A Clinical Study Of The Relationship Of Timing To Outcome Of Surgery For Ruptured Cerebral Aneurysms

objective: To investigate the relationship between the timing of surgery for intracranial ruptured aneurysms and the clinical outcome. Methods: A retrospective analysis of 105 patients with ruptured cerebral aneurysms, in which were 56 male and 49 female, undergoing treatment was made. Each patients clinical grade according to Hunt& Hess classification was assessed at admission. Early surgery was performed on 33 patients and delayed surgery on 72 patients. Evaluation was made by Glasgow outcome scale at the discharge. Result: Early surgery group has 33 patients. Thirty one patients had excellent or goodoutcomes, the overall mortality rate was 6.1%, the surgical mortality rate was 0%, and two patients (6.1%).occurred clinical vasospasm. There were 26 patients in Grade â…  ~ â…¡, and twenty five patients had excellent or good outcomes, and one patient with multiply aneurysms died of rebleeding at 6 day after operation. There were 6 patients in Grade â…¢. and five patients had excellent or good outcomes, and one patient was died of initial hemorrhage. One patient in Grade â…£, no one in Grade â…¤. There were 72 patients in the late surgery group, and sixty two of them had excellent or good outcomes. Overall mortality rate was 6.9%, and the surgical mortality rate was 0%, and the rebleeding rate was 4.2%. There were 17 patients (23.1%) occurred clinical vasospasm. There were 61 patients in Grade â…  ~ â…¡ , and twenty 56 patients had excellent or good outcomes. Three patients died of rebleeding in the waiting period. There were 9 patients in Grade â…¢. and six patients had excellent or good ou(?)comes. No one died. There were 2 patients in Grade â…£ ~ â…¤ , and all of them died of initial hemorrhage. Conclusion: There were no statistically significant differences in good outcome and mortality rate between early and late surgery group, which explained early surgery can n(?) increased surgical morbility and mortality rate. Timing of surgery was n(?) mater cause of outcome in Grades. â…  ~â…¢. Early surgery can reduce the clinical vasospasm rate. The rebleeding rate and clinical vasospasm m(?)rbility rate were less than late surgery group, but it can not analysis by statistics.
