Plain-English summary
A 10-week-old mixed-breed puppy was brought to the vet because it was frequently regurgitating food. X-rays and a special swallowing test showed signs of a possible vascular ring anomaly, which can cause problems with swallowing. During surgery, the vet found a left aortic arch but couldn't identify the exact cause of the obstruction at that time. Unfortunately, after the puppy passed away, a post-mortem exam revealed that the combination of the left aortic arch and a right ligamentum arteriosum was causing the esophageal blockage.

Abstract
A 10-week-old, mixed-breed dog was examined because of persistent regurgitation. Results of thoracic radiography and fluoroscopy of the esophagus, using a liquid suspension of barium sulfate, were suggestive of a vascular ring anomaly. During left lateral thoracotomy, a left aortic arch was identified, but the cause of the esophageal obstruction could not be determined. Results of endoscopic examination of the esophagus suggested a compressive lesion originating from the right side of the esophagus. An anomalous artery could not be identified on an aortogram. Post-mortem examination revealed a left aortic arch and right ligamentum arteriosum that were causing the esophageal obstruction.
