This study was conducted to evaluate the overall outcome after intracranial aneurysm surgery operated at the Ajou University Hospital in 17-month period from June 1994 to October 1995. We operated 110 intracranial aneurysms from 96 patients. Two to fourteen months follow-up revealed 63 cases(57.3%) of good outcome, 14 cases(12.7%) of fair outcome, 14 cases(12.7%) of poor outcome, and 19 cases(17.3%) of dead outcome or discharge against advise. There was close relationship between the preoperative Hunt and Hess grade and outcome. The rate of good outcome in patients with Grade 1, 11, and III was 80.0%, 68.6%, and 65.0% respectively, while it was 24.4% in patients with Grade IV. There was no statistical difference of the rate of good outcome between patients operated at 0 to 3 days, 4 to 10 days, and 11 days or more after subarachnoid hemorrhage. The cause of poor outcome in order of frequency were initial hemorrhagic insult, hydrocephalus, intraoperative vascular occlusion, delayed ischemic deficits, and subdural hygroma.
