摘要
目的 探讨椎动脉彩色多普勒对椎 基底动脉供血不足的诊断价值。方法 对 2 99例临床诊断为椎 基底动脉供血不足患者进行椎动脉彩色多普勒检查 ,观察多项血流参数。结果 椎动脉彩色多普勒超声诊断椎 基底动脉供血不足的阳性率为 5 6% (168/2 99)。阳性患者椎动脉内径狭窄 (P <0 .0 5 ) ;收缩期最大流速 (Vs) ,平均流速 (Vm )及舒张末期流速(Vd)较阴性患者明显减低 ,阻力指数 (RI)和搏动指数 (PI)增高 ,有显著性差异 (P <0 .0 1)。结论 结果表明椎动脉彩色多普勒及频谱多普勒超声对诊断椎
Purpose To explore the diagnostic value of the vertebral artery by color Doppler ultrasonography in detecting vertebrobasilar insufficiency. Methods Two hundred and ninety nine patients who were diagnosed vertebrobasilar insufficiency in clinic were examined by color Doppler ultrasonography in order to inspect their blood flow parameters. Results The positive rate of color Doppler ultrasonography was 56% (168/299) in diagnosing the vertebrobasilar insufficiency. The blood flow parameters and the inner diameters of the vertebral arteries were analyzed. Conclusion The findings of color Doppler ultrasonography will help the diagnosis of the vertebrobasilar insufficiency.
