Failures in embryological processes are one of the main causes of vascular anomalies in dogs. Among them, segmental aplasia of the caudal vena cava with cavo-azygos shunt stands out. Usually, dogs with this abnormality show no clinical signs, unlike the patient reported in this study. An eight-month-old male Border Collie was examined with clinical signs of motor incoordination and exercise intolerance. After ruling out cardiac anomalies by echocardiographic examination and detecting an abdominal vascular abnormality, CT angiography was used as a further diagnostic approach. The objective of this case report is to present the sonographic and angiotomographic aspects of a young dog with segmental aplasia of the caudal vena cava associated with cavo-azygos shunt, resulting in aneurysms with clinical signs of incoordination and exercise intolerance.
