Vena cava filter (VCF) application is the method of choice to prevent recurrent pulmonary embolism in patients with deep venous thrombosis. Because of the reported complications after VCF placement we summarize our long-term follow-up results with the LGM and Titanium Greenfield (TG) devices.
Eighty-seven LGM VCF and 17 TG VCF were placed in 104 patients (average age 64 years). The follow-up examinations were performed by color-coded duplex sonography, plain radiographs, cavography, and computed tomography (CT). The maximum observation time was 81 months.
Filter migration occurred in 11% (8/76) of the LGM VCF and 15% (2/13) of the TG VCF. Vena cava thrombosis was seen in 17% (13/76) of the patients with an LGM VCF and in 31% (4/13) of those with a TG VCF. The patency rate was 95% (72/76) for the LGM VCF and 92% (12/13) for the TG VCF. Pulmonary embolism was noted in 3 patients after LGM VCF insertion and in no patient after TG VCF insertion.
A VCF should only be inserted in a patient after pulmonary embolism and when there is strict proof of the indication.
腔静脉滤器（VCF）应用是预防深静脉血栓形成患者复发性肺栓塞的首选方法。鉴于报道的VCF置入术后并发症，我们总结了使用LGM和钛制格林菲尔德（TG）装置的长期随访结果。
104例患者（平均年龄64岁）置入了87个LGM VCF和17个TG VCF。通过彩色编码双功超声、X线平片、腔静脉造影和计算机断层扫描（CT）进行随访检查。最长观察时间为81个月。
LGM VCF的移位率为11%（8/76），TG VCF的移位率为15%（2/13）。LGM VCF患者中17%（13/76）出现腔静脉血栓形成，TG VCF患者中31%（4/13）出现腔静脉血栓形成。LGM VCF的通畅率为95%（72/76），TG VCF的通畅率为92%（12/13）。LGM VCF置入术后3例患者发生肺栓塞，TG VCF置入术后无患者发生肺栓塞。
仅在发生肺栓塞且有严格指征证据的患者中才应置入VCF。
