Arterial grafts. Computer artwork of a human body, showing a bifurcating (branching) graft of the aortic artery (lower centre). The abdominal aorta is the major artery supplying blood to the lower body, and is often the site of arterial disease where it forks and branches into the two common iliac arteries. At this fork, aneurysm (ballooning) or atherosclerosis (narrowing caused by fatty deposits) of the aorta may occur. Damaged iliac arteries can be corrected with grafts, which normalize blood flow into the legs.
