Objective To describe the treatment of persistent right aortic arch (PRAA) in dogs with combined ligamentum arteriosum (LA) transection and esophageal diverticulum resection. Animals Three client owned dogs. Study Design Short case series. Methods Medical records were reviewed for clinical signs, diagnostic procedures, surgical treatment, post‐operative therapies including medications and feeding regime, outcomes, and follow‐up imaging. Results Esophageal resection was performed using a thoracoabdominal (TA) stapler with suture overlay. All dogs recovered well from surgery and did not experience any peri‐ or post‐operative complications. The last follow‐up was performed between 64 and 1004 days post‐operatively. In all cases, regurgitation resolved and did not recur in any dogs. No dogs required medical therapy or dietary modifications. In two cases, follow‐up imaging was performed that revealed marked improvement of esophageal dilation. Conclusion Resection of esophageal diverticulum secondary to PRAA utilizing a TA stapler with suture overlay was technically feasible and did not seem associated with early or late complications.
