Materials and Methods: This is a prospective randomized study, conducted in three centers between April 2020 and May 2021. A total of 115 participants were randomized, of which 15 participants were excluded for various reasons. Each group of 50 participants was finally assigned a type of filter (Celect n = 50 and ALN = 50). Tilt angles at placement and retrieval, rates of overall filter retrieval, complications, complex retrieval, and clinical follow-up at 12 months were compared. Results: One hundred participants (59 men and 41 women) were included. The mean age was 62.4 ± 13.3, with no significant differences between both groups (p 0.503). The mean of dwelling time was 44.7 ± 93 days. (p 0.520) Filter retrieval was successful in all participants (100%). The main complication in CT prior to removal was tilt >15° (31%) and filter tip embedment (16%). No significant differences were observed in the type of retrieval (standard or complex) between both filters (p 0.24); however, fluoroscopy time was significantly longer in the complex removal of the Celect filter: 29.1 ± 12 min vs. 17.5 ± 10.3 (p 0.005). After one year, no recurrent pulmonary embolism was observed in both types of filters. Conclusions: The ALN filter had a significantly lower rate of tip and filter tip embedding, with no differences in complexity or removal success rate. There were significant differences in the fluoroscopy time consumed for standard and complex retrievals between both filters, with less time for the ALN filter.
