What are relative contraindications to IVC filter placement?
The decision to place a permanent medical device should be made on a case-by-case basis and only after careful deliberation of the patient’s history. One relative contraindication to filter placement is septic emboli or active bacteremia because of the theoretic risk of infectious seeding of the filter. IVC filters are not routinely placed in adolescents or pregnant women. A severe hypercoagulable state or a history of IVC thrombus may preclude filter placement because of the risk of complete IVC thrombosis.
