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 ...
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. [1] On the left, they drain into the renal vein which in turn drains into the inferior vena cava. [1]
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.
[3] [25] Measurement of the vena cava during the breathing cycle can help assess volume status. [22] [24] A point-of-care echocardiogram can also assess for causes of obstructive shock. The vena cava would be dilated due to the obstruction. In pulmonary embolism, the right ventricle will be dilated.
Inferior vena cava filter Used inferior vena cava filter There are two situations when an inferior vena cava filter is considered advantageous, and those are if anticoagulant therapy is contraindicated (e.g. shortly after a major operation), or a person has a pulmonary embolus despite being anticoagulated.

An atriocaval shunt (ACS) is an intraoperative surgical shunt between the atrium of the heart and the inferior vena cava. It is used during the repair of larger juxtahepatic (next to the liver) vascular injuries such as an injury to the local vena cava. Injuries to the inferior vena cava are challenging, those behind the liver being the most ...
structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein; structures of the respiratory system, including the diaphragm, trachea, bronchi and lungs [1]
There are case reports of the inferior vena cava being compressed by the iliac arteries or right-sided compression syndromes, but the vast majority are on the left side. While this is the suspected cause of the syndrome, the left iliac vein is frequently seen to be compressed in asymptomatic patients, and considered an anatomic variant.
