Abstract

Absence of caudal/inferior vena cava (CVC/IVC) with azygos/hemiazygos continuation is an uncommon vascular anomaly. To the best of the investigators knowledge, this is the first report of absence of CVC/IVC with azygos/hemiazygos continuation in the swine in the world. In this case, absence of CVC/IVC was confirmed by venography and necropsy. The recognition of this congenital venous anomaly (CVC/IVC interruption with azygos/hemiazygos continuation) is important for interventional radiologist and cardiologist.

Key Words: Caudal vena cava, Inferior vena cava, azygos/hemiazygos vein, congenital anomaly
