Operative retrieval has not been necessary in our experience, though interest has been expressed by other surgeons. Specifically, during removal the hooks of the filter may become attached to adjacent structures, making manipulation and eventual extraction difficult. Because the occasion for late removal of a misplaced filter may arise, we have developed this method using readily available materials. We anticipate that this technique will be most useful for removal of filters that have been in place for more than 7 days. A method to retrieve filters in place less than 1 week has already been reported [4]. We have found the technique quite satisfactory in experimental animals.
根据我们的经验，手术取出并非必要，不过其他外科医生对此表示了兴趣。具体而言，在取出过程中，滤器的钩子可能会附着在相邻结构上，导致操作和最终取出困难。由于可能会出现后期取出误置滤器的情况，我们利用现成的材料开发了这种方法。我们预计，这项技术对于取出已放置超过7天的滤器最为有用。一种取出放置时间少于1周滤器的方法已经有报道[4]。我们发现在实验动物中这项技术非常令人满意。
