Percutaneous retrieval of an inferior vena cava filter causing right ureter obstruction.

Retrievable inferior vena cava filters (IVCFs) are known to provide safe and effective pulmonary embolism protection when used appropriately. Long-term complications have been reported over the past 10 years, including vena cava perforation, filter migration, strut fracture, and injury to adjacent structures. This article describes the case of a 44-year-old woman who presented with right ureteral obstruction from strut impingement by a Bard Recovery IVCF (Tempe, AZ, USA). The filter had been in place for 6 years, and the authors were successful in retrieving it using a percutaneous endovascular approach, despite an unexpected chronic right innominate vein occlusion. In addition to highlighting the technical feasibility of long-term retrieval, this case underscores the importance of an IVCF registry to improve retrieval rates. This close monitoring and timely retrieval of filters may help prevent serious long-term complications.
