Renal vein thrombosis

Definition:

Renal vein thrombosis is a blood clot that develops in the vein that drains blood from the kidney.


Alternative Names:
Clot in the renal vein; Occlusion - renal vein
Causes, incidence, and risk factors:

Renal vein thrombosis is a fairly uncommon situation that may happen after trauma to the abdomen or back, or it may occur because of a tumor, stricture (scar formation), or other blockage of the vein. It may be associated with nephrotic syndrome.

In some children it occurs after severe dehydration, and is a more serious condition than in adults. Dehydration is the most common cause of renal vein thrombosis in infants.
