Serial repositioning of a Günther tulip retrievable inferior vena cava filter in a pediatric patient.

We report an 11-year-old boy who required inferior vena cava (IVC) filtration for a prolonged period of time. A retrievable IVC filter was placed and repositioned three times, providing a total of 60 days of IVC filtration. The filter was removed when his risk of pulmonary embolus had decreased substantially. This is a relatively uncommon practice in the pediatric population. The technique is presented, and the available literature is reviewed.
