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 ...
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 .

Increased pressure in the sublobular branches of the hepatic veins causes an engorgement of venous blood, and is most frequently due to chronic cardiac lesions, especially those affecting the right heart (e.g., right-sided heart failure), the blood being dammed back in the inferior vena cava and hepatic veins.
Produces abdominal collateral veins to bypass the blocked inferior vena cava and permit venous return from the legs. Determine the direction of flow in the veins below the umbilicus. After pushing down on the prominent vein, blood will: flow toward the legs → caput medusae; flow toward the head → inferior vena cava obstruction.
The right hepatic vein is the longest and largest of all the hepatic veins. It drains the liver segments VI and VII in their entirety, and variably participates in the drainage of segments V and VIII; the extent of drainage of the latter two segments by the right hepatic veins as opposed to the middle hepatic vein and possible variant accessory veins determines the calibre of the right hepatic ...
Dilated coronary sinus is also seen in some congenital cardiovascular conditions, such as persistent left superior vena cava, [8] and total anomalous pulmonary venous return. [9] In Cardiac Resynchronization Therapy (CRT) procedures, a critical step involves the insertion of a pacing lead into the coronary vein system. However, the anatomical ...
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. It is the largest vein in the human body. It is the largest vein in the human body.
