Inferior vena cava filters are increasingly utilized to prevent pulmonary emboli origi nating from lower extremity, pelvis, or caval thromboses. Unique indications exist for filter placement in the suprarenal portion of the vena cava. The largest reported experi ence in suprarenal position has involved the use of the Greenfield filter. Although unique in design, little differences have been described between the stainless steel and titanium version of this device. The authors present a case report of incomplete caval protection after successful placement of a stainless steel Greenfield filter in the suprarenal cava. Subtle differences between the titanium and the stainless steel Greenfield filter may exist and should be taken into consideration for placement in the suprarenal cava. Physiologic conditions supporting this premise are described. Further investigation between the two filter types appears justified.
