title: Duplicate inferior vena cava filters: more is not always better.
abstract: Duplication of the inferior vena cava (IVC) has been reported in literature. This achieves clinical significance in the setting of lower extremity venous thromboembolism with a contraindication for anticoagulation. We describe a case of lower extremity deep vein thrombosis with duplicate IVC. Anticoagulation was contraindicated in this case leading to successful treatment with double IVC filters. We conducted a PubMed search for all current English language published literature, where filters were placed in the presence of duplicate IVC. We suggest that patients with deep vein thrombosis should have an accurate assessment of venous anatomy before IVC filter placement. Duplication of IVC, although rare, should be considered as this has management implications.
