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.

Unpaired median sacral vein. Although some practices continue to use the Robson staging system for RCC, it has largely been replaced by the tumour—node—metastasis TNM cava inferior system of malignant tumours.

Insights into Imaging volume 12 , Article number: Cite this article. Metrics details. 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. In addition, we highlight a wide range of anatomical variants, acquired pathologies and a common pitfall in imaging of the IVC. This information is essential for clinical decision making and to reduce misdiagnosis. Recurrent pulmonary embolism following routine infrarenal IVC filter placement should raise suspicion of a duplicated IVC. Tumour thrombus is differentiated from bland thrombus by filling defect enhancement, vessel lumen expansion and contiguity with the mass.

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 inferior vena cava is also referred to as the posterior vena cava. Deoxygenated blood means most of the oxygen has been removed by tissues, and therefore the blood is darker. The inferior vena cava empties into the right atrium of the heart.
