We report the case of a 47-year-old man who experienced a pulmonary embolism associated with a femoral thrombus after a traumatic intracranial haematoma and had caval interruption using a new generation endovascular percutaneous filter. A shock occurred soon after the procedure, associated with inferior cava system inflation related to a filter thrombosis. This is a rare complication since the cessation of surgical cava interruptions. The situation became stable after intensive volume expansion. This report underlines the risk of complication associated to vena cava interruption despite the use of new generation filters and the significance of mechanical measures in prevention of thrombosis when anticoagulants are contraindicated.
