The arteria lusoria is an aberrant right subclavian artery that passes dorsally between the esophagus and spine after branching off from the aortic arch.- https://www.sciencedirect.com/science/article/pii/S001651070...
(B) Axial black blood sequence MR image shows a left sided aortic arch (LA) with an aberrant right subclavian artery (arrow) coursing posterior to the esophagus. This is considered a normal variant, the luxury artery. - https://books.google.pt/books?id=VJvuCQAAQBAJ&pg=PA326&lpg=P...

Mit dem zusammengesetzten Begriff Normvariante (englisch normal variant) wird in der Medizin alles das bezeichnet, was nicht üblicherweise, sondern lediglich bei einem kleineren Teil einer vergleichbaren Bevölkerungsgruppe auftritt. Das Wort setzt sich zusammen aus „Norm“ im Sinne eines vereinbarten oder festgelegten Standards (Normwert). - https://de.wikipedia.org/wiki/Normvariante
Intracranial arterial variants, of which there are many, are collectively common. Their clinical significance may be variable but knowledge and recognition of these variants is fundamental, especially if surgical or endovascular treatments (e.g. for acute stroke, aneurysms or other vascular pathologies) are being considered. - https://radiopaedia.org/articles/intracranial-arteries-varia...

The anatomical variation was identified as being an arteria lusoria . - https://www.degruyter.com/downloadpdf/j/cipms.2014.27.issue-...
This abnormality was accidentally discovered in a computed tomography examination of a 69-year old male patient. The examination showed that the artery went towards the neck posteriorly from the trachea.The anatomical anomaly was interpreted as being an arteria lusoria . – the same link
Arteria lusoria may cause dysphagia, and in rare cases, it may be the reason for the esophagus lumen narrowing, which can occur at any age – idem
