摘　　要：目的侧脑室脑膜瘤发病率低,手术入路亦有差别,特别在优势半球尤为明显。该文讨论侧脑室脑膜瘤最佳手术方案。方法通过13例侧脑室脑膜瘤手术治疗,使手术入路最大限度暴露肿瘤及供血血管,而不损害高级功能区;运用显微外科技术分块切除肿瘤。结果9例经项枕入路;2例经颞入路;1例经额入路;1例经胼胝体后入路。肿瘤全切除,无死亡;仅1例发生偏盲,其他病人症状均有不同程度改善。结论肿瘤大小、位置、供血影响手术入路的选择;顶枕入路适合侧脑室三角区脑膜瘤;运用显微技术,分块切除肿瘤可以减少术后并发症。Objective Lateral intraventricular meningiomas are rare tumors. The surgical approach sometimes is quite different. In this article the best choice of surgical approach is discussed. Methods The authors describe a series of 13 patients who underwent surgical treatment for lateral intraventricular meningiomas. They discuss the most influential factors in the choice of surgical approach, which must allow maximum exposure of the lesion and vascular feeding branches without damaging highly functional areas. In particular microsurgical techniques were applied to debulk the tumor by piecemeal removal.Results In nine patients the approach was via parieto-occpital;in 1 tran-seallosal;in 2 via temporal and in 1 tram-frontal. All tumors were totally removed, no patient died. Only 1 patient had newhemianopia. Other patients showed improvement of the symptoms. Conclusion The size, site and the vascularization of intraventricular meningiomas influence the choice of surgical approach. The parieto-oeeipital rout is particularly indicated to remove meningiomas of trigone, and using modem microsurgical technique can reduce the risk of complications.
