The superior vena cava (also known as the cava or cva) is a large diameter (24 mm), yet short, vein that carries deoxygenated blood from the upper half of the body to the heart 's right atrium. It is located in the anterior right superior mediastinum.
The inferior vena cava carries blood from the lower half of the body whilst the superior vena cava carries blood from the upper half of the body. It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.ecause the inferior vena cava is located to the right of the midline, drainage of the tributaries is not always symmetrical. On 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.
