ACR Appropriateness Criteria® Radiologic Management of Venous Thromboembolism-Inferior Vena Cava Filters.

Venous thromboembolism (VTE)-deep vein thrombosis and pulmonary embolism-is a common cause of morbidity and mortality. The mainstay of VTE prophylaxis and therapy is anticoagulation. In select patients with VTE, inferior vena cava (IVC) filters are used to prevent pulmonary embolism by trapping emboli as they pass from the lower extremity venous system through the IVC. These guidelines review the indications for placement of IVC filters in acute and chronic VTE, as well as the indications for retrieval of implanted IVC filters. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.
