中央回区附近脑膜瘤的显微手术方法

目的 探讨中央回区附近脑膜瘤的显微手术方法及治疗效果.方法 应用显微手术治疗中央回区矢状窦旁、大脑镰旁脑膜瘤71例,术中注意保护中央沟静脉、代偿回流静脉,妥善处理受累的矢状窦.结果 SimpsonⅠ级切除45例,Ⅱ级切除17例,近全切除9例,术后出现偏瘫5例,无手术死亡病例.42例随访1～5年,未见复发.结论 手术过程中以保护中央区皮层功能为总原则,同时注意保护中央沟静脉及失状窦,有利于减少脑重要功能区的损失,改善患者预后.

Abstract：

Objective To discuss the efficacy of microsurgery in meningioma around central gyrus region. Methods Seventy-one patients with parasagittal and parafalcine meningioma around central gyrus region were treated with microsurgery technique. Special attention was paid on the vein of central sulcus and other compensative venous pathways to protect them from being damaged; the affected sagittal sinuses were duly handled. Results Simpson grade Ⅰ resection was achieved in 45 patients (63.4%) ,grade Ⅱ in 17 (23.9%), near total resection in 9 (12.7%), and hemiparalysis happening in 5patients, and no patient died. Fourty-two patients was followed up for 1 to 5 years without recurrence.Conclusion choosing the strategy of preserving the function of central gyrus region and improving the microsurgical technique in treating meningioma around central gyrus region can decrease the injuries to significancant domain of the brain.
