I82: Other venous embolism and thrombosis

I82.3: Embolism and thrombosis of renal vein

There are normally 2 kidneys in the body. They filter blood and create urine. They thus help to detoxify the body. Furthermore, the kidneys regulate the blood pressure and salt content in the blood, among other things. The renal vein collects the blood from the kidney. The blood is then carried to the heart.

You have blood clots in your renal vein. This can cause the renal vein to narrow or get blocked. If the renal vein is blocked, the blood is no longer able to flow properly from the kidney to the heart. This can damage the kidney.

Various kidney disorders can favor blood clotting in the renal veins.

Some blood clots are formed elsewhere in the body. The blood clot can then be swept away with the blood and it can get stuck in the renal vein.
