显微手术切除脑中央区双侧镰旁巨大脑膜瘤

目的 探讨显微外科技术在脑中央区双侧镰旁巨大脑膜瘤手术中的应用.方法 采用跨中线骨瓣、条状硬脑膜瓣、向对侧牵引上矢状窦和经单侧纵裂切除双侧肿瘤等显微手术技术,切除16例脑中央区双侧镰旁巨大脑膜瘤.结果 肿瘤均为Simpson I级切除,术后症状较术前改善13例,与术前相同3例,无手术死亡;术后随访6个月-5年,全部患者均未见肿瘤复发.结论 应用显微外科技术能够较好地避免过度牵拉脑叶,减少功能区脑皮层和重要回流静脉的损伤,消除了上矢状窦对大脑镰的"屋檐效应",有利于肿瘤的暴露和完全切除.

Abstract：

Objective To investigate microsurgical techniques in bilateral falcine meningiomas of central gyrus region surgery. Methods Sixteen patients with bilateral falcine meningiomas in central gyrus region were treateded with a series of microsurgical techniques, including midline - crossing craniotomy,dural cut in a strip fashion with a flap based on the superior sagittal sinus, retraction of the superior sagittal sinus toward the opposite side and an ipsilateral interhemispheric fissure approach. The clinical data and prognosis was summarized. Results Simpson I grade removal was achieved in all patients. The neurological functions were improved in 13 cases, unchanged in 3 cases postoperatively. There was no postoperative death. The follow up period of patients ranged from 6 to 60 months and no tumor recurrence was observed. Conclusion Application of minimally microsurgical techniques can be better to avoid over -stretch the brain leaves, reduce significant damage to eloquent cerebral cortex as well as venous reflux,and eliminate the "eaves effect" of the superior sagittal sinus to the falx in favor of exposure and complete resection of tumor.
