The Amplatz retrievable vena caval filter was designed in an attempt to decrease complications associated with the placement of Mobin-Uddin or Kimray-Greenfield filters. The design allows percutaneous retrieval, thus expanding application of the filter to situations requiring temporary prophylaxis against pulmonary embolism. Filters have been placed in 16 patients, nine (56%) for prophylactic purposes. All filters were easily inserted percutaneously. Complications occurred in three patients; these included complete thrombosis of the inferior vena cava below the filter, misplacement of one filter into the pericaval retroperitoneal tissue, and development of thrombus cranial to the filter. With the current introduction system, the possibility of filter misplacement has been essentially eliminated. No patient experienced symptoms suggestive of pulmonary embolism after filter insertion. One filter retrieval has been performed, with no complications.
安普拉斯可取出式腔静脉滤器的设计旨在减少与莫宾-乌丁或金雷-格林菲尔德滤器放置相关的并发症。该设计允许经皮取出，从而将滤器的应用扩展到需要临时预防肺栓塞的情况。已为16例患者放置了滤器，其中9例（56%）用于预防目的。所有滤器均通过经皮方式轻松插入。3例患者出现并发症；这些并发症包括滤器下方下腔静脉完全血栓形成、一个滤器误置入腔静脉周围腹膜后组织以及滤器上方血栓形成。使用当前的导入系统，滤器误置的可能性已基本消除。滤器插入后，没有患者出现提示肺栓塞的症状。已进行了一次滤器取出，无并发症。
