Hajjar, F. Aassouani, H. Bennani, M. Haloua, N. El Bouardi, B. Alami, My. Y. Alaoui Lamrani, M. Maaroufi, M. Boubbou Abstract: The double aortic arch is a rare anomaly of vascular malformations of the aorta, which develops in embryonic life. The clinical picture is usually silent, if not dominated by respiratory and/or digestive signs, particularly laryngeal dyspnea or dysphagia in newborns, infants and young children. Thoracic angioscan is the gold standard for diagnosis and treatment. The treatment is only surgical. We report the case of a 5-month-old infant, admitted for acute dyspnea with laryngeal stridor, whose interrogation reveals repetitive bouts of cyanosis during feedings, and the clinical examination reveals sibilant rales on auscultation. The radiological explorations carried out, in particular; a thoracic CT scan showed a double aortic arch joined by a thin ligament associated with a retroesophageal diverticulum encircling and stenosing the tracheo-esophageal axis. The baby was referred to a cardiovascular surgery department for possible surgical management. Objective: This clinical case challenges us to keep in mind embryological vascular malformations of the type of double aortic arch as an etiology, although rare, of acute dyspnea with laryngeal stridor in the newborn.
