Novel Techniques for Removal of Embedded Inferior Vena Cava (IVC) Filters Reduce Risk of Long-Term Complications

Technique for Removal of Embedded Inferior Vena Cava (IVC)

With the loop snare forcefully closed around the filter legs, the metal guide is pulled back with the filter into the sheath. The captured filter legs fold in half and the filter apex begins to invert (arrow).

Retrievable IVC filters are used to treat patients temporarily for pulmonary embolism (PE) prophylaxis, including those facing prolonged bedrest following lower-limb surgery. The devices may be removed to prevent the risk of long-term complications once there is no immediate risk of thromboembolism, with medical management superseding cardiovascular interventions.¹ Complications can include filter fracture, embolization, caval penetration, and, ironically, an increased incidence of recurrent deep vein thrombosis after filter placement.¹ Regular patient follow-up is critical for optimal outcomes, along with periodic chart reviews and multiple attempts to contact patients.¹ Inferior vena cava filters, particularly those in place for many months or years, can embed themselves in surrounding tissue, but novel techniques can often succeed in even the most complicated IVC filter removal cases.
