Abstract

We analyzed the overall surgical results in 100 patients with intracranial aneurysms operated in Presbyterian Medical Center during the period from June 1990 to December 1993. Preoperatively, all patients were in Hunt and Hess grades I-III. Overall outcomes revealed 83 patients(83%) of good outcome, 10 patients(0%) of fair outcome. 3 patients(3%) of poor outcome, and 4 patients(4%) of dead outcome. The outcome was worse if surgery was performed in the 4 to 10 day post- bleed interval(P<0.05) and there was no statistical difference of the rate of good outcome between the parients operated at 0 to 3 days, and 11 day more after subarachnoid hemorrhage. In good grade patients, surgical trauma rather than delayed ischemic deficit was considered as the major cause of unfavorable outcome of aneurysm surgery. Intermedia to period operation increased the chance of postoperative delayed ischemic deficit. Systemic complications and vasospasm were the major causes of dead outcome in the oldaged patients.
