What is Peripheral Vascular Disease? Peripheral vascular diseases (PVDs) are circulation disorders that affect blood vessels outside of the heart and brain. PVD typically strikes the veins and arteries that supply the arms, legs, and organs located below your stomach. These are the blood vessels that are distant from the heart. They are known as peripheral vessels. In PVD, blood vessels are narrowed. Narrowing is usually caused by arteriosclerosis.
