Abstract: Objective：To investigate the application of the 3Dslicer software assisted softchannel puncture drainage in the treatment of senile hypertensive cerebral hemorrhage.Methods：The clinical data of 60 elderly patients with hypertensive cerebral hemorrhage were retrospectively analyzed，and were divided into 30 cases in the experimental group and 30 cases in the control group according to different preoperative localization methods.The control group was assisted by normal way，and the experimental group was assisted by 3Dslicer.And then drainage tube arrived at the predetermined location，clearance rate of hematoma，complications and prognosis of two groups were analyzed.Results：In the observation group，the success rate of the drainage tube reached the predetermined position was 90.0%，and the hematoma clearance rate on the third postoperative day ws（61.9±7.3）%.In the control group，the success rate of the drainage tube reached the predetermined position was 63.3%，and the hematoma clearance rate on the third postoperative day was（57.9±6.7）%.The difference was statistically significant（P<0.05）.The GOS score of the patients in the experimental group was 0 case in grade Ⅰ，1 case in grade Ⅱ，2 cases in grade Ⅲ，16 cases in grade Ⅳ，and 11 cases in grade Ⅴ.The GOS score in the control group was 1 case in grade Ⅰ，2 cases in grade Ⅱ，10 cases in grade Ⅲ，9 cases in grade Ⅳ and 8 cases in grade Ⅴ.The difference was statistically significant（P<0.05）.Conclusion：The application of the 3Dslicer software assisted softchannel puncture drainage for the treatment of senile hypertensive cerebral hemorrhage can improve the accuracy of puncture positioning and intracranial hematoma clearance.It can improve prognosis of patients.
