Peripheral Vascular Disease (PVD)
Peripheral vascular disease (PAD) is a disease of the blood vessels outside of the heart and brain. The vessels that carry blood to the legs, arms, stomach or kidneys are often narrow, causing two types of circulation disorders: functional and organic peripheral vascular diseases.
Functional peripheral vascular diseases do not have an organic cause and do not involve defects in blood vessels' structure. This disorder usually comes and goes with short-term effects and may be triggered, for example, by cold temperatures, emotional stress or smoking. Structural changes in the blood vessels such as inflammation and tissue damage result in organic peripheral vascular diseases.
There are certain signs and symptoms to look for when diagnosing peripheral vascular disease (PVD) and other vascular diseases.
