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 superior vena cava returns blood from the upper body to the heart, and the inferior vena cava returns the blood from the lower part of the body. The superior vena cava is thin-walled, and the blood is under low pressure. It lies near lymph nodes in the chest. Therefore, when the lymph nodes or the aorta of the heart get bigger, the superior vena cava is squeezed, blood flow slows, and complete blockage may occur.
