title: [Two cases of acute aortic disease complicated by ischemic cerebrovascular disease].
abstract: Ischemic cerebrovascular diseases are commonly induced by atherosclerosis and cardiogenic embolization but rarely they occur in association with Takayasu's arteritis and aortic lesion such as aortic dissection and aneurysm. Here we experienced two cases of acute aortic disease complicated by ischemic cerebrovascular disease (CVD). Patient 1 was a 77-year-old male. He complained of dyspnea and left hemiparesis. He was brought to our hospital by ambulance. Left hemiparesis and dyspnea improved soon. The patient only complained of left lower extremity pain and physical examination revealed hypotension. Brain CT showed no abnormality but chest CT revealed aortic dissection. The resection of the intimal tear and replacement of ascending aorta and aortic arch with 28 mm Hemashield graft were performed under hypothermia and selective cerebral perfusion. The postoperative course was uneventful and he has been doing well. Patient 2 was a 67-year-old female. She was found lying unconscious and brought to our hospital by ambulance. Physical examination revealed right hemiparesis and hypotension. Brain CT demonstrated low density area in the left corona radiata and ruptured aortic aneurysm was seen in abdominal CT. Just after the examination, the patient suddenly complained of severe back pain and died despite cardiopulmonary resuscitation. Aortic lesions can manifest ischemic symptom involving multiple organs following their vascular disorder. Aortic dissection rarely occurs in association with ischemic CVD and in that case it is likely to be seen by neurologists. Aortic dissection and aneurysm deteriorate so suddenly that immediate diagnosis and proper treatment are needed.
