下肢静脉血栓形成后下腔静脉滤网置入预防肺栓塞14例报告

目的探讨数字减影血管造影（digital subtraction angiography，DSA）引导下置入腔静脉滤网对深静脉血栓形成后肺栓塞（pulmonary embolism，PE）的预防作用。方法2003年10月-2004年12月，我院对14例下肢深静脉血栓形成在DSA引导下行下腔静脉滤网置入术，其中12例在滤器置入术后立即行下肢深静脉取栓术，2例保守治疗。结果14例手术均获得成功，手术时问85～115min，平均95min。无并发症。随访1-14个月，平均6个月，均无PE发生。术前曾出现PE的5例滤器置入后未再发生PE。结论下腔静脉滤网置入是一种简便、安全措施，可有效预防深静脉血栓形成后PE的发生。

Inferior vena cava filter placement for the prevention of pulmonary embolism after deep vein thrombosis of lower extremities:Report of 14 cases

Objective To evaluate the efficacy of inferior vena cava filter placement guided by digital subtraction angiography(DSA) for the prevention of pulmonary embolism(PE) after deep vein thrombosis(DVT) of the lower extremities.Methods Under the guidance of DSA,inferior vena cava filter placement was performed in 14 cases of deep vein thrombosis of the lower extremities from October 2003 to December 2004.Of the 14 cases,12 cases were given a simultaneous thrombectomy and 2 cases were treated conservatively.Results Filters were successfully placed in all the cases.The operation time was 85~115 min(mean,95 min).No complications were found during a follow-up of 1~14 months(mean,6 months).No recurrence of pulmonary embolism was seen included 5 patients who had survived previous pulmonary embolism attacks before the placement.Conclusions Inferior vena cava filter placement is a simple,safe,and effective method in the prevention of pulmonary embolism after deep vein thrombosis of the lower extremities.
