PURPOSE: The purpose of this study was to determine the outcomes for @entity1 with @entity702 Greenfield vena caval filters (TGFs) and, in particular, to evaluate the effect of filter leg distribution on recurrent @entity1151 ( @entity1151 ) and @entity432 . METHODS: Physical examination, abdominal plain films, and duplex ultrasound examinations of the inferior vena cava and lower extremities were obtained annually and recorded in a Filter Database. RESULTS: Seven hundred eighty-three TGFs have been placed since 1989. Follow-up was available for 373 @entity1 , or 65% of the surviving @entity1 , over 1 to 84 months (mean, 33 months). Asymmetry was identified in 42 placements (5%), and 35 of these @entity1 had at least one follow-up examination. The overall incidence of recurrent @entity1151 was 3.2% (12 of 373), whereas the caval patency rate was 97.8% (265 of 271). These outcomes were not significantly different for @entity1 who had asymmetric filters (p = 0.1 and 0.18, respectively). CONCLUSIONS: Filter leg distribution does not appear to be associated with an increased incidence of recurrent @entity1151 or @entity432 . These data support earlier in vitro findings. The long-term results with the TGF are comparable with the results of the original stainless steel Greenfield filter.
