目的：运用锁骨下动脉盗血综合征的二维及彩色频谱多普勒的声像图特点，探讨彩色多普勒超声对锁骨下动脉盗血综合征的临床诊断价值。方法应用二维及彩色多普勒超声对35例经DSA或临床确诊的锁骨下动脉盗血综合征患者进行检查，根据椎动脉返流情况将其分为3型：完全型（椎动脉频谱完全呈反向）、部分型（椎动脉频谱收缩期出现反向频谱）、隐匿型（椎动脉频谱收缩期出现切迹）。结果锁骨下动脉盗血综合征的主要原因是动脉硬化与大动脉炎。35例患者中，动脉硬化有33例、大动脉炎2例。病变在锁骨下动脉或无名动脉出现管腔狭窄或闭塞，在患侧椎动脉内出现逆向血流，根据椎动脉频谱特点划分完全型8例、部分型11例、隐匿型16例。结论锁骨下动脉盗血综合征的超声二维及多普勒频谱表现具有特征性，为锁骨下动脉盗血综合征病因及分型临床诊断提供依据。%Objective To investigate the effects of color Doppler ultrasonography in the diagnosis of SSS (Subclavian Steal Syndrome) based on its two-dimensional and color spectrum Doppler imaging features. Methods Two-dimensional and color Doppler ultrasonography examinations were performed in 35 patients who had been identiifed as SSS according to the DSA (Digital Substraction Angiography) results and clinical diagnosis. Then, all the patients were classiifed into 3 different types on the basis of their retrograde lfow in the vertebral arteries:the complete type (complete retrograde lfow in the systolic phase), the partial type (partial retrograde lfow in the systolic phase) and the insidious type (appearance of notches in the systolic phase). Results Atherosclerosis and aortoarteritis, as two major causes of the SSS, were found in 33 cases and 2 among 35 patients respectively. Vessel stenoses or occlusions were revealed in the subclavian or innominate arterial lesions with appearance of retrograde lfow on the diseased side of vertebral arteries. According to the spectral characteristics of the vertebral arteries, all the patients were classiifed into 3 different types:the complete type in 8 cases, the partial type in 11 cases and 16 cases of the insidious type. Conclusion The characteristics of two-dimensional and color Doppler ultrasonography in manifestations of SSS can serve as diagnostic criteria in the cause analysis and type-classifying clinical identiifcation of SSS.
