To present details of surgical management of an unusual vascular ring anomaly in two German Shepherd littermates. Study Design

Clinical case report. Study Population

Three-month-old intact male and female German Shepherd littermates. Results

In each dog, the esophagus was obstructed by a vascular ring comprised of the left aortic arch, an anomalous patent right ductus arteriosus, and the pulmonary artery ventrally. Surgical treatment consisted of dividing and oversewing the patent right ductus arteriosus. Neither dog has clinical signs of esophageal disease one year after treatment. Conclusion and Clinical Relevance

This vascular ring anomaly should be considered a possibility in any young dog with esophageal obstruction and a machinery murmur.
