可回收下腔静脉滤器回收技巧和策略探讨

目的探讨疑难性可回收下腔静脉滤器的回收技巧和策略。方法 2010年1月—2013年6月收治采用常规圈套技术无法成功取出的下腔静脉滤器置入术后患者30例,采用导丝成袢法、胃镜活检钳辅助法及猪尾导管搅拌法行下腔静脉滤器取出术。结果成功回收下腔静脉滤器30例(100%)。导丝成袢法取出8例,胃镜活检钳辅助法取出12例,猪尾导管搅拌法取出10例。回收过程用时20⁹0 min,中位时间50.5 min。滤器在体内留置时间为1490 min,中位时间50.5 min。滤器在体内留置时间为14⁶0 d,中位数25.6 d。术后3 d内全部患者顺利出院。结论对于疑难性可回收下腔静脉滤器采用多种辅助性圈套技术可有效提高其回收率,有一定的临床应用价值。

Exploration on tips and strategies of retrievals for refractory inferior vena cava filter

Objective To explore the difficult nature of the inferior vena cava filter recyclable recycling techniques and strategies.Methods From January 2010 to June 2013, 30 patients who admitted to hospital and using conventional tech -niques cannot be successfully removed the snare inferior vena cava filter implantation by using a guide wire into a loop method , endoscopy biopsy forceps assisted and the pigtail catheter mixing method inferior vena cava filter removal surgery .Results Successfully recovered inferior vena cava filter in 30 cases （100%）.Remove the guide wire into a loop of 8 cases, endoscopy biopsy forceps-assisted method to remove in 12 cases, mixing method pigtail catheter removed in 10 cases.Recovery process takes 20 -90 min, the median time 50.5 min.Filters in vivo retention time of 14 -60 d, median 25.6 d.All patients were successfully discharged within 3 d.Conclusion For the difficult nature of recyclable inferior vena cava filter trap using a varie ty of assistive technology can effectively improve their recovery ,there are some clinical value.
