Peripheral Arterial Disease Q & A

What is peripheral arterial disease?

Peripheral arterial disease (PAD) is a disease caused by plaque buildup inside major arteries in the body, most often the legs. This accumulation causes your arteries to narrow, leading to symptoms like:

  • Poor circulation and cold limbs
  • Leg pain or cramps, especially during activity
  • Tired, weak legs
  • Skin color changes
  • Sores or ulcers that don’t heal

The risk factors for PAD include smoking, diabetes, high cholesterol, high blood pressure, and a sedentary lifestyle. Fatty deposits accumulate and cause your arteries to narrow and harden. The narrowing arteries block blood flow and deprive your extremities of oxygen.

How is peripheral artery disease diagnosed?

After giving you a physical exam and learning your personal health history, Dr. Kasthuri may perform an ankle-brachial index test and an angiogram to assess blood flow to your legs.

The ankle-brachial index is a comparison of the blood pressure reading in your ankle and your arm. If the blood pressure in your leg is lower than the blood pressure in your arm, you likely have PAD.

An angiogram involves injecting dye into the veins and assessing blood flow with an X-ray camera called a fluoroscope.

When is surgery required for peripheral arterial disease?

Surgery is advisable if you have a severe case of PAD because artery blockages can be life-threatening. If a clogged artery blocks oxygen to your legs, the tissues may start to die, leading to gangrene. Once gangrene sets in, you may risk amputation.

PAD also increases your risk of vascular inflammation and blood clots. It’s often a sign that other arteries are clogged too, leading to coronary artery disease, heart attack, and stroke.

What does surgery for peripheral arterial disease involve?

Dr. Kasthuri performs angioplasty for PAD, which involves placing a stent, or balloon, in the narrowed artery. First, he passes a catheter through the artery and injects contrast liquid to locate the narrowing.

Next, Dr. Kasthuri inserts a stent to expand the artery and hold it open. Angioplasty reopens the blood vessel and restores proper blood flow.
