摘要 目的:探讨利用数字减影血管造影(DSA)技术,观察后循环短暂性脑缺血发作(TIA)患者脑血管的形态变化,进一步为该病的诊断及治疗提供参考。方法:观察对象为临床诊断为后循环短暂脑缺血发作性的92例患者,全部进行全脑血管DSA检查,分析血管形态异常的类型、部位以及受累血管数目。结果:后循环TIA患者92例,病变137侧,其中前循环(颈动脉系统)病变l5侧(11%);后循环(椎-基底动脉系统)病变122侧(89%),累及两条或两条以上血管3l例(34%),以椎动脉合并其他血管狭窄最为常见。椎-基底动脉系统病变中椎-基底动脉狭窄或闭塞39侧(28%),大脑后动脉狭窄或闭塞13侧(9%),后循环变异59侧(43%)。结论:后循环狭窄和变异可能是中老年人后循环TIA的主要原因。
