目的:探讨彩色多普勒与CTA在锁骨下动脉盗血综合征(SSS)临床应用价值。方法:25例临床怀疑锁骨下病变的患者,行彩色多普勒及CTA检查。结果:动脉硬化所致23例,大动脉炎所致2例。结论:彩色多普勒超声是筛选诊断SSS的经济、简便、无创、可靠的首选检查方法。可对绝大多数SSS做出病因学诊断。CTA检查可以对锁骨下动脉病变程度及类型以及对椎动脉病变做出明确诊断,2种方法联合应用对临床怀疑SSS患者进行筛查及临床治疗方案的制定有重要的指导作用。
Objective: To investigate the clinical value of color Doppler and CTA in subclavian steal syndrome (SSS). Methods: Twenty-five patients with suspected subclavian lesions underwent color Doppler and CTA examinations. Results: arteriosclerosis caused by 23 cases, 2 cases caused by arteritis. Conclusion: Color Doppler ultrasound is the first choice of economical, simple, noninvasive and reliable method for screening SSS. Etiology can be diagnosed in most SSS. CTA examination of subclavian artery lesions can be type and classification of vertebral artery disease to make a clear diagnosis of the two methods combined with SSS patients with clinical suspicion of screening and clinical treatment program has an important guiding role.
