An inferior vena cava (IVC) filter became embedded within the IVC of a 45-year-old man after prolonged implantation. Because of incorporation of the filter legs within the caval endothelium, the filter was densely adherent and could not be sheathed using standard retrieval methods. In this patient, the authors performed percutaneous filter retrieval using an excimer laser sheath technique for circumferential ablation of dense fibrotic tissue between the filter and IVC. Endovascular laser ablation allowed facile separation of the filter from the IVC, without tearing of the tissues, and the filter was removed successfully without complication.
