  2. Inferior vena cava - Wikipedia

    en.wikipedia.org/wiki/Inferior_vena_cava

    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 .

  3. Agenesis of the vena cava - Wikipedia

    en.wikipedia.org/wiki/Agenesis_of_the_vena_cava

    Agenesis of the vena cava is a genetic defect of the inferior vena cava. It comes about when, during development of the foetus, the right subcardinal vein does not connect as it should to the hepatic sinusoids. [1] [2]: 628 . Agenesis of the superior vena cava may also occur; it is very rare. [3]

  4. Crista dividens - Wikipedia

    en.wikipedia.org/wiki/Crista_dividens

    The crista dividens plays a role in separating oxygenated blood from the ductus venosus and deoxygenated blood from the inferior vena cava (IVC) draining the caudal portion of the fetus into the left and right atria, respectively. [1] The crista dividens is located on the inferior edge of the interatrial septum and faces

  5. Venae cavae - Wikipedia

    en.wikipedia.org/wiki/Venae_cavae

    In anatomy, the venae cavae (/ ˈ v iː n i ˈ k eɪ v i /; [1] sg.: vena cava / ˈ v iː n ə ˈ k eɪ v ə /; from Latin 'hollow veins') [2] are two large veins (great vessels) that return deoxygenated blood from the body into the heart. In humans they are the superior vena cava and the inferior vena cava, and both empty into the right atrium ...

  6. Inferior vena cava syndrome - Wikipedia

    en.wikipedia.org/wiki/Inferior_vena_cava_syndrome

    Inferior vena cava syndrome (IVCS) is a very rare constellation of symptoms resulting from either obstruction or stenosis of the inferior vena cava. It can be caused by physical invasion or compression by a pathological process, or by thrombosis within the vein itself. It can also occur during pregnancy. Symptoms including high venous pressure ...

  7. Scimitar syndrome - Wikipedia

    en.wikipedia.org/wiki/Scimitar_syndrome

    The syndrome associated with PAPVR is more commonly known as Scimitar syndrome after the curvilinear pattern created on a chest radiograph by the pulmonary veins that drain to the inferior vena cava. [2] This radiographic density often has the shape of a scimitar, a type of curved sword. [2] The syndrome was first described by Catherine Neill ...

  8. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    Oxygen-deprived blood from the superior and inferior vena cava enters the right atrium of the heart and flows through the tricuspid valve (right atrioventricular valve) into the right ventricle, from which it is then pumped through the pulmonary semilunar valve into the pulmonary artery to the lungs.

  9. Congenital stenosis of vena cava - Wikipedia

    en.wikipedia.org/wiki/Congenital_stenosis_of...

    Congenital stenosis of vena cava is a congenital anomaly in which the superior vena cava or inferior vena cava has an aberrant interruption or coarctation. In some cases, it can be asymptomatic, [ 1 ] and in other cases it can lead to fluid accumulation and cardiopulmonary collapse.
