Prognostic Factors for Anterior Cerebral Artery Aneurysms: A Single-Center Series

Objective: The aim of the present study is to summarize the characteristics of anterior cerebral artery aneurysms and to explore the prognostic factors of microsurgical clipping treatment for anterior cerebral artery aneurysms. Materials and Methods: A total of 90 anterior cerebral artery aneurysms (ACAAs) are reviewed from January 2000 to July 2019. Patients are categorized into good outcome group and poor outcome group according to Glasgow outcome scale scores. Multiple factors, including clinical characteristics and aneurysms' characteristics, are evaluated to identify the independent risk factors associated with prognosis of ACAAs. Results: This analysis reveals that in the ACAAs database the number of SAH (P=0.01), high H-H grade (P<0.001) and high Fisher grade (P<0.001) are correlated with prognosis of ACAAs. Finally, age (P=0.007, odds ratio=1.124, 95% CI: 1.033-1.223) and Hunt-Hess (grade III-V, P=0.022, odds ratio =59.77, 95% CI: 1.794-1991.298) are found to be independent risk factors for prognosis. Conclusions: The age and high Hunt-Hess grade seem to be important factors affecting the prognosis of ACAAs.
