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

The ruptured aortic arch aneurysm with cardiac tamponade is rare and has severely high mortality. We report a case of ruptured aortic arch aneurysm with cardiac tamponade. A 66-year-old man who had syncope attack was transferred to city hospital. Brain computed tomography (CT) showed no significant lesion and he admitted to our hospital for suspecting of aortic dissection. Chest CT showed ruptured aortic arch aneurysm and pericardial effusion. Emergent operation was done on the same day. It was found that the hematoma beneath the tunica adventitia existed at the distal arch and extended to the ascending aorta. Cardiac tamponade was caused by rupture of subadventitial hematoma in pericardial space. Aortic arch replacement was performed using selective cerebral perfusion under deep hypothermia. Postoperatively, he had no cerebral complication and was discharged uneventfully.
