We here report the diagnosis and surgical outcomes of a cat and three dogs with persistent right aortic arch causing oesophageal enlargement. The chief complaint in all cases was regurgitation just after solid food intake. Barium oesophagographic examinations revealed enlarged oesophaguses cranial to the heart and strictures due to arteriosus ligament constriction of the oesophagus. Surgical correction was carried out using left fourth intercostal thoracotomy and severance of the ligamentum arteriosum. The cases frequently displayed residual clinical signs and still required modified diets after a mean follow-up period of 8.6 months, but owner satisfaction was acceptable.
