后颅窝肿瘤切除术后早期脑积水的成因及处理分析

目的 分析后颅窝肿瘤术后早期脑积水的成因并提出临床对策。方法对18例后颅窝肿瘤术后1周内并发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检查为脑积水。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。结论术后小脑水肿或肿胀、颅内血肿或积液、肿瘤残留等可能是导致该并发症的主要原因。预防措施包括术中尽量保护脑组织、严密止血、术后综合治疗等。

The reasons and preventive messures of 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 rnessures 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 duainage, 16 patients were healed. 2 cases died. Conclusions Post-operative cerebellar edema,intraeranial hematoma or hydrops, residual tumor, might be the possible cause of this disease. Preventive messures against this complication might include protecting brain tissues during operations, hemostasis and comprehensive treatment after operations.
