Overview, Causes, & 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.

Renal vein thrombosis should be suspected if symptoms develop after femoral vein cannulation (such as for an angiogram test).
