下腔静脉滤器预防肺栓塞及其并发症

目的 探讨下腔静脉滤器置入术(IVCF)预防肺动脉栓塞(PE)的疗效、相关并发症及处理.方法70例下肢深静脉血栓患者,溶(取)栓术前均行下腔静脉滤器置入术:永久性Trap Ease滤器(TEF)20枚,永久性Vena Tech滤器(VTF)31枚,可回收性OptEase~(TM)滤器(OEF)13枚,临时性TempoⅡ滤器8枚;71枚位置在肾静脉开口下方,1枚位置在肾静脉开口上方.结果 术后随访8～72个月.70例中,无一例出现PE,6例出现相关的并发症.结论 下腔静脉滤器置入可以有效预防肺梗死,但应严格掌握适应证.

Inferior vena cava filter placement for the prevention of pulmonary embolism and the complications related to the filter placement

Objective To investigate the effects of inferior vena cava (IVC) filter placement for the prevention of fatal pulmonary embolism and to discuss the management of complications related to the filter placement. Methods Seventy patients with proved deep vein thrombosis of lower extremity underwent inferior vena cava filter placement. A total of 72 IVC filters were implanted, which included 20 Trap Ease filters, 31Vena Tech filters, 13 retrievable OptEase~(TM) filters and 8 Tempo Ⅱ filters. One filter was deployed above the orifice of renal vein and the remaining 71 were deployed below the orifice of renal vein. Results All the patients were followed up for 8-72 months after the procedure. During the follow-up period no fatal pulmonary embolism occurred except that some complications related to the filter placement occurred in 6 cases.Conclusion Inferior vena cava filter placement can effectively prevent the occurrence of pulmonary embolism. Of course, this treatment should be strictly applied according to the indications.
