Artery bypass surgery, coloured angiogram. Back view of the legs of a 67 year old patient who has had two bypass operations (thick white lines, top and right) to treat arteritis. Arteritis is a disease where the walls of arteries become inflamed, usually as a result of infection or auto-immune response. Severe stenoses (restrictions) in the arteries means there is limited blood flow in the leg, and this can result in necrosis (tissue death) or gangrene. Bypass operations allow blow flow to return to the lower limbs. An angiogram is an X-ray technique that uses a contrast dye to highlight blood vessels.
