Acute Renal Vein Thrombosis: A Case Report of Successful Treatment with Mechanical Thromboaspiration.

Treatment of renal vein thromboses has previously been limited to conventional anticoagulation. We describe a case of successful treatment of acute native renal vein thrombosis (RVT) in a 61-year-old fit-and-well female using mechanical thromboaspiration without the use of thrombolysis. The report demonstrates the computed tomographic appearances of an acute RVT, the venographic images taken before and after thromboaspiration, and the magnetic resonance imaging of the kidney performed 3 months later, showing complete resolution of the thrombus and normal appearances of the kidney. We believe this case to be the first published case of a safe and successful treatment of acute native RVT using the Penumbra Indigo® mechanical aspiration system, highlighting the importance of access to skilled interventional radiologists for treatment of this rare condition.
