Aorto-bifemoral bypass is a procedure used to treat severe peripheral artery disease (PAD) by bypassing blockages in the aorta and iliac arteries, which supply blood to the lower extremities. During the surgery, a graft is used to reroute blood flow around the blocked arteries, restoring circulation to the legs and alleviating symptoms such as pain, cramping, or non-healing wounds.

Aorto-bifemoral bypass is often recommended for patients with advanced PAD or critical limb ischemia, helping to prevent complications such as gangrene or amputation.
