抄録

12 patients with anterior choroidal artery (AchoA) aneurysms were operated on between 1980 and 1987 at Keio University. Seven patients had ruptured AchoA aneurysms. In addition to this group, there were 5 cases of unruptured AchoA aneurysms which were found during procedures for ruptured aneurysms at other locations (2 cases), for brain tumor (2 cases) or for TIA (1 case).<BR>Postoperative occlusion of the AchoA occurred in 3 patients who deteriorated as a result of the surgical procedure. In one case, the AchoA could not be identified during operation and might have been occluded by the clip. In another case. there was delayed occlusion of the AchoA 3 days after the operation. The presumed cause of this complication might be a kinking of the vessel due to displacement or rotation of the clip. In the last case, the clip caused stenosis of the AchoA and subsequently infarction during a period of vasospasm. We believe that the clip should be placed at a short distance from the origin of the AchoA in order to avoid unexpected stenosis or even occlusion.
