Variante compleja de arco aórtico de morfología bovina

The variations of the vessels that arise from the aortic arch are numerous, reported according to the literature consulted between 6 to 49% in various countries. Most variants are described as asymptomatic. However, some have been associated with significant symptoms and serious surgical problems, caused by the effects of compression or pressure that these variants exert on the trachea or esophagus. We present the case of a variant that we found no previous description in the literature, which was a trans surgical finding during a correction of a neonatal patient with a diagnosis of aortic coarctation.
