[Ruptured aortic arch aneurysm with hemorrhagic cardiac tamponade; report of a case]

We report a case of successful treatment of a ruptured distal aortic arch aneurysm with cardiac tamponade by using selective cerebral perfusion for protecting the brain. A 79-year-old man had sudden onset of severe chest and back pain. Chest computed tomography (CT) suggested an acute aortic dissection. He was immediately transferred to the emergency room of our hospital. Echocardiography performed on admission revealed intrapericardial fluid, and hemodynamic monitoring suggested cardiac tamponade. After pericardiocentesis and removal of 400 ml bloody fluid, his hemodynamic condition became stable. Enhanced chest CT showed ruptured distal aortic arch aneurysm with pericardial and pleural effusion. Emergency patch plasty of the aneurysm under extracorporeal circulation (ECC) was performed, assisted by selective cerebral perfusion and deep hypothermia. The patient's postoperative course was uneventful, except for minor transient respiratory troubles, and he was able return to his usual activity.
