Abstract： 目的探讨蝶骨嵴脑膜瘤血液供应的特点及其术前栓塞对手术切除的意义.方法52例蝶骨嵴脑膜瘤患者中,发生于右侧者31例,左侧者21例;52例患者全部行DSA造影,30例患者行颈外系统供血动脉栓塞治疗,栓塞治疗后5～7 d行手术切除.结果 (1)脑膜瘤的占位改变可导致邻近周围脑血管的异常改变.(2)52例患者中,单纯由颈外动脉系统分支供血的有11例,颈外动脉分支和颈内动脉分支双重供血的29例,单纯由颈内动脉系统供血的12例.(3)30例行肿瘤供血动脉栓塞的患者中,25例采用明胶海绵颗粒栓塞,5例采用丝线栓塞.栓塞的颈外供血动脉主要为:脑膜中动脉18例,脑膜中动脉与脑膜副动脉同时被栓塞者10例.栓塞后肿瘤染色明显减轻者20例,染色消失者5例,肿瘤染色减轻不明显者5例.(4)栓塞后行手术切除的30例患者中,24例被完整切除,而未行栓塞的22例患者中,仅10例被全切除,二者统计学上差异具有显著性意义(χ2=3.86,P<0.05).结论蝶骨嵴脑膜瘤的术前造影和栓塞有利于肿瘤的完整切除.
