dc.description.abstract	An 11 week-old intact female Springer Spaniel presented to the Community Practice Service at Cornell University for examination and routine puppy vaccinations. The patient’s history revealed that she routinely regurgitated after feedings. Physical examination revealed a palpable megaesophagus at the ventral, left caudal third of the neck. A vascular ring anomaly was strongly suspected. Thoracic and cervical radiographs, as well as computed tomography (CT) were performed to better understand the nature and cause of the megaesophagus. Imaging results revealed a persistent right aortic arch, a left ligamentum arteriosum and an aberrant left subclavian artery. Surgery was elected to correct the vascular ring anomaly. The ligamentum arteriosum was transected, and the patient's regurgitation eventually resolved. This case study will focus on the congenital anatomy of a patient with a persistent right fourth aortic arch as well as the diagnosis and treatment of the condition.	en_US
