How is a persistent right aortic arch treated?
Treatment is surgical. The constricting ring is separated. Surgery should be performed early, before permanent damage has occurred to the lining of the esophagus due to distension. Postoperative care involves feeding a liquid diet with gradual introduction of frequent small meals. In some dogs occasional regurgitation may persist. Breeding advice Affected individuals and their parents should not be used for breeding. Siblings should only be used after careful screening. If any affected offspring are born, breeding of the parents should be discontinued.
