Abstract
Introduction: Double aortic arch (DAA) is the most frequently encountered vascular ring malformation characterized by a complete encirclement of the trachea and esophagus by the aortic arch with a wide clinical spectrum. Objective: The aim of this study is to describe a case of DAA in adolesecents. Case Presentation: An 11-year-old boy was admitted for chronic productive cough which initially was diagnosed with pulmonary arterial hypertension. The final diagnosis was DAA which was established after chest computed tomography (CT) scan. Conclusion: Establishing a diagnosis of DAA in adolescents requires thorough understanding and clinical skills in performing diagnostic steps. The management of heart failure symptoms and other comorbidities is essential while preparing for its definite therapy.

Summary
Vascular ring is a congenital anomaly in which the trachea and esophagus (or its atretic remnant) are completely surrounded by vessels. Double aortic arch (DAA) is the most frequently encountered vascular ring malformation characterized by a complete encirclement of trachea and esophagus by the aortic arch. DAA has three types; right dominant aortic arch, left dominant aortic arch, and balanced-type aortic arch. Double aortic arch may be sufficiently tight to cause clinical symptoms or loose enough to be asymptomatic. (2015) Double Aortic Arch in Adolescence: A Case Report. Double aortic arch is usually diagnosed in infants with life-threatening respiratory symptoms due to severe trachea compression. When it is minimal, DAA may remain undiagnosed until adulthood. We report a case of a teenager with DAA which is diagnosed incidentally during a CT evaluation for chronic productive cough and pulmonary arterial hypertension
