中央区矢状窦旁脑膜瘤的显微手术治疗

Microsurgical Treatment for Parasagittal Meningiomas at the Central Cortex

目的探讨中央区矢状窦旁脑膜瘤手术的技巧。方法应用显微手术治疗中央区矢状窦旁脑膜瘤32例。利用肿瘤与脑组织之间的蛛网膜界面,囊内或分块切除肿瘤,注意保护中央沟静脉、其他引流静脉和正常脑组织,妥善处理受累的矢状窦。结果SimpsonⅠ级切除17例(53.1%),Ⅱ级切除11例(34.4%),Ⅲ级切除4例(12.5%)。无手术死亡。并发症:脑水肿及梗死2例,予手术减压;10例术后偏瘫加重,其中8例1~6周逐渐恢复,2例一侧肢体不全瘫痪。术后21例随访3个月~5年,2例Ⅱ级切除、2例Ⅲ级切除者术后1~3年复发。结论充分的术前影像学评估,采用显微外科技术切除中央区矢状窦旁脑膜瘤,处理矢状窦,避免脑皮质、中央沟静脉和其他引流静脉的损伤,是提高矢状窦旁脑膜瘤手术全切率和手术疗效的重要因素。

Objective To study the surgical skills for parasagittal meningioma at the central cortex. Methods A total of 32 patients with parasagittal meningiomas at the central cortex were treated with microsurgery. Through the arachnoid interfaces between the tumor and the brain tissue, the tumor was removed piece by piece. The vein of central sulcus, other draining veins, and normal brain tissues were protected, and the involved sagittal sinus was appropriately treated. Results Simpson Ⅰ, Ⅱ, and Ⅲ grades resection w...
