彩色多普勒超声诊断锁骨下动脉盗血综合征的应用

目的分析锁骨下动脉盗血综合征(subclavian steal syndrome,SSS)的超声表现,旨在进一步提高彩色多普勒超声对此病的诊断价值。方法回顾性分析经彩色多普勒超声诊断有椎动脉返流的锁骨下动脉盗血综合征15例患者资料,并与脑血管造影的结果进行对比。结果 15例患者中,14例SSS患者首先经彩色多普勒超声确诊,漏诊1例,该例经脑血管造影后复查超声确诊。部分型SSS 4例(占26.7%),完全型SSS 11例(占73.3%)。SSS的病因为动脉粥样硬化狭窄所致14例,大动脉炎所致1例;病变血管为锁骨下动脉狭窄5例、无名动脉狭窄2例、锁骨下动脉闭塞或次全闭塞8例。结论彩色多普勒超声为锁骨下动脉盗血综合症诊断的首选影像学方法,完全型、部分型盗血与锁骨下动脉或无名动脉血管狭窄程度有关。

Diagnosis of subclavian steal syndrome by Doppler ultrasound

Objective To evaluate the imaging manifestations of subclavian steal syndrome and increase the diagnosis value of color Doppler ultrasound.Methods 15 SSS cases diagnosed by color Doppler ultrasound images and cerebral angiography were enrolled and analyzed.Results The accurately diagnosed cases by ultrasound were 14,the misdiagnosed cases were 1,all cases were confirmed by cerebral angiography.The partial group included 4 and the completed group included 11 cases.14 cases were caused by the stenosis of atherosclerosis and 1 case caused by Takayasu areritis.The subclavian stenosis was detected in 5 cases,anonymous artery stenosis in 2 cases and subclavian obstruction in 8 cases.Conclusion Doppler ultrasound examination is a easy and accurate method to diagnose subclavian steal syndrome,but we should pay more attention to the appearance of the Doppler spectrum of vertebral artery,and the degree of subclavian steal may be associated with the level of stenosis of anonymous artery and subclavical artery.
