| Abstract: | A 10‐year‐old dog weighing 3.4 kg presented with intermittent regurgitation. Esophagography revealed that the thoracic esophagus was compressed dorsally at the region of the fourth intercostal space and segmentally dilated from the second to third intercostal region. Three‐dimensional computed tomographic (CT) angiography confirmed a suspected vascular ring anomaly and also revealed multiple other vascular anomalies. These included aberrant right subclavian artery, absence of bilateral external jugular veins, right‐gastric caval shunt, and a completely duplicated caudal vena cava. Findings supported the use of thoracic CT angiography to rule out additional vascular malformations in dogs with suspected vascular ring anomaly. |
