Rupture of a dissecting thoracic aortic aneurysm into the pulmonary artery: successful surgical repair

Cardiovasc Surg. 1995 Dec;3(6):697-701. doi: 10.1016/0967-2109(96)82872-9.


A rare complication of dissecting thoracic aortic aneurysms is rupture into a cardiac chamber or great vessel with fistula formation. A case of congestive heart failure caused by a chronic DeBakey type I dissecting aortic aneurysm that ruptured into the pulmonary artery is reported. Surgical repair involved closure of the fistula followed by graft replacement of the ascending aorta and transverse aortic arch. A review of the literature revealed no previous reports describing successful repair of this lesion. A clinical picture consistent with concomitant aortic dissection and biventricular heart failure, especially when a continuous cardiac murmur is present, suggests the diagnosis of an aortopulmonary arterial fistula caused by a ruptured dissecting thoracic aortic aneurysm. Various imaging studies confirm the diagnosis.
