Case Report

Removal of Vena Caval Filter at 224 Days

Authors: John C. Lipman, MD, FSIR


Patients at risk of pulmonary embolism usually receive anticoagulants, which are contraindicated in trauma victims. A woman with extensive deep venous thrombosis after a vehicle accident had a nitinol Recovery Filter inserted prophylactically. After her recovery, she requested filter removal because of her intention to become pregnant. The filter was removed percutaneously without difficulty 224 days after implantation.

Key Points

* Prophylactic placement of a vena caval filter in patients at high risk of pulmonary embolism has been controversial.

* Certain optional vena caval filters may remain in place safely for extended periods.

* The benefit of inferior vena cava filtration with a removable filter is a significant step in the prevention of pulmonary embolism.
