The bird's nest inferior vena cava filter, in clinical trial since 1982, has been placed in 568 patients at risk for pulmonary embolism. Of the 481 patients in whom the filter had been in place for 6 months or more, 440 were followed up clinically. The prevalence of clinically suspected recurrent pulmonary thromboembolism was 2.7% (12 patients) and that of inferior vena cava filter occlusion was 2.9% (13 patients). With the initial filter design, filter migration occurred in five patients. No migrations have occurred in the 147 patients treated with the filter after its modification to improve the anchoring system for greater stability. The bird's nest filter has proved safe and effective in the prevention of pulmonary embolism.
自1982年起进行临床试验的鸟巢式下腔静脉滤器，已应用于568例有肺栓塞风险的患者。在481例滤器植入时间达6个月或更长时间的患者中，440例接受了临床随访。临床疑似复发性肺血栓栓塞的发生率为2.7%（12例患者），下腔静脉滤器闭塞的发生率为2.9%（13例患者）。采用最初的滤器设计时，有5例患者发生滤器移位。在对滤器进行改进以增强锚固系统稳定性后，接受该滤器治疗的147例患者中未再发生移位。鸟巢式滤器已证明在预防肺栓塞方面安全有效。
