Tracheal stenosis in patients with double aortic arch: Regarding three cases

Abstract

Double aortic arch is a rare anomaly of the aortic arch, resulting from the persistence of the caudal dorsal aorta during embryogenesis. Clinical symptoms typically appear early, either in the neonatal period or within the first few months of life, and are characterized by respiratory and digestive manifestations. Precise diagnosis is made possible through thoracic CT angiography, which provides detailed visualization of the vascular structures. Surgery remains the only effective treatment to relieve tracheoesophageal compression. Through this case report of a 7-month-old infant presenting with tracheal stenosis due to a double aortic arch, we highlight the pivotal role of CT angiography in diagnosing this anatomical variant of the thoracic aorta.
