The aim of this study was to evaluate our experience with the retrievable Cook Celect inferior vena cava (IVC) filter (William Cook, Europe) with regard to insertion, efficiency, ease of retrieval, and any associated complications. A retrospective review was performed of 115 patients (41 female, 74 male, mean age 47.97 years) who underwent Cook Celect IVC filter insertion between December 2005 and October 2007. Filter insertion was successful in all patients. Of the 115 filters inserted, 57 have been successfully retrieved (49.6%) to date. The successful retrieval rate from attempted retrieval was 93.4%. The mean dwell time of successfully retrieved filters was 114.9 days (range 14-267 days). Failed retrievals were due to a thrombosed vena cava (n = 1) and endothelialisation of the filter (n = 3). In the failed retrieval group the mean implantation time was 142 days (range 78-211 days). While this is the first retrospective clinical study on the Cook Celect filter, results to date are promising. We demonstrated an efficacious filter with a high successful retrieval rate of 93.4% and a low complication rate. The filter was assessed with extended dwell times (range 14-267 days). Failed retrieval secondary to hook endothelialisation continues to be an issue with this filter. We recognize that a limitation of our study was the lack of systematic follow-up for clinically silent complications. Further studies to evaluate longer term outcomes and effectiveness of this filter are warranted.
本研究的目的是评估我们在使用可回收的库克Celect下腔静脉（IVC）滤器（威廉·库克公司，欧洲）方面在植入、有效性、回收难易程度以及任何相关并发症方面的经验。对2005年12月至2007年10月期间接受库克Celect IVC滤器植入的115例患者（41例女性，74例男性，平均年龄47.97岁）进行了回顾性研究。所有患者的滤器植入均成功。在植入的115个滤器中，截至目前已有57个成功回收（49.6%）。尝试回收的成功回收率为93.4%。成功回收的滤器的平均留置时间为114.9天（范围14 - 267天）。回收失败的原因是腔静脉血栓形成（n = 1）和滤器内皮化（n = 3）。在回收失败组中，平均植入时间为142天（范围78 - 211天）。虽然这是关于库克Celect滤器的第一项回顾性临床研究，但迄今为止的结果很有前景。我们证明了该滤器有效，成功回收率高，为93.4%，并发症发生率低。对该滤器进行了较长留置时间（范围14 - 267天）的评估。由于钩状内皮化导致的回收失败仍然是该滤器的一个问题。我们认识到我们研究的一个局限性是缺乏对临床无症状并发症的系统随访。有必要进行进一步研究以评估该滤器的长期结果和有效性。
