后颅窝肿瘤术后早期脑积水

目的 分析后颅窝肿瘤术后早期脑积水的原因并提出预防措施。方法 对18例后颅窝肿瘤术后早期脑积水患者的临床资料进行回顾性分析。结果 本组18例术后24h内一般情况均良好，之后随即出现神志淡漠、嗜睡、头痛、呕吐等，CT检查见脑积水。在施行包括侧脑室外引流术在内的综合治疗后，16例痊愈，2例死亡。结论 术后小脑水肿、颅内血肿、肿瘤残留等可能是导致该并发症的主要原因。预防措施包括术中规范的显微神经外科操作以尽量保护脑组织、严密止血、术后综合治疗等。

Early hydrocephalus after surgery for posterior cranial fossa tumors

Objective To analyse the possible reasons of early hydrocephalus after surgery for posterior cranial fossa tumors, and put forward the preventive messures against this complication.Methods Clinical data of 18 cases of early hydrocephalus after surgery for posterior cranial fossa tumors were analysed retrospectively.Results All the patients were in good state within 24 hours after surgery, but a series of symptoms, such as disturbance of consciousness, headache and vomiting, occurred. CT scanning showed hydrocephalus. After the comprehensive treatment including ventricular drainage, 16 patients were healed.Conclusion Post-operative cerebellar edema, intracranial hematoma or hydrops, residual tumor, might be the possible reasons of this disease. Preventive messures against this complication might include the following points: brain tissures should be well protected during microsurgery operations, hemostatic procedures should be well done, and also post-operative comprehensive treatment.
