第四脑室室管膜瘤的显微外科治疗

Microsurgery for Ependymomas in the Fourth Ventricles

目的总结第四脑室室管膜瘤的显微外科治疗经验。方法回顾性分析2001年5月至2006年5月我院收治的15例第四脑室室管膜瘤患者的临床资料。结果肿瘤全切11例,次全切除4例,无手术死亡,术后发生并发症5例。术后短期(半年)随访,其中恢复良好11例,改善3例,恶化1例。结论枕下经小脑延髓裂入路能够充分暴露第四脑室底部,减少术后小脑并发症。

Objective To summarize experience in the microsurgically treating ependymomas in the fourth ventricles. Method The clinical data of 15 patients with ependymomas, including the clinical manifestations, tumor size, extent of removal of the tumors, and postoperative complications, was analyzed retrospectively. All the patients underwent microsurgery for the ependymomas in our department from May, 2001 to May, 2006. Results Total removal of tumors was achieved in 11 cases, and subtotal removal in 4. No patients died from the operation. The postoperative complications occurred in 5 cases. Following up for half a year showed that good recovery was achieved in 11 cases, improvement in 3, and aggravation in 1. Conclusion The microsurgery through suboccipital transcerebellomedullary fissure approach can sufficiently expose the floor of the fourth ventricle and decreased the postoperative complications related to cerebellum.
