Renovascular Disease

Renovascular disease is a progressive condition that causes narrowing or blockage of the arteries or veins that supply the kidneys. It's a general term used to describe three disorders: renal artery occlusion (blockage of the arteries supplying fresh blood), renal vein thrombosis (blockage of the veins carrying blood back to the heart), and renal atheroembolism (buildup of material blocking the smaller arteries within the kidneys). These conditions have no symptoms by themselves, but as kidney function begins to fail, patients may experience chest pain, nausea, fatigue, discoloration of the skin and puffiness of the hands and feet.
