A retrospective cohort study assessing the incidence of inferior vena cava (IVC) occlusion following prophylactic IVC filter insertion: Is anticoagulation necessary during filter dwell?

•This study assessed the incidence of IVC thrombosis following prophylactic filter insertion at a tertiary trauma centre.•124 patients were included and were no cases of IVC occlusion in any of the groups.•The use of therapeutic anticoagulation during IVC filter dwell should not be dictated by the presence of an IVC filter but rather by the presence of a related thrombosis event.
