锁骨下动脉盗血综合征(SSS)的定义是在锁骨下动脉狭窄的情况下,同侧椎动脉的血流逆转。这里,我们描述了一例罕见的左SSS患者,其伴有显著的左锁骨下动脉狭窄,与左椎动脉(LVA)的异常起源直接来自主动脉弓有关.通过这个案子,作者试图强调使用多普勒超声的重要性和正确的技术,以及侵入性血管造影在了解LVA起源异常患者锁骨下盗血机制中的重要性。
The subclavian steal syndrome (SSS) is defined by the reversal of flow in the ipsilateral vertebral artery in the setting of subclavian artery stenosis proximal to its origin. Here, we describe a rare case of left SSS with significant left subclavian artery stenosis associated with anomalous origin of the left vertebral artery (LVA) directly from the aortic arch in a patient presenting with signs of vertebrobasilar insufficiency and resolution of symptoms following angioplasty. Through this case, the authors try to emphasize the importance and the correct technique of using Doppler ultrasonography, and the importance of invasive angiography in understanding the mechanism of subclavian steal in patients with anomalous LVA origin.
