Key result
Inferior vena cava filters effectively prevented pulmonary thromboembolism with 0% recurrence during a mean 27-month follow-up, though permanent filters showed a tendency to penetrate the IVC wall.
Why the study?
Does inferior vena cava filter placement prevent pulmonary thromboembolism and what are the long-term complications in patients with deep vein thrombosis?
Observational (n=74)
No
Does inferior vena cava filter placement prevent pulmonary thromboembolism and what are the long-term complications in patients with deep vein thrombosis?
Inferior vena cava filters effectively prevent pulmonary thromboembolism, but permanent deployment requires careful long-term observation due to a high rate of asymptomatic IVC wall penetration.
May support IVC filter use for PE prevention in DVT; leaves open long-term safety of permanent devices due to wall penetration.
要約:下大静脈フィルター(inferior vena cava filter; IVCF)は,深部静脈血栓症による致死的な肺血栓塞栓症(pulmonary thromboembolism; PTE)を予防するため留置されるが,その適応については慎重に考慮する必要がある.IVCF の有用性について明らかにするため,当院におけるIVCF 留置例を後ろ向きに調査した.症例は2001 年1 月から2012年12 月までに当院でIVCF 留置した連続74 例を対象(永久留置46 例,非永久留置28 例)とし,平均観察期間は48 カ月であった.2004 年から回収可能型であるGünther Tulip filter(GTF)を一時用,永久留置用として使用した.GTF の回収成功率86.7%(13/15),回収率は25.5%(13/51)であった.IVCF留置例において抗凝固療法は93.5%に継続されており明らかなPTE の再発はみられなかった.フィルター留置に関連した死亡例はなく,2 症例に抗凝固療法に伴う出血を認めた.IVCF 永久留置例の5 例に無症候性IVC 穿孔を認めた.フィルターの永久留置例において抗凝固療法の継続,定期的なIVCF の評価が必要であると考えられた.

Nakaema et al. (2014) conducted an observational in Pulmonary thromboembolism and deep vein thrombosis (n=74). Inferior vena cava filter (IVCF) was evaluated on Recurrence or occurrence of pulmonary thromboembolism (PTE). Inferior vena cava filters effectively prevented pulmonary thromboembolism with 0% recurrence during a mean 27-month follow-up, though permanent filters showed a tendency to penetrate the IVC wall.
