摘要目的 探讨大脑镰旁脑膜瘤的显微手术治疗的方法与技巧.方法 回顾性分析2004年5月至2009年6月,39例大脑镰旁脑膜瘤的临床资料.结果 根据骑跨大脑镰的位置选择手术入路,应用显微手术切除大脑镰旁脑膜瘤39例,其中34例肿瘤Simposon Ⅰ级切除,3例SimpsonⅡ级切除,1例SimpsonⅢ级切除,1例Ⅳ级.术后随访6～36个月,恢复良好,手术死亡1例,无肿瘤复发.结论 采用显微外科技术能提高骑跨大脑镰脑膜瘤的全切率,降低复发率,减少残死率;如果全切肿瘤可能带来重要的神经功能损害,应考虑分期手术或者残留部分肿瘤.手术切除程度可达Simpson Ⅰ～V级;良好的手术暴露、有效地控制术中出血、保护并妥善处理好上矢状窦和避免脑皮质损伤是提高手术疗效的关键因素.

abstractsObjective To evaluate the technique and artifice of microsurgery treatment for parasagittal meningiomas. Methods A retrospective analysis was performed on the clinical data of 39 cases of parasagittal meningioma between May 2004 and Jun 2009.Results According to the location straddling the falx choice surgical approach,39 cases of cerebral falx meningioma was treated by microsurgical. Simpson Grade I resection was achieved in 34(87.2%) cases,Grade Ⅱ in 3(7.7%) cases,Grade Ⅲ in 1 (2.6%) cases and Grade Ⅳ in 1 (2.6%) case. All patients were followed up for 6 months to 3 years. Only one patient died after the surgical operation and no patient suffered the recrudescence. Conclusion Application of microsurgical techniques can improve the saddle falx meningioma of the total removal rate, lower recurrence rate and reduce the rate of residual dead;if the whole tumor cut may bring significant neurological damage, should be considered part of staging surgery or residual tumor, and the degree of surgical resection of up to Simpson Ⅰ-V level;Good surgical exposure, effectively control the bleeding, protection and avoidance of damage to the cerebral cortex and superior sagittal sinus were important factors which increaseing the success rate of surgical resection.
