A Case of Anterior Cerebral Artery Dissection presenting Subarachnoid Hemorrhage and Cerebral Infarction

Abstract

Recently the case of an intracranial arterial dissection has been reported in some papers. It is generally considered that the dissection of the internal carotid artery system was predominately performed in Europe and America, while in Japan on the other hand, most of the intracranial dissections were perforrmed in the posterior circulatory system. The arterial dissection of the anterior cerebral artery(ACA)was very rare and only 22 cases were reported previously. They were young adults, mean age 36 years(range 5-62), more often male(17 males, 6 females), and usually presented with ischemia due to occlusion distal to the dissection. In the past, only one case of subarachnoid hemorrhage and cerebral infarction simultaneously, occurring, had ever been reported. We describe a rare case of ACA dissection with a subarachnoid hemorrhage and cerebral infarction.
