Inferior vena caval diameters were measured in 65 patients with Kimray-Greenfield (KG) inferior vena caval filters. The measurements were made at the distal tips of the filter tines on postplacement radiographs. Magnification corrections were made using the filter tine lengths as references. The overall mean diameter was 20 mm, the range was 13 to 30 mm, and the standard deviation was 3 mm. Two cavae (3%) were more than 28 mm in diameter. A previous in vitro study has shown that in venae cavae of this size there is a significant risk of reduced clot-capturing ability with the KG filter and migration with the Mobin-Uddin filter. Thus it is important to evaluate vena caval diameter by cavography prior to filter placement.
对65例植入金瑞-格林菲尔德（KG）下腔静脉滤器的患者测量了下腔静脉直径。测量是在滤器放置后X线片上滤器尖端的远端进行的。使用滤器尖端长度作为参考进行放大校正。总体平均直径为20mm，范围为13至30mm，标准差为3mm。两条下腔静脉（3%）直径超过28mm。先前的一项体外研究表明，对于这种尺寸的下腔静脉，使用KG滤器存在血栓捕获能力降低以及使用莫宾-乌丁滤器存在移位的显著风险。因此，在放置滤器之前通过腔静脉造影评估下腔静脉直径很重要。
