What is the lower vena cava?

Lower Vena Cava is a large heart vein that brings deoxygenated blood from parts of the lower body, including legs, abdomen and pelvis, to the heart to be oxygenated. From the heart, this blood is then pumped back by the body to supply oxygen into the body cells. This large vein is also known as the rear vena cava, flows into the right heart of the heart and connects on the underside of the back of the hall. Its additional vein, the superior vena cava, which supplies blood from the upper body, also flows into the right atrium, but does so through the upper part of the chamber. These smaller veins serve specific areas of the lower body and then connect when blood continues its way back by the heart. On the other hand, the iliakal vein and other tributaries are fed even smaller veins and still smaller veins feed these veins and ensure that deoxygenated blood from each cell of the body is spread back by the heart.

Some problems that may develop in the lower venaCava, include compression and thrombosis. Compression is a more common problem with this vein and can occur due to different factors. In some cases, the vein is compressed by the aortic and more often growing uterus during pregnancy. For this reason, pregnant women are recommended to sleep on the left side to reduce the possibility of compressing this large vein, which can lead to dizziness and fainting. For the same reasons, pregnant women should be unconscious to the left sides while waiting for treatment.

The

thrombosis of the lower vena Cava is relatively rare and occurs due to various clotting disorders that cause deep venous thrombosis or lead to a higher risk of blood clots in the veins. Possible treatment of thrombosis is the location of the filter that breaks the evolving clots in the vein. Unfortunately, the filter can sometimes cause an obstacle in the vein, leading to other complications. Other causes of obstruction, in addition to compression, include tumors such as kidney cancer. Blocking or other obstacles are also referred to as JAKO subordinate vena Cava syndrome.
