We have described a case of migration of a Kim-Ray Greenfield umbrella from the inferior vena cava to the heart for unknown reason. The umbrella was surgically removed and the patient recovered fully. This complication has not been previously reported. Despite this complication, we believe that the Kim-Ray Greenfield umbrella, when placed with particular attention to technique, effectively prevents pulmonary emboli and offers minimal associated morbidity.
我们描述了一例Kim-Ray Greenfield滤器不明原因地从下腔静脉迁移至心脏的病例。该滤器通过手术取出，患者完全康复。此前尚未有此并发症的报道。尽管出现了这一并发症，但我们认为，在特别注意技术操作的情况下，Kim-Ray Greenfield滤器能有效预防肺栓塞，且相关发病率极低。
