目的 分析颅后窝肿瘤术后早期急性脑积水的原因和防治对策。方法 临床资料回顾性分析。结果 该并发症的原因有肿瘤残留,小脑水肿、肿胀,颅内血肿、积液,颅后窝脑脊液通道粘连闭塞。结论 力争全切肿瘤,减少脑组织创伤,严密止血和疏通脑脊液通道,术后早期腰穿及抗脑水肿治疗,出现急性脑积水时先行侧脑室外引流并行病因治疗,必要时行内分流术。
Objective To analyze the causes and prevention and treatment of acute hydrocephalus in posterior cranial fossa tumors after operation. Methods Clinical data were retrospectively analyzed. Results The causes of the complications were residual tumor, cerebellar edema, swelling, intracranial hematoma, effusion, occlusion of CSF posterior cranial fossa. Conclusions The aim of this study is to strive for total tumor removal, reduction of traumatic brain injury, tight hemostasis and dredging of cerebrospinal fluid channels, early postoperative lumbar puncture and anti-brain edema treatment, concurrent side-to-side extracerebral ventricular drainage in case of acute hydrocephalus and shunting if necessary.
