Peripheral Vascular Disease (Blocked Arteries)
Description
The buildup of plaque in the walls of arteries (atherosclerosis) is the usual cause of peripheral vascular disease. As the buildup continues, the artery becomes more and more narrow. During exercise these narrowed vessels are unable to provide adequate blood flow to the muscles causing pain and weakness. The symptoms are usually relieved by rest.
Symptoms
Pain in an extremity with exercise, cool extremities, weak pulse, numbness, skin discoloration.
Tests
A history and physical exam will be performed. CT angiogram or standard angiogram can identify the narrowing the artery.

Treatment
The treatment depends on the severity of disease and the location but may include: strict blood pressure control, diabetes control, smoking cessation, anticoagulants (warafrin/Coumadin), and anti-platelet medications (aspirin, clopidogrel/Plavix). Surgical procedures include intra-arterial stenting and bypass.
