目的：探讨动脉瘤显微夹闭术后远隔部位小脑出血的临床表现、发生机制、治疗及预后。方法收集2013年9月~2014年12月发生的13例动脉瘤显微夹闭术后远隔性小脑出血的临床病例,分析其临床表现、治疗方法、预后及发生机制。结果13例患者术后表现为头痛10例,神志恍惚 3例,呕吐5例,一侧肢体肌力降低2例,昏迷 3例,麻醉苏醒延迟2例。13例患者中,有6例发生于双侧,7例发生于单侧,3例因出血多(超过10 mL),神志昏迷,行二期或者三期手术(颅内血肿清除术+去骨瓣减压术+脑室外引流术),10例经保守治疗出血全部吸收,13例经积极治疗均恢复良好,顺利出院,分析13例手术记录发现,术中均释放脑脊液降低颅内压操作。结论头痛、呕吐、麻醉苏醒延迟、意识水平下降及肢体肌力降低为动脉瘤显微夹闭术后远隔小脑出血的常见表现。一旦发生远隔部位小脑出血,及早发现,及早治疗,可以降低患者的病死率,改善患者的预后,术中颅内压的骤然改变可能是远隔部位小脑出血发生的机制。“,”Objective to investigate the clinical,imaging manifestation,mechanism,treatment and out-come of remote cerebellar hemorrhage (RCH)after aneurysms microsurgical clipping.Methods A retrospec-tive analysis was made on 13 cases of RCH after aneurysms microsurgical clipping from September 2013 to De-cember 2014 in neurosurgery department of Renmin Hospital Wuhan University.Clinical and imaging manifes-tation,treatment,outcome and mechanism were analyzed.Results Among 13 patients,headache in 10 cases, mind wanders in 3 cases,vomit in 5 cases,lower muscle strength in one side in 2 cases,unconscious in 3 cases, delay of recovery from general anesthesia in 2 cases.Among 13 cases,RCH happens in both sides in 6 cases and in single side in 7 cases.Cerebellar hemorrhage was more than 10ml and unconscious in 3 cases.3 cases were done secondary operation or three-stage operation.Blood was absorbed completely in 10 cases through conservative treatment.All 13 cases was good clinical recovery.Cerebrospinal fluid (CSF)was leaked in all 13 cases of RCH.Conclusions Headache,vomit,delay of recovery from general anesthesia,unconscious and lower muscle strength in one side are the most common clinical manifestation in RCH,Early detection and ear-ly treatment were important in improving the prognosis of RCH patients.The mechanism of RCH may be lea-king of the CSF which induce the intracranial pressure sudden decrease.
