摘要 目的:通过数字减影全脑血管造影(DSA)检查,观察短暂性脑缺血发作(TIA)患者脑血管狭窄或闭塞的部位及程度。方法:采用DSA对90例TIA患者进行全脑血管造影检查,观察颈总动脉、颈内动脉和椎基底动脉颅内、颅外段血管有无狭窄以及狭窄部位,并判断血管狭窄程度。结果:本组90例,血管造影正常18例、烟雾病2例、血管狭窄或闭塞70例。血管狭窄或闭塞70例中,颈动脉系统受累36例(51.4%),椎基底动脉系统受累12例(17.1%),锁骨下动脉受累2例(2.9%),颈动脉系统和椎基底动脉系统同时受累有20例(28.6%)。颈动脉系统中以颈内动脉起始段和大脑中动脉M1段受累最为常见,椎基底动脉系统中以椎动脉开口处受累最为常见。结论:脑血管狭窄是TIA的主要病因,DSA可以明确TIA患者血管狭窄的部位及程度,对了解TIA的病因、指导有效治疗起重要作用。
