Objective To investigate the prognostic related factors in the patients with ruptured intracranial aneurysm treated by surgical treatment and their clinical significance .Methods The medical record data in 218 cases of ruptured aneurysm treated by operative treatment were performed the retrospective analysis ,including th egeneral data ,Hunt‐Hess grade on admission ,surgical procedure ,etc .The patient′s prognosis situation adopted the Glasgow outcome scale(GOS) as the evaluation standard when dis‐charge from hospital .Firstly the possible factors were performed the single factor analysis ,then the factors with statistic signifi‐cance in the single factor analysis were performed the multiple factors logistic regression analysis .Results The single factor analy‐sis indicated that the age ,Hunt‐Hess grade on admission ,hypertension ,operation mode ,CT Fisher grading and symptomatic vaso‐spasm were significantly correlated with the prognosis ( P < 0 .05) .The multiple factors analysis indicated that age ,Hunt‐Hess grade on admission ,symptomatic vasospasm ,CT Fisher grading were the independent risk factors affecting the prognosis of patients (P< 0 .05) .Conclusion The patients′ age ,Hunt‐Hess grade on admission ,symptomatic vasospasm and CT Fisher grading can sig‐nificantly affect the prognosis of the patients with ruptured intracranial aneurysm after surgical treatment .Paying attention to the predictive value of these predictors has important clinical significance to reduce the postoperative mortality rate and disability rate in the patients with ruptured intracranial aneurysm .
