[A case report of successful repair of an aortopulmonary fistula with partial dissection of the pulmonary artery].

We experienced a case of aortopulmonary fistula due to true thoracic aortic aneurysm. Surgical repair was electively performed when we found coexisting pulmonary arterial dissection. Under extracorporeal circulation, dissected flap was excised and the fistula was closed with his own pericardium, and his aortic arch and innominate artery were replaced with a piece of vascular prosthesis. His intra and post operative condition was stable, and postoperative course was uneventful. Prior to this case 13 surgically treated cases had been reported, and 5 had been successful. Among them, only 2 had been electively operated and both successful. Our case is the second case of aortopulmonary fistula associated with pulmonary arterial dissection.
