下腔静脉滤器在下肢深静脉血栓治疗中的应用及意义

目的探讨下肢深静脉血栓形成（DVT）患者行下腔静脉滤器（IVCF）植入的手术指征、并发症、意义及术后抗凝、溶栓治疗的必要性。方法回顾性分析2008年1月～2009年3月我院31例下肢深静脉血栓患者行下腔静脉滤器植入的临床资料,并对之随防。结果所有患者均成功将滤器置于双侧肾静脉开口平面下方,术中无严重并发症发生,术后随访6～20个月,均无症状性肺栓塞（PE）发生,1例滤器内有血栓形成,发生率为3.2%。无其他相关并发症。结论下腔静脉滤器植入可有效预防致命性肺栓塞发生,严格的手术操作及术后正规的抗凝溶栓治疗是防止滤器植入术并发症的关键。

The application and significance of inferior vena cava filter placement for deep vein thrombosis of the lower extremity

Objective To assess the indications,complications,significance and the essentiality of anticoagulation and thrombolysis therapy post-operation of inferior vena cava filters（IVCF）placement in cases of deep vein thrombosis（DVT）of the lower extremity.Methods Retrospective analysis the clinic data of the 31 cases with DVT of the lower extremity who accepted IVCF placement from January 2008 to March 2009 in our hospital,and follow-up all of the cases.Results The filters were successfully inserted in subrenal vena cava without serious complications happening in the operation.there was no case of symptomatic pulmonary embolism（PE）occurred during 6～20 months of follow-up,there was one case of IVC thrombosis at the site of filter,which the incidence rate was 3.2%.There were no other complications.Conclusion IVCF placement can prevent fatal PE due to DVT effectively.Strict operative procedure and regular anticoagulation and thrombolysis therapy post-operation are the key of preventing the complications of filter placement.
