彩超对锁骨下动脉窃血综合征32例的诊断分析

Value of color Doppler ultrasound in diagnosis of subsclavian steal syndrome

目的探讨锁骨下动脉窃血综合征的彩色多普勒超声特征和诊断价值。方法回顾性分析2010年1月至2014年3月经我院超声科诊断的32例SSS患者的声像图特征及血流动力学改变,并与DSA或MRA结果对照分析。结果 32例锁骨下动脉窃血综合征主要由动脉粥样硬化及大动脉炎引起,其中左侧锁骨下动脉病变21例,右侧锁骨下动脉病变11例,Ⅰ级窃血10例,Ⅱ级窃血9例,Ⅲ级窃血8例,Ⅳ级窃血5例。结论彩色多普勒超声是检测锁骨下动脉窃血综合征一种非常有效的无创性诊断方法。

Objective To discuss the value of color Doppler ultrosonography in diagnosis of subsclavian steal syndrome（SSS）. Methods A retrospective analysis of ultrasonic characteristic and hemodynamic changes was conducted in 32 patients with SSS who were admitted in our hospital from January 2010 to March 2014,and make contrast analysis with the results of DSA or MRA. Results There were 32 patients with SSS were caused by arteriosclerosis and aorto- arteritis,including 21 patients with left subclavian artery steal blood and 11 patients with right subclavian artery steal blood,10 patients had steal stage Ⅰ; 9 patients had steal stage Ⅱ; 8 patients had steal stage Ⅲ and 5 patients had steal stageⅣ. Conclusion Color Doppler ultrasonography is very helpful in diagnosis of.
