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 ...
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.
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.
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 .
[5] [20] [21] DVT can also exist without causing any symptoms. [22] Signs and symptoms help in determining the likelihood of DVT, but they are not used alone for diagnosis. [19] At times, DVT can cause symptoms in both arms or both legs, as with bilateral DVT. [25] Rarely, a clot in the inferior vena cava can cause both legs to swell. [26]
If the impaired vein function causes significant symptoms, such as swelling and ulcer formation, it is referred to as chronic venous disease. [3] It is sometimes called chronic peripheral venous insufficiency and should not be confused with post-thrombotic syndrome in which the deep veins have been damaged by previous deep vein thrombosis .
According to this theory, dural holes and intracranial hypotension are symptoms caused by low venous pressure in the epidural space. When leg muscles pump blood towards the heart, and pressure in the inferior vena cava vein becomes negative, the network of epidural veins is overdrained, causing CSF to be aspirated into the epidural space. True ...
Budd-Chiari syndrome is the blockage of a hepatic vein or of the hepatic part of the inferior vena cava. This form of thrombosis presents with abdominal pain, ascites and enlarged liver. Treatment varies between therapy and surgical intervention by the use of shunts. [5]
