Evaluate the success rate of retrievable inferior vena cava filter (IVC) removal in a tertiary care practice.
Retrievable IVC filters became readily available in the United States following Food and Drug Administration approval in 2003, and their use has increased dramatically. They represent an attractive option for patients with contraindications to anticoagulation who may only need short-term protection against pulmonary embolism.
All patients who had undergone placement of a retrievable IVC filter at Mayo Clinic between 2003 and 2005 were retrospectively reviewed to evaluate our initial experience with retrievable inferior vena cava filters at a large tertiary care center.
During a three-year-period of time, Mayo Clinic, Rochester, MN placed 892 IVC filters of which 460 were retrievable. Of the 460 retrievable filters placed (249 Günther Tulip®, 207 Recovery®, and 4 OptEase®), retrieval was attempted in 223 (48.5%). Of 223 initial attempts, 196 (87.9%) were initially successful and 27 (12.1%) were unsuccessful. Of the 27 unsuccessful initial retrieval attempts, 23 (85.2%) were because of the presence of significant thrombus within the filter and 4 (14.8%) were because of tilting and strut perforation. Of the 23 filters containing significant thrombus, 9 (39.1%) were later retrieved after a period of anticoagulation and resolution of the thrombus.
Retrievable IVC filters can be removed with a high degree of success. Approximately one in ten retrievable IVC filter removal attempts may fail initially, usually because of significant thrombus within the filter. This does not preclude possible removal at a later date.
评估在三级医疗实践中可回收下腔静脉滤器（IVC）取出的成功率。
2003年美国食品药品监督管理局批准后，可回收IVC滤器在美国 readily available ，其使用量急剧增加。对于抗凝治疗有禁忌且可能仅需短期预防肺栓塞的患者而言，它们是一个有吸引力的选择。
对2003年至200年期间在梅奥诊所接受可回收IVC滤器植入的所有患者进行回顾性研究，以评估我们在大型三级医疗中心使用可回收下腔静脉滤器的初步经验。
在三年期间，明尼苏达州罗切斯特市的梅奥诊所植入了892个IVC滤器，其中460个是可回收的。在植入的460个可回收滤器中（249个Günther Tulip®，207个Recovery®，4个OptEase®），223个（48.5%）尝试进行取出。在223次初次尝试中，196次（87.9%）初次成功，27次（12.1%）未成功。在27次初次取出失败的尝试中，23次（85.2%）是因为滤器内存在大量血栓，4次（14.8%）是因为倾斜和支柱穿孔。在23个含有大量血栓的滤器中，9个（39.1%）在经过一段时间的抗凝和血栓溶解后后来被取出。
可回收IVC滤器可以高成功率取出。大约十分之一的可回收IVC滤器取出尝试最初可能失败，通常是因为滤器内存在大量血栓。但这并不排除日后取出的可能性。
