Peripheral vascular disease (PVD), also known as peripheral artery disease (PAD), occurs when blood vessels that supply blood to the limbs and organs are partially or completely blocked by the build-up of plaque (atherosclerosis). Plaque deposits gradually harden and narrow the vessels, which limits the supply of oxygen to the legs and other parts of the body. Screening for PVD can detect early signs of the disease so it can be treated to prevent further damage.
