Coding Notes

When the arterial connection is between the ascending and descending aorta, it is often associated with coarctation of the aorta. This malformation may be distinguished from a double aortic arch by the lack of arch vessels arising from it and by establishing that the accessory vessel and the aortic arch lie on the same side of the tracheo-oesophageal axis. Although this malformation has been termed a “persistent fifth aortic arch”, the use of this term is in dispute.
