H. CAPAK: Three-dimensional multislice helical computed tomography in the diagnostics of vena azygos connection to the caudal vena cava in a dog -a case report. Vet. arhiv 87, 631-639, 2017. ABSTRACT In a four-year old Australian Cattle Dog bitch, CT angiography of the communication of the azygos vein with the interrupted caudal vena cava, without portocaval shunting is described. The communication of the azygos vein with the discontinued caudal vena cava is usually an incidental finding which

CT angiography and 3D multiplanar reconstruction (MIP and VR) enable us to distinguish the processes regarding the direction and size of anomalies of the blood vessels. By means of imaging in two basic projections using the velocity ratio (VR) a significant enlargement and the communication of the caudal vena cava with a significantly enlarged azygos vein and its connection with the cranial vena cava is shown.
