artery disease.  The carotid arteries supply the brain with blood.  In patients with high blood pressure, high cholesterol, diabetes, and a history of smoking, the carotid arteries can become narrowed and form blood clots that then go into the brain and cause strokes.  Traditionally, vascular surgeons have fixed this carotid artery narrowing’s with a surgery called a carotid endarterectomy.  The carotid artery is dissected out and cut open.  The plaque is then removed, and the carotid artery is sewn back together.

Over the past five years, however, I have had the opportunity to perform a new technique involving carotid stenting called trans carotid artery revascularization or TCAR.  Stents are self-expanding metal tubes that we can use in the carotid artery to stop clots from forming in narrowed areas.  TCAR uses a suction machine to reverse flow in the carotid artery during the placement of a stent to minimize the risk of inadvertent stroke during the procedure itself.  After having performed over 20 of these procedures in the past two years, I can say with confidence that the flow reversal and stenting that TCAR provides is a highly safe and successful way to treat carotid artery disease.  Furthermore, the length of the incision, postoperative pain, and risk of nerve damage and bleeding are all much less with TCAR than with CEA.

I am so happy to be able to offer this revolutionary, safe, and effective therapy to all my patients at South Bay Vascular Center.  Should you or anyone you know have any problems with your carotid arteries or a stroke, please do not hesitate to call us today at 408-376-3626 to schedule a consultation.

WHY DON’T THE WOUNDS ON MY LEGS AND FEET HEAL ANYMORE?

Posted on by Michael Kokinos

Hi! Dr. Lau here again with South Bay Vascular. Today, I wanted to shed some light on one of the most common issues that we see in vascular surgery, non-healing wounds of the feet and toes. My hope is that after reading this blog you will have a better understanding of what causes leg wounds and ulcers; why sometimes they won’t heal on their own, and what we in vascular surgery can do to help them heal.

Ulcers, generally speaking, develop because of TWO main causes: nerve damage induced by diabetes and lack of blood flow. When patients have elevated levels of sugar in their blood with diabetes, the sugar forms toxic compounds that damage nerves in the foot. Consequently, the patient cannot feel injuries that would otherwise cause a normal patient to adjust position to stop the injury. With this loss of sensation ulcers form at the point of repeated injury that the patient cannot feel.

The second cause, a lack of blood flow, develops over decades in patients who smoke and who have high blood pressure and high cholesterol. These medical problems cause hardening and narrowing of the blood vessels, otherwise known as atherosclerosis.

In patients with diabetes, I coordinate carefully with my podiatrist colleagues who are experts in specialized footwear and surgical interventions that alleviate common areas of trauma. In patients with poor blood flow, I, as a vascular surgeon, can perform minimally invasive surgery to restore blood flow to the affected area. We use wires and specialized tubes to gain access to the blood vessels and then use balloons to break open the narrowing’s and self-expanding tubes called stents to keep the vessels open. Afterwards, we use a specialized x-ray machine called fluoroscopy to see that the narrowing’s have opened again to allow blood to flow back to the area. Patients usually leave to go home the same day with only a 2-millimeter puncture in their groin and are back to normal activity the day after surgery!

If you or anyone you know has a wound on their leg, foot or toe that hasn’t healed in more than two weeks, please call our office at 408 376 3626 to schedule an appointment.

FOOT PAIN AT NIGHT: IT MIGHT BE MORE SERIOUS THAN YOU THINK

Posted on by Michael Kokinos

Many patients over the age of 65 who have a history of smoking, diabetes, high blood pressure, and/or high cholesterol wake up at night with pain in their foot or toes. Some believe this is arthritis or gout; others think it is the result of just spending too much time on their feet during the day.  Patients often self-adapt to this problem, as it usually develops slowly over time, but when questioned about their sleep habits, they will sometimes tell you that they sleep in a recliner or they sleep with their leg hanging over the side of the bed to make their pain go away.

It is very common for elderly patients to get up at night to go to the bathroom. Sometimes, however, it’s actually foot pain that wakes them up.  Once up, they get out of bed because that makes their feet feel better (again due to gravity) and after walking to the bathroom they can go back to sleep, pain -free for a couple of hours.  Even that small amount of walking helps to get their blood flowing again and makes it easier for them to go back to sleep.

Sometimes, foot pain at night is the sign of a more serious condition.

  • Foot pain at night may be related to having poor circulation in the foot. The name for this in medical terms is “rest pain”. This is not “pain at rest” but rather pain that happens because the circulation cannot support the tissues even when they are at rest.

Foot pain at night may be an early warning sign of critical limb ischemia.

  • Chronic Limb Ischemia is another term for lack of blood flow;  if you experience this rest pain at night and it goes away after hanging your foot over the side of the bed or chair you are sleeping in, immediately call and speak with your doctor to set up an appointment for them to evaluate your symptoms. Although it may come on slowly, the arteries in your feet may be so blocked that they cannot even deliver the minimal amount of oxygen the tissues in the foot and toes need to keep them nourished. Left untreated, this blockage can lead to a more serious problem, amputation or even death.

What’s important for the patient to realize is that chronic limb ischemia causes the foot and leg to get swollen, so the patient is often MIS-DIAGNOSED with a vein problem, not an arterial problem

If this sounds like something you or someone you love is experiencing, it is important to tell your primary care doctor OR schedule an appointment DIRECTLY with a vascular surgeon. These symptoms are a sign that your body is giving you that you may need immediate help. This truly is a sign that your foot is starving for oxygen and blood and that if left untreated, might lead to an unnecessary amputation. Help is possible, however and if treated early enough, those suffering from these symptoms can be helped significantly.
