Suprarenal inferior vena cava filter placement prior to transcatheter arterial embolization (TAE) of a renal cell carcinoma with large renal vein tumor thrombus: prevention of pulmonary tumor emboli after TAE.

To prevent embolization of necrotic renal vein tumor after transcatheter embolization of a left renal cell carcinoma, we placed a suprarenal Bird's nest inferior vena cava filter. The patient tolerated the procedure well and had extensive tumor infarction including the tumor thrombus on 6-month follow-up computed tomography.
