Definition

Peripheral artery disease (PAD) is disease of any blood vessel that is not part of the heart or brain. PAD is caused by deposits of fatty material in arteries of the legs. Since arteries carry oxygen-rich blood to the cells of the body, a reduction in blood flow can cause organ failure.

Causes

PAD is usually caused by a gradual buildup of plaque called atherosclerosis that happens within the arteries. Other causes include blood clots or embolisms, congenital heart disease, and inflammation of the blood vessels called vasculitis.
