Peripheral Artery Disease

What is Peripheral Artery Disease?

Peripheral arterial disease (PAD) is caused by plaque buildup inside the blood vessels carrying blood to your legs.

An estimated 8.5 million Americans and more than 200 million people worldwide have PAD. If you have PAD, you are at increased risk of heart attack and stroke. The 5-year death rate among patients diagnosed with PAD may be as high as 33 percent, with most deaths due to heart attack and stroke.

Risk Factors

  • Smoking
  • High Cholesterol
  • High Blood Pressure
  • Diabetes
  • Renal Failure
  • Obesity

Who is at risk for PAD?

  • Patients under 50 years of age with diabetes mellitus and one or more additional risk factors for atherosclerosis/plaque buildup
  • Patients 50 to 64 years of age with one of the risk factors above or family history of PAD
  • Patients 65 years of age or older
  • Patients with known atherosclerotic disease/plaque buildup in another part of the body including the heart, neck (carotid artery), arms (subclavian artery), abdomen (abdominal aortic aneurysm, renal artery narrowing, or narrowing in arteries of the bowel).

Signs/Symptoms

The most common symptom of PAD is called claudication, which is leg pain that occurs when walking or exercising and disappears at rest.

Other symptoms of PAD include discoloration, numbness, and tingling in the lower legs and feet, coldness in the lower legs and feet, and ulcers or sores on the legs or feet that don't heal.

How is PAD Diagnosed?


  • Your doctor will perform a complete history and physical exam and possibly order blood tests.
  • Ankle-brachial index or ABI is calculated using blood pressures from the arms and feet at rest. An ABI that is less than 0.90 confirms the diagnosis of peripheral arterial disease.
  • Other tests may include a combination of Duplex Ultrasound of the leg arteries, blood pressure measurements of the blood flow in the legs (PVR, Segmental Pressures).
  • TcPO2/TCOM test which measures the oxygen level of the tissues below the skin using sensors on the foot is helpful in patients with ulcers/sores/wounds.
  • CT Angiogram or MR Angiogram of the legs which are CT or MRI scans of the arteries in the legs using contrast injected into an arm vein.

How is PAD Treated?


Depending on the location and severity of your PAD and your risk factors, your doctor may prescribe an exercise program, medications, help you stop smoking, or recommend treatment. Treatment can include outpatient procedures such as angioplasty or stent placement.

Vascular Interventional Radiologists pioneered angioplasty and stenting, which was first performed to treat peripheral arterial disease. Using various cameras to see inside the body without surgery, a vascular interventional radiologist guides a small catheter which looks like IV tubing through the femoral artery in the groin to the blocked artery in the legs.

Then, he or she inflates a balloon to open the blood vessel where it is narrowed or blocked (angioplasty). In some cases, the blocked artery may not stay open with angioplasty alone, and a scaffold is needed. These treatments are outpatient, minimally invasive, performed with local anesthesia and light sedation medications, using a tiny nick in the skin the size of a pencil tip. Recovery is usually a few hours or possible one-night hospital stay. Most patients have an immediate improvement in their symptoms.

We will schedule follow-up appointments every few months to make sure your symptoms are not returning.
