Inferior vena cava filter (IVCF) is widely used as a complementary medical device for venous thromboembolism (VTE) treatment. Although complications of IVCF placement are rare, tilting, migration and penetration of IVCF or perforation of IVC have been reported. In addition to these complications, there are concerns about fracture or thrombus of IVCF, especially in the case of permanent placement. Therefore, the current guidelines recommend that a retrievable IVCF should be selected and an insertion period should be minimized. We report a case of IVCF thrombus due to venous thromboembolism after seven years of IVCF insertion under continuous warfarin therapy. Warfarin therapy were discontinued and replaced by rivaroxaban. IVCF thrombus disappeared one month later.
