锁骨下动脉窃血综合征的彩色多普勒超声分析

Retrospective Analysis of Subclavian Steal Syndrome with Color Doppler Flow Imaging

目的探讨锁骨下动脉窃血综合征的彩色多普勒特征,评价不同程度的锁骨下动脉窃血与锁骨下动脉起始部或无名动脉狭窄的关系。方法回顾性分析经相关检查及临床确诊的34例锁骨下动脉窃血综合征患者肱动脉、桡动脉、椎动脉、颈动脉、锁骨下动脉及无名动脉二维超声、彩色多普勒特点以及狭窄程度与窃血的关系。结果锁骨下动脉窃血综合征患侧肱动脉、桡动脉及椎动脉彩色多普勒均有异常改变。结论椎动脉返流程度与锁骨下动脉狭窄程度呈正相关,隐性窃血见于病变复杂及病情严重者。

Objective between retrograde flow of different degrees. Methods To explore the features of subclavian steal vertebral artery and proximal subclavian A total of 34 patients with subclavian steal syndrome and to evaluate the correlation artery or innominate artery stenosis in syndrome were diagnosed via correlated examination and clinical.The examined arteries included brachial, radial, vertebral,carotid, subclavical and innominate arteries. The ultrasonic features of 2-dimensional and color Doppler flow imaging （CDFI） and the correlation between the degree of the stenosis and retrograde flow of vertebral arteries were analysed. Results The Ipsilateral brachial, radial and vertebral arteries had abnormal changes in all the cases on CDFI.Conclusions The degree of retrograde flow in vertebral artery has positive relation with vertebral artery stenosis. The retrograde steal phenomena occurred usually in patients with complicated and severe pathogenetic conditions.
