The Top Doctors Specializing in PERIPHERAL VASCULAR DISEASE in AZ

Peripheral arterial disease (PAD), also known as peripheral vascular disease or peripheral artery disease, is plaque buildup in your leg arteries that carry oxygen and nutrient-rich blood from your heart to your arms and legs. Shaped like hollow tubes, arteries have a smooth lining that prevents blood from clotting and promotes steady blood flow. When you have peripheral artery disease, plaque (made of fat, cholesterol and other substances) that forms gradually inside your artery walls slowly narrows your arteries. This plaque is also known as atherosclerosis. Many plaque deposits are hard on the outside and soft on the inside. The hard surface can crack or tear, allowing platelets (disc-shaped particles in your blood that help it clot) to come to the area. Blood clots can form around the plaque, making your artery even narrower. If your arteries become narrowed or blocked with plaque or a blood clot, blood can’t get through to nourish organs and other tissues. This causes damage ― and eventually death (gangrene) ― to the tissues below the blockage. This most often occurs in your toes and feet. The rate at which PAD progresses varies with each person and depends on many factors, including where in your body the plaque forms and your overall health.
