A large vein that carries blood to the heart from other areas of the body. The most common cause is portal hypertension. In adults, an IVC collapsibility index of greater than 50% is associated with reduced right atrial pressure and severe dehydration, and indicates that the patient needs fluid therapy(23). The vitelline vein contributes to the hepatic segment of the IVC. They deliver deoxygenated blood from the liver and other lower digestive organs like the colon, small intestine, stomach, and pancreas, back to the heart; this is done via the IVC. Since the liver serves the important function of filtering blood as it moves from the digestive tract, these veins are particularly important for overall health.
