Abstract
An 81-year-old man was scheduled to undergo surgery for an aortic arch aneurysm. The patient was admitted to a local hospital because of congestive heart failure. Computed tomography showed an aortopulmonary fistula due to an aortic arch aneurysm. The patient was therefore transferred to our hospital for undergoing total arch replacement with closure of the fistula and coronary artery bypass grafting (AO-SVG-#4PD). It was difficult to maintain circulation during the cardiopulmonary bypass because of an aortopulmonary shunt. The patient required percutaneous cardiopulmonary support for 2 days and was discharged 49 days after the operation. Aortopulmonary fistula is a rare, potentially fatal condition that can lead to death because of right heart failure.
