彩色多普勒超声诊断锁骨下动脉盗血综合征的临床价值

目的：探讨彩超对锁骨下动脉综合征（SSS）的检查技巧及临床诊断价值。方法选取我院2010年8月-2013年6月间确诊为锁骨下动脉盗血综合征患者53例，进行颈动脉、椎动脉及锁骨下动脉二维超声及彩色多普勒超声检查，分析血流动力学特点。结果53例患者中动脉粥样硬化38例，多发性大动脉炎15例。根据椎动脉频谱特点划分为隐匿型SSS共17例，患侧椎动脉频谱收缩期出现切迹；部分型SSS共26例，患侧椎动脉收缩期血流反向；完全型SSS共10例，患侧椎动脉血流收缩及舒张期均反向。结论彩超对于早期筛查SSS具有明显优势，并可对大多数SSS进行病因学诊断。

Diagnostic Value of Color Doppler Ultrasound in Subclavian Artery Steal Syndrome

Objective To investigate the examination skills and diagnostic value of Color Doppler ultrasound in subclavian Artery Steal Stndrome（SSS）.Methods 23 cases confirmed SSS were selected during 2010August to 2013 year in June in our hospital,Two-dimensional and color Doppler ultrasonography were given on Carotid artery,vertebral artery and subclavian artery,and analyse the hemodynamic characteristics.Results 20 patients with atherosclerosisa and 3 patients with Takayasu＆#39;s arteritis in 23 cases.Accord-ing to the spectral characteristics of the vertebral arteries,all cases were classified into 3 different types：the insidious type in 7cas-es, systolic notch in the ipsilateral vertebral artery;the partial type in 11 cases, the ipsilateralvertebral artery systolic flow reversal;the complete type in 5 cases, the psilateral vertebral artery systolic and diastolic all reverse. Conclusion Color doppler ultrasound has obvious advantages inearlyscreening for SSS,and can dive the etiological diagnosis for most SSS.
