The fact that many inferior vena cava filters (IVCF) in trauma patients are not being removed has been described numerous times in the literature, but nobody really gives a reason why. This case presents a young patient who prophylactically received an optional IVCF after sustaining severe multitrauma. He had a failed retrieval 8 weeks post insertion and consequently was lost to follow-up before a second removal attempt was performed. Institutions inserting IVCF should establish guidelines for following up patients receiving prophylactic IVCF.
