高频彩色多普勒超声结合束臂试验在锁骨下动脉窃血综合征诊断中的价值

Value of High-Frequency Color Doppler Ultrasonography Combined withTourniquet Test in Diagnosis of Subclavian Steal Syndrome

目的:探讨经高频彩色多普勒超声结合束臂试验在检测锁骨下动脉窃血综合症(SSS)中的意义与价值。方法:回顾性分析我院自2006年6月至2012年6月来我院就诊的经CDFI检查并结合DSA血管造影、核磁共振血管造影(MRA)及CT血管造影(CTA)等相关检查明确诊断的67例锁骨下动脉窃血患者,对锁骨下动脉、无名动脉、椎动脉及上肢动脉的二维图像、彩色多普勒、脉冲多普勒图像以及行束臂试验后的血流动力学变化进行分析。结果:67例SSS患者中动脉粥样硬化型63例,多发性大动脉炎4例,完全性窃血15例,部分性窃血45例,隐匿性窃血7例。结论:高频彩色多普勒超声结合束臂试验能显著提高锁骨下动脉窃血综合征尤其是不完全性窃血及隐匿性窃血的确诊率。

Objective： Discuss the significance and value of high-frequency color Doppler ultrasonography combined with tourniquet test in diagnosis of subclavian steal syndrome. Methods： Carry out the retrospective analysis for 67 patients who were confirmed to suffer subclavian steal syndrome after receiving the CDFI inspection, DSA, magnetic resonance angiography （MRA） and CT angiography （CTA） and relevant checks in our hospital from June 2006 to June 2012 and conduct the analysis for the two-dimensional images, color Doppler images and pulse Doppler images of subclavian artery, innominate artery, vertebral artery and upper artery, as well as the post-tourniquet test hemodynamic changes. Results：Among 67 SSS patients, 63 patients suffer the carotid atherosclerosis and 4 patients suffer the Takayasu arteritis, including 15 complete steal cases, 45 partial steal cases and 7 secret steal cases. Conclusion：The high-frequency color Doppler ultrasonography combined with tourniquet test can significantly improve the diagnosis rate for subclavian steal syndrome, especially for the incomplete steal syndrome and secret steal syndrome.
