目的分析比较14例锁骨下动脉盗血综合症患者锁骨下动脉、椎动脉和上肢动脉的血流动力学、频谱特点、狭窄程度与盗血关系,探讨如何提高锁骨下动脉盗血综合症的超声诊断符合率。方法应用Philips公司生产的iu22彩色多普勒超声诊断仪,回顾性分析我院检出的14例锁骨下动脉盗血综合症患者资料,选择高频探头探查颈动脉、椎动脉、锁骨下动脉远端及上肢动脉,选择低频小探头探查锁骨下动脉起始段。将其分为三型:完全型(椎动脉频谱完全呈反向),部分型(椎动脉频谱收缩期出现反向血流),隐匿型(椎动脉频谱收缩期出现切迹)。结果14例患者均由动脉粥样硬化引起,其中锁骨下动脉闭塞4例,均引起完全型盗血,狭窄10例,完全型盗血2例,部分型盗血5例,隐匿型盗血4例。结论彩色多普勒显像可对完全型动脉盗血综合症做出诊断,部分型及隐匿型动脉盗血综合症可辅助于脉冲多普勒和束臂试验以明确诊断。锁骨下动脉盗血与狭窄程度相关。对隐匿型盗血应充分认识椎动脉频谱早期特征性改变,从而避免漏诊的发生。
Objective To analyze and compare the hemodynamics, spectrum characteristics, stenosis and steal of the subclavian artery, vertebral artery and upper extremity arteries in 14 patients with subclavian artery steal syndrome, and to explore how to improve the ultrasonography of subclavian steal syndrome Diagnostic coincidence rate. Methods Using iu22 color Doppler ultrasonic diagnostic apparatus made by Philips Company, the data of 14 patients with subclavian artery steal syndrome detected in our hospital were retrospectively analyzed. The high frequency probe was used to probe the carotid artery, vertebral artery and subclavian artery End and upper extremity artery, select the low-frequency small probe to detect the beginning of the subclavian artery. Divided into three types: complete (vertebral artery spectrum was completely reversed), partial (reverse blood flow in the vertebral artery during systole), occult (notch in the vertebral artery during systole). Results All the 14 patients were caused by atherosclerosis, including 4 cases of subclavian artery occlusion, all of which caused complete steal and stenosis in 10 cases, complete steal in 2 cases, partial steal in 5 cases, concealed steal 4 example. Conclusion Color Doppler imaging diagnosis of complete carotid artery steal syndrome can be diagnosed. Partial and occult steal syndrome can be assisted by pulsed Doppler and beam-arm test to confirm the diagnosis. Subclavian artery steal and stenosis related. The stealth stealth should be fully aware of the early characteristics of vertebral artery spectrum changes in order to avoid missed diagnosis.
