Migration of Inferior Vena Caval filter to the Right Atrium: Is any model free of this complication?

The use of inferior vena caval (IVC) filters has been an accepted method for preventing pulmonary embolism, especially in cases where there are contraindications to anticoagulation. However, these filters have numerous potential complications some of which could be life threatening like, thrombosis and migration of the filter. The "Antheor" filter was designed to prevent this complication. Unfortunately, we encountered one patient where it has been unsuccessful in this regard. We therefore, believe that there is no ideal filter and the selection of a filter requires thorough knowledge of the limitations of individual brand.
