显微手术治疗窦镰旁脑膜瘤的疗效分析

目的 探讨显微手术治疗窦镰旁脑膜瘤的手术技巧和临床疗效。方法 回顾性分析2019年5月至2021年7月显微手术治疗的42例窦镰旁脑膜瘤的临床资料。结果 术中发现肿瘤突入窦腔内4例，与窦壁外层紧密联系8例，位于窦镰旁30例。Simpson分级Ⅰ级25例，Ⅱ级15例，Ⅲ级2例。无手术死亡病例。术后随访3~12个月，未见肿瘤复发。结论 窦镰旁脑膜瘤周围组织结构复杂，手术风险高。制定合理的手术计划、术中进行精细操作，有助于减少并发症，提高手术疗效。

Surgical outcomes of parasagittal sinus and parafalx meningiomas

Objective To investigate the surgical techniques and clinical efficacy of microsurgery for the patients with parasagittal sinus and parafalx meningioma. Methods The clinical data of 42 patients with parasagittal sinus and parafalx meningioma who were treated by microsurgery from May 2019 to July 2021 were analyzed retrospectively. Results The tumor was found to protrude into the sinus cavity in 4 patients, closely connected with the outer layer of the sinus wall in 8, and located beside the falx in 30. Simpson grade Ⅰ was achieved in 25 patients, grade Ⅱ in 15, and grade Ⅲ in 2. There were no operative deaths. The follow-up (range, 3~12 months) showed no tumor recurrence. Conclusions The tissue structures around parasagittal sinus and parafalx meningiomas are complex and the operation risk is high. Reasonable surgical planning and good intraoperative skills are helpful to reduce the postoperative complications and improve the surgical outcomes.
