RESUMO
Objective To investigate surgical techniques and curative effects of stereotactic operation in the treatment of cerebellopontine hemorrhage.Methods Ten cases of cerebellopontine hemorrhage were treated by using the model FY-98 Ⅱ stereotactic apparatus.Under the guidance of CT scanning,three-dimension coordinates of the target that was located at the center of the maximum section of the hematoma were calculated.Then a catheter was introduced into the target for aspiration and urokinase irrigation under the guidance of the stereotactic system.Results The operation was successfully completed in all the 10 cases.The operation time was 50~80 min(mean,60 min) and the intraoperative blood loss,25~40 ml(mean,30 ml).Postoperatively,3 fatal cases were encountered because of brainstem function failure or upper digestive tract bleeding.The remaining 7 cases survived after operation and were followed for 3~12 months(mean,8 months).The postoperative hospital stay was 16~30 days(mean,21 days).Assessment with the Activities of Daily Living(ADL) scale showed grade Ⅱ in 3 cases,grade Ⅲ in 2,Ⅳ in 1,and vegetative state in 1.Conclusions Stereotactic surgery in the treatment of cerebellopontine hemorrhage has advantages of accurate location,high reliability,and satisfactory effect.
