Abstract: 

Background: Despite increasing acceptance of endovascular coiling for treating anterior communicating artery (ACoA) aneurysms, anterior circulation cerebral infarction (ACI) after embolization remains a limitation. With higher incidence, higher morbidity and higher mortality, it is one of the main factors influencing the ACoA aneurysms prognosis. Determining the risk factors leading to ACI after embolization will have clinical significance. Through retrospective case analysis, this study investigated the risk factors related to ACI after embolization in order to provide information to serve the clinical practice.
Materials and Methods: A retrospective review was performed of patients who had undergone coiling of ACoA aneurysms from 2008 to 2012. All patients had ruptured prior to the completion of embolization. Cases with acute stroke symptoms without alternative diagnoses after embolization were diagnosed as ACI. A total of 32 risk factors such as age, sex, hypertension, diabetes mellitus, modified Fisher grade, Hunt-Hess grade, ventricular hemorrhage, etc. were analyzed using univariate and logistic regression analysis.
Results: Univariate analysis showed that negative fluid volume balance (P=0.041 <0.05) and modified Fisher grade (P=0.049 <0.05) reached statistical significance, suggesting that they might be risk factors for ACI after embolization. Multiple logistic regression analysis showed that modified Fisher grade was significantly associated with ACI after embolization, suggesting that it was an independent risk factor (odds ratios (OR): 4.968, 95% confidence intervals (CI): 1.013-24.360, P=0.048).
Conclusion: Modified Fisher grade is an independent risk factor for ACI after embolization.
