About Lower Extremity Arterial Disease
Lower Extremity Arterial Disease (LEAD) is the narrowing of arteries that supply blood to legs and feet. Just as coronary heart disease caused by atherosclerosis, LEAD is a result of reduced blood flow to the limbs due to the narrowing of artery caused by atheromatous plaque build up (formed by the deposition of cholesterol, fat or calcium) on the wall. Rupture of atheromatous plaque can lead to the formation of thrombus, which can further narrow the blood vessel or even lead to complete blockage.
