Aortofemoral Bypass Surgery
Aorto bifemoral bypass is a surgery used to create a new path for a clogged blood vessel in the abdomen or groin area. The surgery bypasses the circulation with a new artery around a blocked artery from abdominal aorta to common femoral artery in the groin to restore the circulation and relieve symptoms. The formation of blood clots and atheroma in the abdominal and pelvic aortas may block the blood supply to the legs which may cause severe mobility problems. The symptoms of blocked arteries will be pain the legs, calfs, thighs and buttocks known as intermittent claudication. If the symptoms were persisted they may cause severe pain during night time called critical limb ischemia. The other symptoms of critical limb ischemia are arterial ulcers and gangrene which may lead to leg amputation. Aortofemoral bypass surgery will be done to restore the blood supply to the legs which reduces the pain, heal the ulcers and to reduce the risk of leg amputation.
