AbstractThe present report describes the safe retrieval of caudally migrated optional inferior vena cava (IVC) filters with significant IVC penetration. Three patients had optional IVC filters placed for deep vein thrombosis/pulmonary emboli and contraindications for anticoagulation. Subsequent imaging showed caudal migration and penetration of the filter legs through the IVC wall. All filters were removed without major complications. One patient experienced abdominal pain after filter removal, which required no treatment. Caudal migration of optional filters with IVC wall penetration by the filter legs may be more common with new filter designs in which the secondary and primary struts are separated.Copyright (c) 2010 SIR.
