彩色多普勒超声诊断锁骨下动脉盗血综合征17例探讨

目的 探讨彩色多普勒超声诊断锁骨下动脉盗血综合征的应用效果.方法 超声检查17例经血管造影或数字减影血管造影确诊的锁骨下动脉盗血综合征患者,观测椎动脉频谱图的速度、形态、方向,对锁骨下动脉狭窄程度进行判断.结果 17例锁骨下动脉盗血综合征患者超声检查均作出正确诊断,左侧盗血者11例,右侧盗血者6例;锁骨下动脉狭窄程度:轻度4例,中度5例,重度8例,其椎动脉频谱形态分别为有切迹、正负双向及反向.结论 应用彩色多普勒超声可准确诊断锁骨下动脉盗血综合征,并能估测锁骨下动脉起始部狭窄程度.

Application of color Doppler ultrasonography in diagnosis of subclavian steal syndrome

Objective To evaluate the diagnosis value of subclavian steal syndrome(SSS)by color Doppler ultrasound.Methods Color doppler ultrasonography examinations were performed in 17 patients who had been identified as SSS according to the CTA(CT angiography)and DSA(digital substraction angiography).We used ultrasound to exam the direction and velocity of blood flow,the location and degree of stenosis.Results In all 17 cases,the diagnosis of SSS were achieved totally,11 cases in left side,6 cases in right side.Of all 17 cases,4 with mild stenosis,5 with moderate stenosis,8 with severe stenosis.Conclusion To observe the carotid artery,vertebral artery,subclavian artery,Color doppler ultrasonography can serve as diagnostic criteria in the degree of stenosis of SSS.
