Abstract:Objective To investigate the prognostic factors in interventional treatment of ruptured intracranial aneurysms. Methods The clinical data of 113 cases of ruptured intracranial aneurysms treated by endovascular treatment from January 2015 to June 2018 were retrospectively reviewed. The outcome was measured by the modified Rankin scale (mRs) and was dichotomized into favourable group (mRs 0 to 1) and unfavorable group (mRs 2 to 6). The potential factors for unfavorable outcome were evaluated by a univariate analysis and multivariate logistic regression analysis. Results Among the 113 patients, 83 (73%) patients had a favorable outcome, 30 (27%) patients had an unfavorable outcome. Univariate analysis indicated that age, Hunt-Hess grade, Fisher grade, timing of operation, hydrocephalus were significantly correlated with the prognosis (P < 0.05). Multivariate logistic regression analysis indicated that age [Ol ^ R = 1.065 (95% CI: 1.012, 1.121)], Hunt-Hess grade [Ol ^ R=9.497 (95% CI: 2.034, 44.345)], timing of operation [Ol ^ R=3.957 (95% CI: 1.242, 12.604)] and hydrocephalus [Ol ^ R=8.005 (95% CI: 1.552, 41.278)] were the factors affecting the prognosis for interventional treatment of ruptured intracranial aneurysms. Conclusions Age, Hunt-Hess grade, timing of operation and hydrocephalus can significantly affect the prognosis of the patients for interventional treatment of ruptured intracranial aneurysms.
