彩色多普勒超声在锁骨下动脉盗血综合征诊断中的临床价值

目的探讨彩色多普勒超声诊断锁骨下动脉盗血综合征(SSS)的临床价值。方法对64例均被数字减影血管造影(DSA)或血管CT造影(CTA)确诊的SSS患者,进行二维、彩色血流显像(CDFI)及频谱多普勒观察颈动脉、椎动脉、锁骨下动脉、及上肢动脉的血流方向、速度、频谱形态,并根据狭窄程度分组。结果 64例SSS患者中,动脉硬化62例,多发性动脉炎2例,左侧42例,右侧22例,轻度狭窄14例,中重度狭窄26例,闭塞24例,52例锁骨下动脉起始部狭窄,12例无名动脉狭窄。结论彩色多普勒超声能准确估测SSS患者的血管狭窄部位及程度,明确病因,具有较高的临床价值。

Objective To study the clinical value of color doppler ultrasound in diagnosis of subclavian steal syndrome（SSS）. Methods Observe the blood fow direction, speed and spectrum morphology of carotid vertebral subclavian and upper extremity arteries via the 2D color Doppler fow imaging （CDFI） and spectral Doppler of 64 cases which are diagnoized of SSS, then divide them into groups according to the degree of stenosis. Results 64 cases of SSS patients, hardening of the arteries in 62 cases, 2 cases of Takayasu arteritis, 42 cases on the left side, right side in 22 cases,14 cases of mild stenosis, moderate to severe stenosis in 26 cases, occlusion in 24 cases, 52 cases of subclavian artery stenosis, 12 cases of innominate artery stenosis. Conclusion Color Doppler ultrasound can accurately estimate the location and extent of blood vessel stenosis in patients with subclavian artery steal blood and clear causes, so it has a high clinical value.
