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!

PERIPHERAL ARTERIAL DISEASE (PAD); EARLY RECOGNITION AND REFERRAL TO A VASCULAR SURGEON

Posted on by Angelica Rodezno

According to the U.S. Centers for Disease Control and Prevention (CDC), approximately 18 million people in the United States suffer from Peripheral Artery Disease (PAD), a common circulatory problem in which narrowed arteries reduce blood flow to the limbs. Estimates suggest that anywhere from 12 to 20 percent of individuals over the age of 60 are living with PAD. Approximately 160,000 to 180,000 of the estimated 18 million Americans with PAD will undergo a limb amputation as result of PAD-related condition this year, resulting in lower quality of life, high medical costs, and shorter life expectancy.

But even with these alarming numbers, APPROXIMATELY 3 OUT OF 4 AMERICANS are unaware of PAD Symptoms.

Severe PAD symptoms include:

  • Leg pain,
  • Wounds on the toes or feet,
  • Gangrene and
  • A loss of leg mass compared to the rest of the body.
  • Individuals are at greatest risk for PAD if you have high cholesterol, high blood pressure, or diabetes.

Dr. Polly G Kokinos, a board certified Vascular and General Surgeon in Campbell, CA. is recognized as one of the regions foremost authorities in the diagnosis and treatment of PAD. With offices in both Campbell and Gilroy, CA. Dr Kokinos has dedicated her entire career to serving the South County community as an independent physician and as a pioneer in the evaluation and treatment of patients suffering from Peripheral Arterial Disease.

Unburdened by the productivity metrics, financial benchmarks and administrative red tape commonly found in Big Box Medical Systems, Dr. Kokinos has focused her entire career on providing exceptional vascular care building her practice one patient at a time. Her Campbell Surgery center, a nationally accredited Vascular Surgery Center of Excellence, is entirely dedicated to treating patients suffering from complex vascular surgical disorders. Unlike a traditional hospital or university operating room, Dr. Kokinos’ surgery center is entirely dedicated to addressing vascular issues ensuring that she has the most advanced imaging and device technology available anywhere in the world.

Unfortunately, even with all of her skill experience and technology, many patients don’t find Dr. Kokinos until its too late. Many patients go under diagnosed or undiagnosed until it is too late and their medical condition has declined to the point where no one can help. In this circumstance patients lose limbs, suffer unnecessarily and become an incredible burden on their family and loved ones. In the worst cases, patients can die if their leg wounds are left untreated.

In an effort to help front line medical doctors better evaluate and diagnose peripheral arterial disease Dr. Kokinos has spoken extensively to the Primary Community Care Team (Internists, Podiatrists, Orthopaedic Surgeons) in the management of lower extremity arterial and venous disease. As is the case in most instances, early detection of peripheral arterial disease has a dramatic impact on the success of any future treatments.

Bridging this educational gap was the topic of a recent talk Dr. Kokinos was honored to give in March of 2020 to a group of Northern California primary care physicians. The focus of this talk was to help primary care and referring physicians better understand the etiology (the cause of a disease or condition) its diagnosis, management, and referral strategies for peripheral arterial and venous disease.

The key takeaways from her talk are outlined below:

  • Prevalence of PAD and Venous Disease have reached epidemic proportions.
  • Peripheral Arterial and Venous Disease are both associated with high rates of disability and death.
  • Identifying arterial disease early may improve a patients quality of life and allow early medical and surgical interventions to lower the risk of critical limb ischemia and amputation.
  • Identifying venous disease can greatly improve a patients quality of live and lower their risk of dying from this disease.
  • Despite greater awareness, PAD and Venous disease are still under-recognized and under treated.
  • Due to the complex nature of vascular disease, an evidence-based multidisciplinary approach is essential to early assessment, proper diagnosis and optimal treatment
  • Minimally invasive endovascular techniques now enable vascular surgeons to treat significantly higher numbers of patients with a lower complication and death rate
  • Appropriate referrals to specialists must be emphasized if physicians are to continue to improve the lives of patients with PAD

Her underlying message to the audience was that primary care physicians are a patients first line of defense. Helping patients achieve better outcomes requires early recognition and management on the part of the primary care physician and that early referral to a vascular surgeon is essential to the successful outcome of advanced treatments.

If you or anyone you love suffers from any of the symptoms outlined in this blog, we would be honored to speak with them to discuss their symptoms. Call Dr. Kokinos’ office at South Bay Vascular Center to schedule an appointment at 408-376-3626.
