The inferior vena cava IVC is the largest vein in the body, draining blood from the abdomen, pelvis and lower extremities. This pictorial review summarises normal anatomy and embryological development of the IVC.

Cava inferior

The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins , usually at the level of the fifth lumbar vertebra. The inferior vena cava is the lower " inferior " of the two venae cavae , the two large veins that carry deoxygenated blood from the body to the right atrium of the heart: 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. Together, the venae cavae in addition to the coronary sinus , which carries blood from the muscle of the heart itself form the venous counterparts of the aorta. It is a large retroperitoneal vein that lies posterior to the abdominal cavity and runs along the right side of the vertebral column. The name derives from Latin : vena, "vein", cavus, "hollow". The IVC is formed by the joining of the left and right common iliac veins and brings collected blood into the right atrium of the heart. The inferior vena cava begins as the left and right common iliac veins behind the abdomen unite, at about the level of L5. Because 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. In the embryo , the inferior vena cava and right auricle are separated by the valve of the inferior vena cava , also known as the Eustachian valve. In the adult, this valve typically has totally regressed or remains as a small fold of endocardium. Rarely, the inferior vena cava may vary in its size and position.

The inferior vena cava IVC plural: inferior venae cavae is one of the great vessels that drains venous blood from the lower limbs , pelvis and abdomen into the right atrium of the heart. The inferior vena cava is formed by the confluence of the two common iliac veins at the L5 vertebral level. The IVC has a retroperitoneal course within the abdominal cavity. It runs along the right side of the vertebral column with the aorta lying laterally on the left. Various other veins drain into the IVC along its course before it passes through the diaphragm at the caval hiatus at the T8 level. Its intrathoracic course is very short before draining into the right atrium at the inferior cavoatrial junction. T8: paired inferior phrenic veins.

Cava inferior

Responsible for carrying lower body blood back to the heart. The inferior vena cava also known as IVC or the posterior vena cava is a large vein that carries blood from the torso and lower body to the right side of the heart. From there the blood is pumped to the lungs to get oxygen before going to the left side of the heart to be pumped back out to the body. The IVC gets its name from its structure and location.
