Twelve patients have had Greenfield vena cava filter placement above the renal veins since 1975. The indication for placement was most commonly contraindication to anticoagulation or recurrent pulmonary embolism during treatment. The follow-up consisted of physical examination, isotope phlebography-lung scan, venous Doppler evaluation, serum specimen evaluation of renal function, and abdominal roentgenograms. The follow-up averaged 16.9 +/- 6.2 months (range 5 weeks to 58 months) in 10 patients. Five patients died after filter insertion, but no death was attributable to filter placement or recurrent embolism. Renal function was unchanged in all patients. Recurrent embolism was documented postoperatively in one patient. Migration of the filter was not observed. The vena cava was demonstrated to be patent in all patients. Two patients had evidence of embolus trapped in the filter.
自1975年以来，有12例患者在肾静脉上方放置了格林菲尔德腔静脉滤器。放置滤器的指征最常见的是抗凝治疗的禁忌症或治疗期间的复发性肺栓塞。随访包括体格检查、同位素静脉造影-肺部扫描、静脉多普勒评估、肾功能血清标本评估以及腹部X线片。10例患者的随访平均为16.9±6.2个月（范围5周-58个月）。5例患者在滤器置入后死亡，但无一例死亡归因于滤器置入或复发性栓塞。所有患者的肾功能均无变化。术后有1例患者记录到复发性栓塞。未观察到滤器移位。所有患者的腔静脉均显示通畅。2例患者有栓子被困在滤器中的证据。
