Asymptomatic penetration of the inferior vena cava (IVC) wall with retrievable filters is not uncommon. Occasionally, this can be a cause for morbidity, and rarely for mortality. We present a case of duodenocaval fistula, secondary to penetration from a strut of retrievable IVC filter that presented as lower gastrointestinal bleeding and discuss the subsequent management. Although newer generation retrievable filters provide a longer time for retrieval, they are associated with an increased incidence of IVC wall penetration, caudal migration, and occasionally symptomatic presentation, thereby necessitating surgical intervention. Close follow-up is warranted, and prompt retrieval of such devices should be done when their use is no longer indicated.
可回收滤器无症状穿透下腔静脉（IVC）壁的情况并不少见。偶尔，这可能导致发病，极少情况下会导致死亡。我们报告一例十二指肠腔静脉瘘病例，继发于可回收IVC滤器支柱的穿透，表现为下消化道出血，并讨论后续治疗。尽管新一代可回收滤器提供了更长的回收时间，但它们与IVC壁穿透、尾端迁移的发生率增加有关，偶尔还会出现症状性表现，因此需要手术干预。有必要进行密切随访，当不再需要使用此类装置时，应及时将其取出。
