椎基底动脉供血不足的彩色多普勒超声诊断

Vertebrobasilar in-Sufficiency on color Doppler Ultrasound Diagnosis

目的 :探讨彩超对椎基底动脉供血不足患者血流动力学变化特点及诊断价值。方法 :用惠普 HP85 0 0彩超检测 6 6例椎基底动脉供血不足患者椎基底动脉血流速度、动脉指数、血管结构及走行 ,并与对照组对比分析。结果 :患病组血流速度 (Vm )减慢、阻力指数 (RI)增高、血管内径缩小 (与对照组比较 P<0 .0 1) ,30 .0 %血管迂曲走向异常。结论 :二维超声、脉冲多普勒及彩色像相结合技术为临床诊断椎基底动脉供血不足提供有价值的客观指标 ,是一种可靠的无创检查方法。椎基底动脉供血不足多由椎动脉狭窄所致。

Objective To invesitigate the effect of CDFI in the diagnosis of VBI.Methods 66 patients with VBI were examined to detect and measure the bolld flowsignals the structure of blood vessels and the indicntion of arteriae.Results the blood flow signal was decreased,the resistance index was indreased,the inner diameterof vessel was minified and 30 % abnormality of vessel trace.Conclusion The mulfunctionof CDFI in the diagnosis of VBI provided valuble objectiove indication and no invasion methods VBI was caused by vertebrobasilar stenosis.
