Inferior Vena Cava Filter Malposition in a Paraspinal Vein

Inferior vena cava (IVC) filtration is used in patients with deep venous thrombosis and/or pulmonary embolism who fail or are unfit for anticoagulation therapy. In the past, malposition was a relatively common event when vena cava filters were placed by surgeons without imaging guidance, especially when the internal jugular veins were used for access. Currently, complications are uncommon when filters are placed by interventional radiologists and malposition is exceedingly rare.
