【摘要】 【目的】分析不同影像检查在诊断及治疗锁骨下动脉盗血综合征中的作用。【方法】3例锁骨下动脉狭窄合并冠心病的患者经临床及颈动脉B型超声多普勒、磁共振血管造影以及动脉血管造影而确诊。2例分别经肱动脉及冠状动脉植入锁骨下动脉支架及冠状动脉支架。【结果】比较3种检查方法显示:其中颈动脉B型超声多普勒简单易行,能明确血流的方向、血管内血流的流速,可用于术前的筛选和术后的复查。磁共振血管造影(MRA)可明确狭窄的部位与程度,并可建立三维结构,可作为术前的参考。数字减影动脉造影(DSA)一般在手术时进行,可明确狭窄的部位和程度,当发现有盗血综合征存在时,一定要做健侧动脉血管造影,以明确血流的方向和血流流向对侧的途径。在狭窄严重或完全狭窄时,经肱动脉途径成功比例较高。如肱动脉搏动过于微弱,难以定位时可行肱动脉切开。【结论】三种方法各有特点,可互为补充,但最后确诊及指导治疗DSA造影是必不可少的。更多还原

【Abstract】 【Objective】To analyze different imaging examination in the diagnosis and therapy of subclavian steal syndrome.【Methods】Three cases with subclavian steal syndrome were diagnosed by Doppler ultrasound,magnetic resonance angiography(MRA),and digital subtraction angiography(DSA),the subclavian artery stent and coronary artery stent were implanted in 2 cases respectively.【Results】The Doppler ultrasound was easy to do,and could show the direction of the blood flow.MRA could define the site and degree of the stenosis,and establish three-dimensional structure.But DSA was necessary for the diagnosis and therapy.【Conclusion】Three methods have the advantages of themselves,they can combine each other,but DSA is necessary for diagnosis and treatment.更多还原
