A 3-month-old girl presented with respiratory distress and stridor requiring intubation and assisted ventilation. Bronchoscopy demonstrated extrinsic compression on the distal trachea. A Computed Tomography (CT) of thorax confirmed a double aortic arch (Figure 1
). Echocardiography showed no associated abnormalities.

Figure 1. (Left) A pre-operative CT thorax with 3D reconstruction of the heart and aorta shows left (LAA) and right (RAA) aortic arches of similar diameter, forming a complete vascular ring around trachea and left main bronchus. A patent ductus arteriosus (PDA) is not visualized, but a knuckle on the distal left arch corresponding to its position was noted. (Right) The post-operative CT thorax shows very good separation between the divided left and right arches, relieving the airways compression.
