椎动脉型颈椎病的彩色多普勒超声诊断

目的 :观察椎动脉型颈椎病的高频彩色多普勒表现和血流动力学变化。方法 :应用彩色多普勒超声诊断仪 (高频探头 ,频率 7～ 10MHz)检测 138例椎动脉型颈椎病患者 (颈椎病组 )的椎动脉 (VH)内径 (D)、血流速度 (V)和血流量 (Q)、阻力指数 (RI)和搏动指数 (PI) ,观察其形态结构、并与 10 0例 (对照组 )进行对照分析。结果 :颈椎病组VA的V(除平均血流速度外 )、D ,Q ,RI,PI与对照组比较差异有显著性 (P <0 0 1)。结论 :高频彩超显示的椎动脉形态和血流参数变化为临床评价椎动脉型颈椎病治疗效果提供了有价值的依据

High frequency color duplex sonography in cervical spondylosis

Obiective To observe the morphological structure and hemodynamic changes of the vertebral artery in cervical spondylosis by high frequency color duplex sonography. Methods We measured 138 cases of cervical spondylosis at the vertebral artery with a 7 5～10 MHz probe of high frequency color duplex sonography, to determine morphological changes, Diameter(D), Velocity(V), Blood flow volume, and Resistance index(RI) and (PI). A controlled analysis was performed at the same time. Results The measurement showed that the vertebral arteries of the patients bent more severely than the controlled group. There was a significant difference between the two groups (P<0 01) in Diameter (D), Velocity (except mean velocity), Blood flow volume, and resistance index (RI)and (PI).Conclusion High frequency color duplex sonography has provided clinlical judement on morphological and blood flow dynamic parameter changes of the vertebral artery with a valuable objective basis.
