Inferior vena cava Inferior vena cava. The inferior vena cava is also referred to as the posterior vena cava. The inferior vena cava is a large vein that carries de-oxygenated blood from the lower body to the heart. De-oxygenated blood means most of the oxygen has been removed by tissues, and therefore the blood is darker.he right atrium is located on the lower right back side of the heart. The inferior vena cava runs posterior, or behind, the abdominal cavity. This vein also runs alongside the right vertebral column of the spine. The inferior vena cava is the result of two major leg veins coming together.

Superior Vena Cava Syndrome Superior Vena Cava Syndrome. The superior vena cava is a major vein in a person’s body. It carries blood from the head, neck, upper chest, and arms to the heart. Superior vena cava syndrome (SVCS) occurs when a person’s superior vena cava is partially blocked or compressed. Cancer is usually the main cause of SVCS.

Superior vena cava The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart. It is a large-diameter (24 mm), yet short, vein that receives venous return from the upper half of the body, above the diaphragm. (Venous return from the lower half, below the diaphragm, flows through the inferior vena cava.) The SVC is located in the anterior right superior mediastinum. It is the typical site of central venous access (CVA) via a central venous catheter or a peripherally inserted central catheter.

The inferior vena cava (or caudal vena cava in some animals) travels up alongside the abdominal aorta with blood from the lower part of the body (see # 11 in the diagram).

Superior Vena Cava Syndrome Introduction. The superior vena cava is a large vein located in the upper chest, which collects blood from the head and arms and delivers it back to the right atrium of the heart. If this vein is compressed by outside structures, or if a thrombus or clot develops within it, return blood flow to the heart is impeded.
