Abstract
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.

Resumo
Em alguns casos, a artéria subclávia direita pode se originar da porção esquerda do arco aórtico. Esse vaso aberrante é conhecido como artéria lusória. Para chegar em sua região, essa artéria passa posteriormente ao esôfago, e pode ser, portanto, causa de uma doença conhecida como disfagia lusória, desencadeando sintomas desconfortantes. A artéria lusória está frequentemente associada com outras anomalias, como o nervo laríngeo não recorrente e o tronco bicarotídeo, assim como pode estar em associação com aneurismas, defeitos cardíacos congênitos e até síndromes genéticas. Durante dissecação cadavérica de rotina, foi observada a presença dessa artéria em um cadáver do sexo masculino fixado em uma solução de formalina a 10%. O objetivo deste trabalho é relatar a variação conhecida como artéria lusória e trazer destaque para seus aspectos embriológicos, clínicos e cirúrgicos.
