Renal vein thrombosis

  • Alternative Names

    Clot in the renal vein; Occlusion - renal vein


    The treatment is focused on preventing new clot formations and reducing the risk of the clot traveling to other locations in the body (embolization).

    You may get medications that prevent blood clotting (anticoagulants) to stop new clots from forming. Your doctor may recommend bedrest or limited activity for a brief period.

    If severe acute renal failure develops, you may need dialysis, but it should be temporary.

    Expectations (prognosis)

    Renal vein thrombosis usually gets better over time without permanently injuring the kidneys.

    • Acute renal failure (especially if thrombosis occurs in a dehydrated child)
    • Blood clot moves to the lungs (pulmonary embolism)
    • Formation of new blood clots
