Abstract Purpose To determine the influence of filter leg-interlocking on filtering efficiency of titanium Greenfield inferior vena cava filters in anin vitro model. Methods Titanium Greenfield filters (TGF) were placed in an inferior vena cava (IVC) flow phantom with no interlocking legs, or with one or two pairs of legs interlocked. Clot emboli of varying sizes were introduced into the stream of flow, and the frequency of successful captures by the deformed filters was recorded. Results Interlocking filter legs diminished the filtering efficiency of the TGF by up to 80% with the flow phantom in a horizontal position; no such compromise existed when the phantom was in a vertical position. Conclusion When leg interlocking is verified radiographically, the filtering efficiency of the TGF is reduced, and placement of a second IVC filter may be indicated.
