Radiographic manifestations of congenital anomalies of the aortic arch.

This article discusses congenital anomalies of the aortic arch. Many malformations of a left, right, or double aortic arch produce tracheal, bronchial, and esophageal compression and can be recognized on chest radiographs or esophagrams and confirmed by angiography, computed tomography, or magnetic resonance imaging. Other congenital lesions of the aortic arch are characterized by aortic obstruction and include supravalvular aortic stenosis, aortic arch interruption or atresia, and coarctation.
