Peripheral Artery Disease (PAD) | Diagnosis and Treatments

venous diseasePeripheral artery disease (PAD) is a common circulatory problem that affects 12 million people in the United States alone. It occurs when plaque builds up and clogs the arteries and prevents the extremities, primarily the legs but sometimes the arms, from receiving enough blood flow to keep up with demand. Studies show that PAD affects 5% of people between the ages of 60-69, and 15% of those 70 years of age or older. Peripheral artery disease is also likely to be a sign of a more widespread accumulation of fatty deposits in your arteries (atherosclerosis). The 5-year mortality rate for someone with PAD can be as high as 30%.


Risk Factors

The risk factors for developing carotid stenosis are similar to those for developing other forms of vascular disease and include:

  • Age
  • Smoking
  • High Blood Pressure
  • High Cholesterol
  • Diabetes
  • Obesity
  • Sedentary lifestyle
  • History of other cardiac or vascular disease

Symptoms

The most common symptom of peripheral artery disease is called "claudication," which is pain or cramping in the thighs or calves when walking, though some people may have no symptoms at all.

Other symptoms include:

  • Painful cramping in your hips, buttocks, thighs, or calves after activity, which is relieved with rest and reproducible when activity resumes ("claudication")
  • Leg fatigue or heaviness
  • Pain in your feet while at rest, usually on top of the foot
  • Numbness or tingling in your legs or feet
  • Loss of hair on lower legs or toes
  • Poor nail growth on toes
  • Coldness in lower legs or feet
  • Sores on your toes, feet, or legs that heal slowly or not at all
  • Change of the color of your legs or feet- pale or bluish
  • Weak pulse in your legs and feet

Diagnosis

Diagnosing peripheral artery disease is simple and painless since pulses in the legs and feet can be felt upon physical exam. However, the ankle-brachial index (ABI), which compares the blood pressure in the ankle with the blood pressure in the arm, serves as the most common diagnostic tool since it is more accurate than a standard pulse exam. This can also be combined with a non-invasive arterial duplex ultrasound, which allows us to look inside the arteries in an effort to track the flow of blood towards the feet, as well as identify any plaque buildup or blockages. For severe peripheral artery disease, an angiogram can allow a doctor to see the exact location of a blockage and if indicated, has the advantage of allowing treatment to be rendered at the same time.


Treatment

Many cases of peripheral artery disease can be treated with medications and risk factor modification. These include smoking cessation, supervised exercise programs and weight loss, antiplatelet medication (aspirin, Plavix), statins to lower cholesterol, blood pressure control, glucose control for diabetics, and optimization of any other cardiac or vascular conditions which might exist.

To alleviate symptoms, improve wound healing, or prevent the possibility of amputation, severe cases may require revascularization or restoration of blood flow to the legs and feet. This can be accomplished through either open surgical bypass or endovascular repair. A surgical bypass allows a blood vessel made of the patient’s own vein (or a synthetic fabric) to allow blood flow around the blocked or narrowed artery, while endovascular repair will require the arterial insertion of a mesh framework (angioplasty or stent) to keep the artery open.

In addition, there are several new advanced endovascular technologies such as an atherectomy, which can be used to remove the plaque from within the artery through a simple skin puncture that does not require an incision. Again, treatment should be individualized for each patient.

At Tenet Florida Cardiovascular Care, we prefer to utilize an “endovascular-first” approach for our patients and have had great success eliminating symptoms, healing wounds, and saving limbs and lives using our state-of-the-art endovascular tools and innovative techniques.

Dr. Joseph J Ricotta MD, MS, FACS Performs First VenaSeal Procedure in Southeast United States

Testimonials

"When I first saw Dr. Joseph Ricotta in his office, although he was very busy with patients, he took the time to speak with me, answering all my questions and reassuring me of our direction going forward. I have seen him a few times since and he still has the wonderful bedside manner he did the first time we met. He addresses all of my concerns, reassuring me that we would resolve any issues. I have seen many other doctors in the past for my complex vascular problems. Now, that I have found Dr. Ricotta, I finally felt hope that my issues would be properly diagnosed and resolved. I am so very glad to have found Dr. Ricotta. Other doctors could take a lesson from him on how to treat their patients."
