DUQUE PARRA, Jorge Eduardo; ESTRADA PANTOJA, Sanny Lorena  and  MONTENEGRO A, Álvaro. Aortic Arch Variant in Human Cadaver. Int. J. Morphol. [online]. 2012, vol.30, n.4, pp.1458-1460. ISSN 0717-9502.

It shows an anatomy variant of the aortic arch projecting to the right of the trachea and esophagus that generated in-flow proximal left common carotid artery, right common carotid artery, right subclavian artery and finally a left subclavian artery subsequently derived from the descending aorta. It also shows involvement of circulating air volume decreased to and from the tracheal bronchus due to compression to reduce its diameter.

Keywords : Anatomical variation; Aortic arch; Trachea.
