The aorta is the main blood vessel that transports blood from the heart to the organs in the pelvis and to the legs. Sometimes the aorta narrows due to hardening of the arteries and this decreases the amount of blood that is delivered to the lower body including the legs. If this becomes severe, surgery is recommended. During this surgery, a bypass graft is placed between the aorta and the femoral arteries that branch off to the legs. Most patients must have an extensive preoperative work up including an arteriogram (similar to a heart catheterization). These patients can plan on a five to eight day hospital stay and a four to six week recovery period. After recovery, these patients may resume their normal activities.
