【摘要】 目的 探讨多普勒超声成像检测锁骨下动脉盗血综合征的诊断价值并对其特有的超声表现，进行分析描述。方法 本文报道经彩色多普勒诊断并经造影或DSA证实的15例锁骨下动脉盗血综合征的患者。2例为无名动脉狭窄，13例为锁骨下动脉狭窄，观察存在狭窄的血管观察血流速度，下游血流变化走行方向，频谱形态有无异常表现。结果 二维图像检查，锁骨下及无名动脉起始端狭窄处斑块大小、回声强弱、长度、狭窄程度。将锁骨下动脉或无名动脉狭窄引起的患侧椎动脉反流分为四级：0级2例，1级3例，2级9例，3级1例。结论 彩色多普勒超声检测锁骨下动脉盗血综合征，准确率高，追踪病变部位扫查连续性好，测量准确，可作为检测此病的首选方法之一。

    【Abstract】 Objective To evaluate the diagnostic value of Doppler ultrasonic imaging in detecting subclavian steal syndrome， and to analyze the ultrasonic appearance of subclavian steal syndrome.Methods 15 subclavian steal syndrome patients， 2 were innominate artery stenosis and 13 were subclavian artery stenosis， diagnosed by arteriography or DSA were detected by color Doppler ultrasound. The inspection items included blood flow rate in stenostic vessel ......
