目的探讨彩色多普勒超声对锁骨下动脉盗血综合征(SSS)的诊断价值。方法回顾性分析81例SSS患者超声特点、病因、血流动力学改变及合并疾病与盗血的关系。结果 81例SSS患者锁骨下动脉起始或无名动脉管腔均为不同程度的狭窄或闭塞,其中动脉硬化者79例,大动脉炎1例,肿瘤癌栓1例。依据椎动脉频谱特点分为隐匿型25例,部分型39例,完全型17例。结论 SSS的彩色多普勒超声检查具有特征性,并且彩色多普勒超声可动态评价SSS的血流动力学改变,为临床诊断提供可靠依据。
Objective To investigate the diagnostic value of color Doppler ultrasound in subclavian steal syndrome (SSS). Methods A retrospective analysis of 81 cases of SSS patients with ultrasound characteristics, etiology, hemodynamic changes and the relationship between the disease and steal the blood. Results 81 cases of SSS patients with subclavian artery or unnamed artery lumens were varying degrees of stenosis or occlusion, including atherosclerosis in 79 cases, 1 case of arteritis, tumor thrombus in 1 case. According to the characteristics of vertebral artery spectrum were divided into occult type in 25 cases, partial type in 39 cases, complete type in 17 cases. Conclusion The color Doppler ultrasound examination of SSS is characteristic, and the color Doppler ultrasound can dynamically evaluate the hemodynamic changes of SSS, providing a reliable basis for clinical diagnosis.
