Abstract
Venous thromboembolism (VTE) is a common cause of morbidity and mortality. Although most patients can be managed safely with anticoagulation, inferior vena cava filters (IVCFs) represent an important alternative to anticoagulation in a small subset of patients. IVCF use has expanded exponentially with the advent of retrievable filters. Indications for IVCFs have liberalized despite limited evidence supporting this practice. Because indiscriminate use of IVCFs can be associated with net patient harm, knowledge of the risks and benefits of these devices is essential to optimal evidence-based practice. Patients with acute VTE and absolute contraindications to anticoagulation or major complications from anticoagulation are universally agreed indications for IVCFs. However, the reliance on IVCFs for primary VTE prophylaxis in high-risk patients is not substantiated by the available literature. This review examines trends in IVCF use, practice-based recommendations on IVCF use in various clinical scenarios, complications associated with indwelling IVCFs, and indications for IVCF retrieval.
