What is leg artery blockage?
Blockage in the leg arteries is predominantly caused by hardening of the arteries or atherosclerosis. Hardening of the arteries starts with fatty or cholesterol deposition in the wall of the artery. The cholesterol plaque builds up and worsens to the point of complete blockage depriving the leg of sufficient blood supply. Thirty million people in the United States have leg artery blockage.
