Aortobifemoral bypass surgery is used to bypass a blocked part of the large blood vessels in the abdomen and groin.

To bypass the blocked part of the blood vessel, blood is redirected through a graft. The graft is made of man-made material. This graft is sewn above and below the blocked vessel so that blood flows through the graft and around the blockage. The graft looks like an upside-down Y shape. The single end of the Y is sewn on the aorta. The two split ends of the Y are sewn below the blocked or narrowed areas of the femoral arteries.
