a Venography of IVC before first removal attempt shows a tilted Celect filter with one leg protruding outside the IVC. b A repeat venography 8 years later shows a more tilted filter with a deeply embedded filter tip and two legs outside the IVC. c A lateral view confirms one loop on each side of the filter tip. d A third loop was created using a reversed shape catheter an exchange length guidewire and a snare. e Photography after explantation illustrates the three loops around different legs and arms of the filter. f Venography immediately after filter removal shows a contrast pocket at the location of the former filter tip location. g A control venography 6 weeks later reveals a smooth IVC with only a mild stenosis at the level of previous filter location
