"Caval Reconstruction for Lower-Extremity Sarcoma Metastasis Trapped within Inferior Vena Cava Filter".

This report describes the management of a hematogenously spread metastasis from a lower-extremity sarcoma found trapped within an inferior vena cava (IVC) filter. Although endovascular techniques for treating thrombosed IVC filters are successful in a majority of cases, the malignant nature of this lesion required a novel approach. In this unique case, the segment of infrarenal IVC with the thrombosed filter was resected and reconstruction performed with an interposition prosthetic graft. There were no early or late complications, and the patient remains clinically free of recurrence at 24-month follow-up.
