Answer

Answer

DVT or PE in a patient who has a complication of anticoagulation therapy accounts for 6-18% of IVC filter placements.

Anticoagulation therapy is not without potential complications; it is associated with a mortality of 5-12%, and therapy may have to be discontinued in as many as 18% of patients because of hemorrhage. Anticoagulation with heparin is also associated with immune-mediated heparin-induced thrombocytopenia (HIT) in 1-3% of treated patients. Approximately 25% of patients with HIT develop new venous and/or arterial thrombotic events, including PE.
