本研究的目的是表征不锈钢格林菲尔德过滤器的长期安全性和有效性。在资深作者（L.J.G.）任职期间在三家机构接受格林菲尔德滤器置入术的所有患者前瞻性地进入滤器登记研究，并每年进行随访。随访包括评价静脉疾病或肺栓塞复发状态的临床检查、确定滤器稳定性的腹部X线片以及下腔静脉和下肢通畅性评价。本报告总结了20年的经验。肺栓塞复发率为4%，腔静脉通畅率为96%。在8%的病例中观察到一些无临床意义的滤器移动。无手术死亡，发病率极低。格林菲尔德滤器插入可长期防止肺栓塞，同时保持腔静脉通畅。
The purpose of this study was to characterize the long-term safety and efficacy of the stainless-steel Greenfield filter. All patients who underwent Greenfield filter placement at three institutions during tenure of the senior author (L.J.G.) were entered prospectively into a filter registry and followed on an annual basis. Follow-up consisted of clinical examination to evaluate the status of venous disease or recurrence of pulmonary embolism, abdominal radiographs to determine the stability of the filter and an evaluation of the patency of the inferior vena cava and lower extremities. This report summarizes the 20-year experience. The rate of recurrent pulmonary embolism was 4% and the caval patency rate was 96%. Some filter movement of no clinical significance was seen in 8% of cases. There was no procedural mortality and morbidity was minimal. Greenfield filter insertion provides long-term protection from pulmonary embolism while preserving caval patency.
