Twisting of an aorta-coronary bypass conduit: a complication of coronary surgery.
Twisting of an aorta-coronary bypass conduit was observed at necropsy in each of three patients. Three twists (540 degrees) just distal to the aortic anastomosis caused total obstruction of the bypass conduit to the left anterior descending coronary artery in one patient. A single twist (180 degrees) occurred in a bypass conduit in each of the othe two patients. Obviously, prevention of graft twisting is essential for successful bypass grafting.
