%X <B>OBJECTIVE: </B>To assess the efficacy and safety of rivaroxaban compared to warfarin after inferior vena cava (IVC) filter implantation.<BR><B>METHODS: </B>This retrospective analysis includes data from 100 patients with deep vein thrombosis (DVT) who underwent IVC filter implantation due to a free-floating thrombus (n = 64), thrombus propagation (n = 8), or acute bleeding (n = 8) on therapeutic anticoagulation, catheter-directed thrombolysis (n = 8), or had previously implanted filter with DVT recurrence. Patients were treated with warfarin (n = 41) or rivaroxaban (n = 59) for 3-12 months. Symptomatic venous thromboembolism (VTE) recurrence and bleeding events were assessed at 12 months follow-up.<BR><B>RESULTS: </B>Three (7.3%) cases of VTE recurrence without IVC filter occlusion occurred on warfarin and none on rivaroxaban. The only (2.4%) major bleeding occurred on warfarin. Three (5.1%) clinically relevant non-major bleedings were detected on rivaroxaban. No significant differences existed between groups when full and propensity scores matched datasets were compared.<BR><B>CONCLUSIONS: </B>Rivaroxaban seems not less effective and safe than warfarin after IVC filter implantation.
