I82: Other venous embolism and thrombosis

I82.2: Embolism and thrombosis of vena cava

The vena cava collects the blood from the body. The vena cava goes straight into the heart. You have blood clots in your vena cava. This can cause the vena cava to narrow or get blocked. If the vena cava is blocked, the blood is no longer able to flow properly from the body to the heart. The blood can then get blocked as a result. The legs may then swell up, for example.

There are various reasons for blood clots forming. If someone has to lie down for a long time, or if the vascular wall has been injured, a blood clot can form more quickly. Some people are prone to blood clots. This is then congenital or caused by another disorder.

Some blood clots are formed elsewhere in the body. The blood clot may form in the legs, for example. The blood clot can then be swept away with the blood and it can get stuck somewhere in the vena cava.
