Peripheral Vascular Disease (PVD)
About Peripheral Vascular Disease (PVD)
Peripheral vascular disease (PVD) is a blood circulation disorder that causes the blood vessels outside of your heart and brain to narrow, block, or spasm. This can happen in your arteries or veins. PVD typically causes pain and fatigue, often in your legs, and especially during exercise. The pain usually improves with rest.
It can also affect the vessels that supply blood and oxygen to your arms, stomach, intestines and kidneys.
In PVD, blood vessels become narrowed and blood flow decreases. This can be due to arteriosclerosis, or “hardening of the arteries,” or it can be caused by blood vessel spasms. In arteriosclerosis, plaques build up in a vessel and limit the flow of blood and oxygen to your organs and limbs.
As plaque growth progresses, clots may develop and completely block the artery. This can lead to organ damage and loss of fingers, toes, or limbs, if left untreated.
