摘要 目的:分析颈内动脉系统TIA患者的脑动脉狭窄部位,证实颈动脉系统TIA患者脑动脉狭窄存在高发段(部位),为颈内动脉系统TIA患者选择合适的检查及治疗手段提供帮助。方法:对75例颈内动脉系统TIA发作患者行主动脉弓及全脑血管造影,回顾性分析颈内动脉系统TIA患者脑动脉狭窄的高发部位。结果:75例TIA患者共发现超过50%责任病变狭窄126处,发生狭窄的频次及好发部位依次为:CCA9处狭窄、E-ICA35处、I-ICA26处、MCA38处、ACA18处;其中几个部位的狭窄占的比率较高:颈动脉系统:颈总动脉分叉处和颈内动脉起始处共发现狭窄29处,占23.01%;颈内动脉虹吸部共发现狭窄18处,占14.28%;大脑中动脉主干共发现狭窄21处,占16.67%;大脑中动脉分叉处共发现狭窄8处,占6.35%;以上几个部位的狭窄占所有ICA狭窄的60.31%。结论:颈内动脉系统TIA患者有以下几个部位发生狭窄的几率较高,分别为颈总动脉分叉处和颈内动脉起始部、颈内动脉虹吸部、大脑中动脉主干、大脑中动脉分叉部,为颈内动脉狭窄的高发段。
