摘要 目的探讨经颅多普勒超声检查(TCD)对老年椎基底动脉供血不足(VBI)的临床应用价值。方法回顾性分析经临床诊断≥60岁的VBI的患者100例(观察组)的TED记录椎动脉(VA)、基底动脉(BA)的血管峰值收缩期流速(Vs)、舒张末期流速(Vd)、平均血流速度(Vm)及搏动指数(PI)等检查资料,并与同期≥60岁100例健康体检正常人群(对照组)TCD检查结果进行比较分析。结果观察组TCD检查异常79例(79.0%),对照组TCD检查异常11例(11%);观察组VA、BA的Vm、Vs、Vb的血流参数均数明显低于对照组;PI均数高于对照组,2组比较差异有统计学意义(P<0.05)。结论 TCD检查对老年VBI患者的诊断敏感性较高,并可为动态观测病情进展及客观评估疗效提供依据。
