Twenty-eight pa- tients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries （aneu- rysm clipping, hematoma evacuation and prophylactic hinged craniectomy） were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable out- comes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients＇ anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding （P〈0.05）. There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups （P〉0.05）. However, ingen- ious designed prophylactic hinged craniectomy efficiently reduced the patients＇ intracranial pressure （ICP） after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis ofMCAA oatients 19resenting with large SylH.展开更多
