摘　　要：目的探讨复杂性回收钩贴壁下腔静脉滤器的取出技巧及应用策略。方法收集因滤器回收钩贴壁、采用Günther Celect配套回收装置无法成功取出Celect下腔静脉滤器9例,采用交换导丝成襻法行下腔静脉滤器取出术。结果 9例患者,最长植入时间为142天,最短37天,平均(88.67±33.85)天。使用交换导丝成襻法8枚滤器成功取出,1例患者因下腔静脉严重弯曲致回收失败,滤器回收成功率为88.89%(8/9)。滤器回收耗时57~162min,平均(69.89±12.12)min。所有滤器取出后形态完整,术后下腔静脉造影复查未见管壁穿孔,对比剂外渗。结论采用交换导丝成襻法可有效提高回收钩贴壁下腔静脉滤器成功回收率,具有一定的临床应用价值。Objective To explore the techniques and strategies for the retrieval of the retractable inferior vena cava filter （IVCF）. Methods Celect IVCF retrieval was not removed successfully with Günther Celect recovery device in 9 cases and exchange-wire-loop removal of inferior vena cava filter method were applicated. Results The longest implanted time of 9 patients was 142 days, the shortest implanted time was 37 days, and the average time was （88.67±33.85）days. Eight filters were successfully removed and one failed due to severe bending of inferior vena cava. Filter retrieval rate was 88.89% （8/9）. The average retrieval time was （69.89±12.12）min （57-162 min）. No perforation of the wall and contrast agent were found in all patients after the inferior vena cava angiography. Conclusion For the retrieval of the hook heavily attached to the IVCF, the retrieval technique of using the exchange wire into the loop method can effectively improve the retrieval rate and has a certain clinical value.
