RESUMEN CORTO - SHORT SUMMARY

A 5-month-old, intact female, Labrador retriever was referred to our hospital with chronic regurgitation. There was high suspicion of persistent right aortic arch (PRAA) seen on an esophagram showing cranial esophageal dilatation. Computed tomography (CT) was performed confirming the diagnosis of PRAA. Thoracoscopy with concurrent esophagoscopy and selective intubation was performed to break down the ligamentum arteriosum (LA) and to dissect the fibrotic tissue constricting the esophagus. No complications befell during the procedure. An esophagram following surgery was performed and revealed an improvement of the cranial esophageal dilatation compared to the esophagram prior to surgery. Although after surgery there was still cranial esophageal dilatation the dog has not had any regurgitation episode.

In contrast to previous studies this is considered a success due to the results in the quality of life of our pacient. Due to the advantages of thoracoscopy assisted by esophagoscopy in contrast to intercostal thoracotomy, this technique should be considered for surgical treatment of PRAA.

The use of thoracoscopy assisted by esophagoscopy should be considered for surgical treatment of persistent right aortic arch due to the advantages it has showed compared to intercostal thoracotomy.
