TrapEase vena cava filter: a case of filter migration and pulmonary embolism after placement.

Inferior vena cava filters provide an alternative method of protection against pulmonary embolism in situations where anticoagulation either fails or is contraindicated. These filters are easily placed, with a relatively minor risk of complications. Currently, we know of only one reported case of filter migration using the TrapEase filter. We present a case report of a migrating TrapEase filter, as well as pulmonary embolism after TrapEase filter placement. This complication developed in a 31-year-old trauma patient who developed bilateral popliteal deep vein thromboses and an initial pulmonary embolus while on low molecular weight heparin.
