Abstract
The authors have successfully treated a case of dissecting aneurysm of the anterior cerebral artery, which presented with cerebra] infarction followed by subarachnoid hemorrhage. A 48-year-old female patient experienced severe headache and right hemiparesis. CT scan revealed cerebral infarction at the territory of the left anterior cerebral artery. One month later after conservative treatment, the patient experienced repeated bouts of severe headaches and eventually lost consciousness. CT scan revealed subarachnoid hemorrhage. An angiogram performed on the left carotid manifested segmental narrowing and dilatation at the left A1 and A'2 portion of the anterior cerebral artery. These findings suggest a dissecting aneurysm. The authors utilized the pterional approach in performing the operation. The left Al and A2 portion of the anterior cerebral artery were dark, and segmental aneurysmal dilatation was present. The base of the aneurysma] dilatation was successfully clipped, and the left A1 and A2 portion of the anterior cerebral artery wwas coated with fibrin glue. Following postoperative procedure and close monitoring, the course of the patient's recovery was steady and uneventful. Since cases of dissecting aneurysm of the anterior cerebral artery are rarely reported, the authors have discussed the possibility of surgical treatment when such cases arise.
