Double aortic arch is an important vascular ring anomaly, as the arches and atretic ligamentous cords surround and potentially compress the trachea and oesophagus. A clue as to the presence of double arch on barium swallow is the presence of focal oesophageal narrowing in both the AP and transverse directions.

Double Aortic Arch

Double aortic arch has been classified as type 1 (both arches patent) and type 2 (one arch atretic). The atretic arch is almost invariably the left. Type 2 double arches may be subclassified according to the position of the atresia. Subtype 1 the atretic segment is between ductus arteriosus and descending aorta; subtype 2 it is between left subclavian artery and ductus arteriosus; subtype 3 it is between left common carotid artery and left subclavian artery; and subtype 4 the atresia is between ascending aorta and left common carotid artery. In subtype 3 it is common for the left subclavian artery to arise from a diverticulum. The diverticulum has the same embryologic origin as that originally described by Burckhard Kommerell, and may reasonably be referred to as a Kommerell’s diverticulum.

Double aortic arch is an important vascular ring anomaly, as the arches and atretic ligamentous cords surround and potentially compress the trachea and oesophagus. A clue as to the presence of double arch on barium swallow is the presence of focal oesophageal narrowing in both the AP and transverse directions.
