Abstract
The CT angiographic features of azygous continuation of an interrupted caudal vena cava in dogs with and without portocaval shunting are described. Azygous continuation of a discontinuous caudal vena cava is usually an incidental finding, not associated with portosystemic shunting. Identification of an associated portosystemic shunt will determine the need for surgical intervention. CT angiography provides a means for making this distinction and details the course and size of the anomalous vessels. Focal widening of the caudal vena cava on a VD thoracic radiograph should raise suspicion for azygous vein distension.
