[Surgical management of acute type A aortic dissection with a complaint of disturbance of consciousness; report of a case].

A 50-year-old female was admitted to our hospital with a chief complaint of disturbance of consciousness (DOC). Left-sided hemiparalysis was noted on examination and cerebral infarction was diagnosed with total occlusion of the right common carotid artery revealed by cerebral angiography. Pharmacological thrombolysis (urokinase 720,000 U) was performed. Dissection of the right common carotid artery was noted after successful thrombolytic therapy. Enhanced chest computed tomography (CT) showed the acute type A aortic dissection involving the cerebral artery. Ascending aortic replacement was performed 4 days after the thrombolytic therapy to avoid brain edema and hemorrhagic infarction during cardiopulmonary bypass. The postoperative course was uneventful. In the case of acute type A aortic dissection with DOC, proper indication and optimal timing of the operation may help to improve patient survival.
