Peripheral arterial disease

PAD is a chronic disease in which blockage builds up in the arteries to the legs. This buildup typically occurs gradually. It is more common in older people. Smoking, high blood pressure, high cholesterol or triglyceride, diabetes, kidney failure and obesity increase your risk for PAD.


  • Fatigue or cramping of muscles while walking
  • Pain in toes or feet while resting
  • The wound on toes or feet


The causes of PAD include smoking, high cholesterol or high triglycerides, high blood pressure, diabetes, kidney failure, and obesity.


  • An initial diagnostic test for PAD is the ankle-brachial index (ABI) involves taking a blood pressure reading at the ankle and comparing it to that in the arm.
  • Additional supportive testing like TBI or oxygen readings around the wound may be done.
  • An Arterial Doppler study can show the presence of disease.
  • Typically an angiogram (CT / MRI or conventional) is done to determine where in the arteries plaque has built up to assess treatment options.


PAD is usually treated by aggressively managing the risk factors with lifestyle changes and medication. This includes quitting smoking, controlling blood pressure and cholesterol, controlling diabetes, and losing weight. In addition, an exercise program, if followed faithfully, can significantly improve the symptoms of PAD in many cases.

If PAD is causing serious symptoms, further treatments such as balloon angioplasty, stent placement, or surgical bypass can be very effective in improving the blood flow to the affected leg.
