摘要
目的探讨彩色多普勒超声(CDU)在锁骨下动脉窃血综合征(Subclavian Steal SyndromeSSS)应用价值,分析锁骨下动脉窃血综合征椎动脉血流频谱特征及流速与锁骨下动脉狭窄程度的关系。方法回顾性分析我院自2006年9月至2009年9月来我院应诊的患者42例锁骨下动脉窃血患者,进行锁骨下动脉、椎动脉、颈动脉及上肢动脉的二维图像及彩色多普勒和脉冲多普勒分析。结果彩色超声显示椎动脉血流方向完全逆流28例,部分逆流10例,血流速度明显减慢4例;直接显示锁骨下动脉内膜增厚38例,斑块形成36例,闭塞性改变2例,另外4例虽锁骨下动脉起始部显示欠清晰,但依据椎动脉血流提示锁骨下动脉窃血。结论患侧椎动脉、锁骨下动脉、上肢动脉的二维图像、彩色多普勒血流显像、脉冲多普勒有典型特征,结合临床,可明确诊断锁骨下动脉窃血。根据椎动脉反流程度来推测锁骨下动脉或无名动脉的狭窄程度,彩色多普勒超声诊断此病具有重要的意义。
Objective To evaluate the application of color Doppler ultrasound（CDU） in the subclavian steal syndrome（Subclavian Steal Syndrome SSS）and analyse the relationship between blood flow velocity and its spectral characteristics and stenosis of various degrees in subclavian steal syndrome.Methods A retrospective analysis of 42 cases of patients with Subclavian Steal Syndrome from September 2006 to September 2009in my hospital with the help of two-dimensional images and Color Doppler and Pulsed Doppler.Resuts The color Doppler shows the direction of vertebral artery blood flow completely counter-current in 28 cases;some of reflux in 10cases;blood flow has slowed significantly in 4 cases;direct indication of the subclavian artery intimal thickening in 38 cases;plaque formation of 36 cases;occlusive changes in 2 cases.In another four cases,the initial part is unclear,but the blood flow tell us it.Conclusion Combining two-dimensional images,blood flow imaging of color Doppler,the typical characteristics of pulsed Doppler with clinic,Subclavian Steal Syndrome can be diagnosed confirmly.According to the degree of backward flow,color Doppler ultrasound also play important role for the diagnosis of artery stenosis.
