Inferior vena cava filter retrieval is a procedure used to remove a filter that was placed in the inferior vena cava to prevent pulmonary embolism in patients with deep vein thrombosis (DVT). The procedure is typically performed after the patient's risk of clot formation has decreased and the filter is no longer needed. It involves inserting a catheter to retrieve the filter, restoring normal blood flow in the affected vein.

This procedure helps prevent long-term complications associated with a permanent filter, such as filter migration or occlusion of the vena cava.
