Hello! I read in the newspapers that September is a Peripheral Vascular Disease Month, and that every September interventional radiologists participate in Legs For Life, a nationwide screening program. What I would like to know is what periphial vascular disease is. Thx!

Hello! Periphial vascular disease is a disease of blood vessels that are situated outside the heart and brain. It is usually narrowing of vessels that carry blood to the legs, arms, stomach or kidneys. There are two types of these circulation disorders: those that don't have an organic cause called Functional peripheral vascular diseases and those that have organic cause and are therefore called Organic peripheral vascular diseases. The first group doesn’t involve defects in blood vessels' structure. They're usually short-term effects related to "spasm" that may come and go. It can be triggered by cold temperatures, emotional stress, working with vibrating machinery or smoking. In the organic peripheral vascular diseases, there is a structural change in the blood vessels, such as inflammation and tissue damage. Peripheral artery disease is an example. It's caused by fatty buildups in arteries that block normal blood flow.
