摘要
目的探讨第四脑室肿瘤的显微手术方法。方法2000年1月～2003年6月我院对29例第四脑室肿瘤采用显微手术治疗,5例因肿瘤侵犯上蚓,瘤体接近皮层部采用小脑蚓部入路,余24例均经小脑延髓裂入路,显微手术切除肿瘤。结果肿瘤全切除23例,次全切除6例。术后并发症:上消化道出血2例,小脑缄默征1例,第四脑室血肿1例,远隔部位硬膜外血肿1例,呼吸不规则1例。19例随访3～12个月,平均5.5月,肿瘤无复发。结论术前正确判断肿瘤性质及其基底部所在位置,选择适当的手术入路,熟练掌握第四脑室的显微解剖是手术成功的关键。
Objective To explore the microsurgical treatment of the fourth ventricular tumors. Methods A total of 29 cases of the fourth ventricular tumors were given microsurgical treatment from January 2000 to June 2003 in this hospital. In 5 cases the tumor was located close to the cortex with the superior vermis involvement and the microsurgical operation was performed through the cerebellar vermis. The remaining 24 cases underwent microsurgical resection of tumor through the cerebellomedullary fissure approach. Results A total resection was achieved in 23 cases, and a subtotal resection in 6 cases. Postoperative complications included 2 cases of hemorrhage of the upper digestive tract, 1 case of tourism, 1 case of hematoma of the fourth ventricular, 1 case of epidural hematoma remote from surgical site, and 1 case of irregular breath. Follow - up surveys in 19 cases for 3- 12 months （ mean, 5.5 months） revealed no tumor recurrence. Conclusions Preoperative proper differentiating characters of tumors, clarifying the position of tumors＇ basal part, selecting appropriate surgical approach, and understanding microanatomy of the fourth ventricular are the key to successfully complete the procedure.
