108 filters were made permanent, 13 of these were due to failed retrieval (these were included in the calculation as failed retrievals) In 7 of these 13 failed retrievals, no advanced manoeuvres were attempted. The mean dwell time for these failed retrievals were 63 days for GT filters, 73 for Celect and 81 for ALN filters. At greater dwell times advanced maneuvers become essential to ensure high successful retrieval rates are maintained. This is supported by Kuo et al. which reported 100% successful retrieval in a series of 50 patients where advanced manoeuvres were performed after standard methods had previously failed.[15] In a review of advanced techniques, Desai et al. illustrated that after 7 months of filter being in situ, the chances of the standard retrieval methods failing is high, with a calculated risk of 40.9% which continues to rise with increasing dwell time.[16] This evidence underscores the importance of both attempting advanced maneuvers when standard methods fail, as well as the necessity of reducing mean dwell time which can be done with regular follow up.
