Inferior vena cava filter-associated abnormalities: MDCT findings.

Abstract

Deep venous thrombosis from the pelvis or lower extremities has significant morbidity, and subsequent pulmonary embolism has a high mortality rate. Immediate anticoagulation in patients with deep venous thrombosis is crucial in preventing this lethal complication. However, in patients with contraindications for or failure of anticoagulation, inferior vena cava filters reduce mortality by decreasing the incidence of pulmonary embolism. In this review, we discuss the various pathologic abnormalities related to inferior vena cava filters, as seen on MDCT images.
