Aortic bifemoral (aortobifemoral) bypass is a surgical procedure performed in patients with atherosclerotic disease of the infrarenal aorta and iliac vessels. Most patients who undergo this procedure have symptoms of claudication, impotence, and poorly healing ulcers. Examination usually reveals absent or very weak femoral pulses.
Indications for aortic bifemoral bypass include the following:
- Atherosclerosis if the abdominal aorta or iliac arteries
- Presence of severe claudication symptoms
- Nonhealing ulcers in the extremities
- Aortic aneurysms
- Acute abdominal aortic occlusion
- Critical limb ischemia
The procedure can be combined with renal artery or superior mesenteric artery revascularization if symptomatic stenoses are present in these visceral vessels.
