摘要 目的总结脑动脉夹层的临床特点,影像学特征。方法回顾性分析我科近5年来经脑血管造影确诊的45例脑动脉夹层的特点,分析位置分布、临床表现、夹层形态的特征。结果脑血管造影共发现48处脑动脉夹层,其中双侧颈动脉夹层1例,双侧椎动脉夹层2例。夹层主要位于颅内段,占87.5%。前循环13例患者中,69.2%为非扩张性病变;后循环32例患者中,71.9%为扩张性病变。76.9%的前循环夹层表现为脑梗死,而65.6%的后循环夹层表现为蛛网膜下腔出血。根据夹层形态分析,81.5%的扩张性改变表现为蛛网膜下腔出血,而77.8%的非扩张性改变表现为脑梗死。结论脑动脉夹层多位于颅内段,后循环的夹层多为扩张性改变,多表现为蛛网膜下腔出血;前循环的夹层多为非扩张性改变,更多表现为脑梗死,血管造影有助于诊断。
