Abstract： 目的 讨颈动脉狭窄患者血管反应性的改变.方法 选择80例缺血性脑卒中患者(缺血性脑卒中组),应用彩色多普勒超声检测患者屏气期间颈内动脉的最大平均血流速度,计算呼吸抑制指数(BHI),并与同期住院的60例非缺血性脑卒中患者(对照组)进行比较.结果 缺血性脑卒中组颈动脉轻度狭窄29例,中度狭窄8例,重度狭窄5例,闭塞3例,正常35例.对照组颈动脉轻度狭窄5例,中度狭窄2例,无重度狭窄或闭塞,正常53例.缺血性脑卒中组颈动脉中重度狭窄患者屏气期间颈内动脉最大平均血流速度为(24.22±8.55)cm/s,BHI为1.17±0.37,均低于对照组颈动脉正常者[分别为(36.46±9.72)cm/s和1.39±0.94],差异均有统计学意义(P<0.05).结论 颈动脉狭窄患者血管反应性明显下降.彩色多普勒超声显示颈动脉效果良好,可作为颈动脉狭窄的筛选工具.
