[Surgical Management of a Severely Calcified Ascending Aorta Using Intra-Aortic Balloon Occlusion].

A severely calcified ascending aorta increases the risk of perioperative cerebral damage in cardiac surgery. Conventional aortic valve replacement using an external aortic cross clamp may be dangerous in patients with this morbidity. We used an intra-aortic balloon occlusion catheter(IABOC)to minimize risks of aortic valve replacement(AVR) in an 81-year-old man with severe aortic stenosis combined with a severely calcified aorta. IABOC was introduced to the ascending aorta via the right femoral artery by esophageal echocardiography. The precise site of the inflated balloon was confirmed by the pressure of the right radial artery and was secured by 2 tourniquets around the ascending aorta. The postoperative course was uneventful. Our technique can contribute to prevention of embolic complications in some patients with a severely calcified ascending aorta.
