The inferior vena cava (or IVC) (Latin: vena, vein, cavus, hollow), is one of the venae cavae, two large veins, that carries deoxygenated blood from the body into the right atrium of the heart.n the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly. On the left, they drain into the renal vein which in turn drains into the inferior vena cava. By contrast, all the lumbar veins and hepatic veins usually drain directly into the inferior vena cava.
