(1.广州中医药大学第二临床医学院,广东广州 510405;2.广东省中医院脑血管病中心神经五科,广东广州 510120)[摘 要] 目的 分析脑动脉狭窄的病变特点及侧支循环的模式,探讨脑动脉闭塞或严重狭窄时侧支循环代偿建立的情况与患者神经功能的关系。方法 回顾性分析362例缺血性脑血管病患者资料,全部患者均接受DSA检查。对脑血管狭窄病变的特点及侧支循环与神经功能缺损的关系进行分析。结果 362例缺血性脑血管病患者中,334例共存在716处脑动脉狭窄病变;其中单纯颅内动脉狭窄143例(42 81%),单纯颅外动脉狭窄84例(25 15%),颅内、颅外动脉均存在狭窄107例(32 04%);单纯前循环病变173例(51 80%),单纯后循环病变58例(17 37%),前、后循环联合病变103例(30 84%)。300处颅外动脉狭窄中,颈内动脉颅外段狭窄185处(61 67%),椎动脉颅外段狭窄96处(32 00%);416处颅
