Abstract
Objective : To document surgical mortality and morbidity for the treatment of unruptured intracranial aneurysms, and to identify optimal treatment modalities, the authors reviewed and analyzed the surgical results. Methods : The authors reviewed 49 cases of unruptured intracranial aneurysm without a previous history of subarachnoid hemorrhage from March 1984 through December 2003. Unruptured intracranial aneurysms were categorized as asymptomatic and symptomatic, and operative results were assessed using the Karnofsky scale at 3 months postoperatively. Outcomes were defined as 'excellent' for a Karnofsky scale score of 100, 'good' for a score of $80{\sim}90$, 'fair' for $50{\sim}70$, 'poor' for $10{\sim}40$, or as 'death'. Excellent and good results were defined as a 'favorable' outcome and others as 'unfavorable' outcome. Results : Of the 49 study subjects, 45 had a favorable outcome and 4 an unfavorable outcome. Surgical mortality was 6.1% and surgical morbidity was 2.0% for all subjects. And the symptomatic group had more complications. Conclusion : There were no significant relationships between aneurysmal size, location, and preoperative symptoms with surgical results. And we believe that the reasons for morbidity and mortality are attributable to strokes, thus more attention should be paid to peri- and post-operative patients care with a focus on strokes prevention in the symptomatic group.
