目的分析彩色多普勒超声对锁骨下动脉盗血综合征的诊断价值。方法回顾性分析39例彩色多普勒超声诊断为锁骨下动脉盗血综合征并经数字减影血管造影(DSA)证实的患者的超声影像学资料。结果所有患者均经彩色多普勒超声确诊,其中30例由动脉粥样硬化所致,9例由大动脉炎所致。Ⅰ期盗血4例,Ⅱ期盗血25例,Ⅲ期盗血10例,病变主要发生在锁骨下动脉(SA)起始部或无名动脉(IA)。结论彩色多普勒超声能准确判断锁骨下动脉盗血综合征的病因、病变部位及盗血程度,具有重要的诊断价值。
Objective To analyze the diagnostic value of color Doppler ultrasound in subclavian steal syndrome. Methods A retrospective analysis of 39 cases of color Doppler ultrasound diagnosis of subclavian steal syndrome and confirmed by digital subtraction angiography (DSA) in patients with ultrasound imaging data. Results All patients were confirmed by color Doppler ultrasound, of which 30 cases were caused by atherosclerosis and 9 cases were caused by aortic arteritis. Stage Ⅰ stolen blood in 4 cases, stage Ⅱ steal in 25 cases, stage Ⅲ steal in 10 cases, the lesion occurred mainly in the beginning of the subclavian artery (SA) or anonymous artery (IA). Conclusion Color Doppler ultrasound can accurately determine the cause of subclavian steal syndrome, the lesion site and the degree of steal, has important diagnostic value.
