摘　　要：目的探讨锁骨下动脉盗血综合征的彩色多普勒超声表现及诊断价值。方法对30例锁骨下动脉盗血综合征患者的椎动脉颅外段、锁骨下动脉、无名动脉进行超声检查,观察其超声表现及血流动力学变化,并做束臂试验。结果 30例患者中隐匿型6例(占20.0%)、部分型14例(占46.6%)、完全型10例(占33.3%),超声诊断符合28例(占93.3%),漏诊2例(占6.7%,均为隐匿型)。结论彩色多普勒超声检查能提示锁骨下动脉盗血的病变部位、程度及病因,同时有效评价血流动力学改变,是临床诊断SSS的首选影像学检查方法。Objective To evaluate the diagnostic value of color Doppler ultrasonography in subclavian steal syndrome （SSS）. Methods The sonographic appearance and the hemodynamic data of extracranial vertebral, subclavian, innominate arteries in 30 patients with SSS were displayed with color Doppler ultrasonography, and do tourniquet test. Results The insidious group included 6 cases （20.0%）, the partial group included 14 cases （46.6%） and the completed group included 10 （33.3%）. The accurately diagnosed cases by ultrasound were 28 （93.3%）. The misdiagnosed cases were 2 （6.7%, all in the insidious group）. Conclusion Color Doppler ultrasonography can be prompted to subclavian steal the lesion site, extent and causes, while effectively evaluate the hemodynamic changes in the clinical diagnosis of SSS is the preferred method of imaging examination.
