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
  • Thrombus
  • Emboli
  • Arterial Spasm

PAD Facts

  • 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.
