Coding Notes

While in the setting of a left aortic arch the arterial ligament is expected to be seen stretching from the concavity of the aortic arch to the pulmonary artery confluence, in the case of a right aortic arch one end of the ligament can normally be found at the base of the innominate (brachiocephalic) artery.
