Robotic division of an unusual variant of a right aortic arch.

Anomalies of the right aortic arch are rare. Right aortic arch with remnants of various components of the left aortic arch and ductus can create a vascular ring resulting in obstruction of the aerodigestive tracts. This case report describes the rare form of retroesophageal left innominate artery with ligamentum between the base of the subclavian artery to the pulmonary artery, and the first time management by the novel robotic approach.
