Objebtive To explore the techniques and related complications of removing retrievable inferior vena cava filter. Methods From May 2008 to March 2015, seventy-two patients with lower limb deep vein thrombosis formation clearly diagnosed by color Doppler ultrasound were imbedded retrievable filter. The inferior vena cava filter was removed from thirty-five cases who had successful thrombolysis and no risk of pulmonary vein thrombosis. Results The inferior vena cava filter was successfully removed in thirty-three of thirty-five (94%) cases. Among the thirty-three cases, three cases revealed capture thrombus inside filter after removal, two cases revealed interior vena cava perforation during removal process and on postoperative angiography, and one case suffered from intractable arrhythmia without pulmonary embolism and sudden death after positive symptomatic treatment. The remain two cases of failed removal turned into permanent indwelling. Conclusion Normative and skilled removal of inferior vena cava filter can avoid long-term complications of chronically indwelling of inferior vena cava filter, and can reduce the occurrence of complications of removing inferior vena cava.%目的 探讨可回收下腔静脉滤器取出技巧及出现的相关并发症.方法 收集2008年5月-2015年3月接受彩超检查发现下肢深静脉血栓形成并置入可回收滤器的72例病人,对其中的35例溶栓效果良好且无发生肺栓塞风险的病人行下腔静脉滤器取出术.结果 35例病人中下腔静脉滤器成功取出33例,取出率94%,其中有3例病人取出滤器后发现滤器内捕获血栓,2例滤器取出过程中及术后造影发现下腔静脉穿孔,1例发生顽固性心律失常,经积极对症处理后未发现症状性肺栓塞及猝死等严重情况.另外2例取出失败后转为永久留置.结论 规范、熟练地操作下腔静脉滤器取出术既可以避免下腔静脉滤器长期留置的远期并发症,同时也减少下腔静脉滤器取出术操作中并发症的发生.
