Inferior vena cava filter placement at bedside using computed tomography scan information: a new technique for accurate deployment.

Background: An inferior vena cava filter (IVCF) is indicated for the prophylaxis of pulmonary embolism where anticoagulation is contraindicated. The majority of these filters are placed using fluoroscopy and venogram. We hypothesized that a computed tomography (CT) scan of the abdomen and pelvis provides sufficient information for successful deployment of an IVCF at bedside without the need for any further imaging during the procedure.
