目的应用彩色多普勒超声评价正常人头颈部分别向左右转动后基底动脉(BA)血流动力学参数.方法应用彩色多普勒超声对62例正常人在俯卧位低头以及头颈部分别向左右转动90°后三种姿势下,观察BA血流,并对其血流动力学指标进行对比分析.结果 ①三种姿势下BA的检出率:俯卧位低头为89%,头颈部左转为84%,头颈部右转为81%,三种姿势下BA血流的显示率比较差异无统计学意义(P>0.05).②椎动脉颁段内径:左侧大于右侧[左侧(0.34±0.06)cm对右侧(0.32±0.05)cm,P<0.05].③BA血流速度(收缩期速度、舒张期速度):头颈部左转后与俯卧位低头BA血流速度差异有统计学意义(P<0.05),而右转后与左转以及低头姿势下BA血流速度差异无统计学意义(P>0.05),三种姿势下阻力指数差异无统计学意义(P>0.05).结论彩色多普勒超声对BA检出率高,能够准确清晰地显示不同姿势下BA的血流动力学情况,提示正常人头颈部向左转时对BA血流有影响,对研究椎-基底动脉系血流动力学有着重要的临床意义.

Objective To evaluate the basilar artery hemodynamical changes in cervical rotation and ventral flexion by color Doppler flow imaging(CDFI). Methods Basilar artery blood flow were detected during cervical With cervical right lateral,left lateral rotation and ventral flexion, the detection ratio of basilar artery by ultrasound were 89% ,84% ,81% respectively. There were no difference in statistics between the detction ratio of three kinds during cervical flexion,peak systolic velocity(PSV) and end-diastolic velocity(EDV) decreased apparently during left lateral rotation,which did not change during right lateral rotation. No changing was found with resistant index between the three kinds of cervical position. Conclusions The hemodynamic changing of basilar artery during cervical rotation and flexion could be detected by CDFI accurately,which might be useful in clinical study.
