The right subclavian artery may originate from the left portion of the aortic arch. This aberrant vessel is known as the arteria lusoria. Its course to its usual site runs behind the esophagus, which may cause a disease known as dysphagia lusoria, responsible for symptoms of discomfort. This artery is often associated with other anomalies, such as the non-recurrent laryngeal nerve and the bicarotid trunk, and with diseases such as aneurysms, congenital heart defects, and even genetic syndromes. During routine dissection of a male cadaver fixed in 10% formalin solution, an arteria lusoria was found. This article reports the variation and discusses its embryological, clinical and surgical aspects.
右锁骨下动脉可能起源于主动脉弓的左侧部分。这种异常血管被称为迷走动脉。它到达其正常位置的走行位于食管后方，这可能导致一种称为迷走动脉性吞咽困难的疾病，引发不适症状。这条动脉常与其他异常情况相关，如非返喉神经和双颈动脉干，还与诸如动脉瘤、先天性心脏缺陷甚至遗传综合征等疾病有关。在对一具固定于10%福尔马林溶液中的男性尸体进行常规解剖时，发现了一条迷走动脉。本文报告了这种变异情况，并讨论了其胚胎学、临床和手术方面的问题。
