Anterioposterior view of snare manipulation to remove the filter. The patient was referred 90 days after implantation for filter removal. The cavogram showed a patent filter without tilt or filter struts vena cava penetration. A 20 mm snare was deployed over the filter hook. Since the filter was hooked, snare wire was pinned while the 13Fr catheter was advanced over the snare wire to collapse the filter. The filter was pulled into the 13fr catheter for extraction. The post extraction cavogram showed no abnormality.
