Complex Cervical Aortic Arch With Hypoplasia: A Simple Solution to a Complex Problem.

We report a rare case of a 6-year-old boy with a complex right-sided cervical aortic arch, with retroesophageal hypoplastic transverse arch, left subclavian artery arising from the Kommerell diverticulum of the descending aorta, and a vascular ring formed by the ductus ligament. An extraanatomic ascending-to-descending aorta bypass was done through a median sternotomy along with division of the ductus ligament, without any complications and good results.
