A Double Lane for a Better Circulation: Percutaneous Duplication of the Thoracic Aorta in a Child.

Aortic arch interruption or atresia consists in a complete loss of anatomical and luminal continuity between the ascending and descending thoracic aorta. It is usually diagnosed in newborn babies but may also be present in young children, adolescents, adults and elderly patients. In these cases, it can be congenital or more frequently acquired. This latter type of aortic arch atresia is a challenge, and surgery is usually the treatment of choice. Percutaneous approaches are also possible today. We describe a case of percutaneous aortic arch reconstruction in a 9-year-old boy.
