Peripheral Artery Disease
Peripheral Artery Disease (PAD) is a chronic condition in which partial or total arterial occlusion deprives the lower extremities of oxygen and nutrients. The narrowed arteries reduce blood flow to your limbs – usually legs – and your limbs do not receive enough blood flow to keep up with demand. This causes symptoms, most notably leg pain when walking.
Sources of blockage include:
- Atherosclerosis – 90%
- Atheromatous plaques
- Arterial Spasm

Signs and Symptoms
Poor wound healing
Coldness in legs or feet
Weak or absent pulses
Pale or bluish color to the skin
High blood pressure
60-90% are asymptomatic.
One in three people over the age of 50 with diabetes is likely to have PAD.
More than 160,000 amputations performed in the U.S. as a result of PAD a year.
More than 54% of patients who had amputations were not assessed to determine if blood flow could be restored.
67% of medicare patients who underwent a major amputation never had a revascularization procedure attempted to save the limb.
80% of medicare patients who undergo amputation never walk again.
30-50% two year mortality rate after amputation.
