Persistent double aortic arch in a dog (Canis familiaris): A case report. rev.udcaactual.divulg.cient. [online]. 2022, vol.25, n.2, e2310.  Epub 03-Ago-2022.

Persistent double aortic arch is a pathology characterized by embryonic vascularization anomalies, which can indirectly affect other systems such as the digestive and respiratory systems. The objective of this document is to report a case of persistent double aortic arch in a six-month-old Bull Terrier puppy. The patient was admitted for consultation due to frequent regurgitation and weight loss. The radiographic study revealed cranial esophageal dilation at the base of the heart, and a thoracotomy confirmed a persistent double aortic arch. Nutritional management was performed and subsequently, surgical correction of the vascular anomaly. This is the first case of an anomaly of this type in Colombia. It is concluded that surgical management focused on releasing the stenosing ring and recovering esophageal function are the therapeutic basis for this type of alteration.
