CIRSE established a registry of retrievable filter use with the primary aim of determining the success of IVC Filter retrieval and associated complications. Secondary endpoints included filter indications, imaging strategies before retrieval, filter dwell times, and anticoagulation status. A web-based electronic registry was hosted between 01/12/2010 and 30/06/2012. Data entry occurred at the date of IVC filter retrieval and included items such as filter type, indication for filter insertion, access route, dwell time, retrieval success, complications, reasons for failed retrieval, and anticoagulation status. 671 filter retrievals were entered (male:female 333:295, mean age 55, median 57). Retrieval data were not entered in 43/671 leaving 628 patients for analysis. The 4 commonest retrievable filters used were the Celect in 182 patients, the OPTEASE in 161, ALN in 120, and Gunther Tulip in 98. Filters were inserted for absolute indications 40%, relative indications in 31%, and prophylactic in 24%, with 5% missing. Mean filter dwell time was 90 days. Filters were successfully retrieved in 576/628 patients (92%). The mean dwell time for successful retrievals was 85 days versus 145 days for unsuccessful retrievals (p = 0.001). Major complications occurred in 2 patients (0.03%). In summary, the CIRSE retrievable filter registry demonstrates a retrieval rate of 92% across a range of filter types, with a low major complication rate, reflecting current practice. There is an increase in trend of retrievable filter use for relative and prophylactic indications.
欧洲血管与介入放射学会（CIRSE）建立了一个可回收滤器使用登记处，其主要目的是确定下腔静脉滤器回收的成功率及相关并发症。次要终点包括滤器植入指征、回收前的成像策略、滤器留置时间和抗凝状态。一个基于网络的电子登记处于2010年12月1日至2012年6月30日期间启用。数据录入在进行下腔静脉滤器回收之日进行，录入项目包括滤器类型、滤器植入指征、入路、留置时间、回收成功情况、并发症、回收失败原因以及抗凝状态。共录入了671例滤器回收情况（男性：女性为333:295，平均年龄55岁，中位数57岁）。671例中有43例未录入回收数据，剩余628例患者用于分析。使用最多的4种可回收滤器分别是：182例患者使用Celect滤器，161例使用OPTEASE滤器，120例使用ALN滤器，98例使用Gunther Tulip滤器。因绝对指征植入滤器的占40%，相对指征的占31%，预防性植入的占24%，5%情况不明。滤器平均留置时间为90天。628例患者中有576例（92%）成功回收滤器。成功回收的平均留置时间为85天，未成功回收的为145天（p = 0.001）。2例患者（0.03%）出现严重并发症。总之，CIRSE可回收滤器登记处显示，各类滤器的回收率为92%，严重并发症发生率低，反映了当前的实际情况。用于相对指征和预防性指征的可回收滤器使用呈上升趋势。
