A vascular bypass is a surgical procedure performed to redirect blood flow from one area to another by reconnecting blood vessels. Often, this is done to bypass around a diseased artery, from an area of normal blood flow to another relatively normal area. The other end is attached to an artery in your lower leg. The blood now flows through the graft, instead of through the section of the artery that was narrow or blocked. Improving the blood flow to your foot can relieve pain and help to heal any open areas (ulcers) on your foot. This surgery usually takes 3 to 4 hours.
