Abstract:
Double aortic arch is an exceedingly rare congenital vascular anomaly, and its association with anomalous origins of the vertebral arteries is even more uncommon. Enhanced computed tomography revealed a double aortic arch with the left common carotid artery, left vertebral artery, and left subclavian artery originating from the left arch, and the right common carotid artery, right vertebral artery, and right subclavian artery arising from the right arch. To our knowledge, this is the first report of a double aortic arch with six distinct vessels originating from both arches. Enhanced CT should be considered in double aortic arch patients to identify such anomalous origins of branch arteries.
