What is arteriosclerosis obliterans?

Arteriosclerosis obliterans, or peripheral artery disease, occurs when arterial plaque and fat deposits build up in the arteries that feed the limbs. This makes the arteries too narrow to allow a sufficient blood flow to the extremities, especially the legs. Healthy arteries dilate to allow for heavier blood flow when it is needed, for instance, when you are exercising. If you suffer from arteriosclerosis obliterans, the walls of your arteries could stiffen and lose their ability to dilate when necessary. Eventually, your arteries could become so narrow that blood flow is always insufficient, even when you are at rest.
