Brief Summary:
The purpose of this study is to assess efficacy and safety of optional vena cava filter implanted 3 months in prevention of recurrent pulmonary embolism in patients presenting with acute pulmonary embolism associated with thrombotic risk factors
Detailed Description:
Pulmonary embolism is a common pathology, which could be fatal (about 10 000 death/year in France). It mainly originates from a deep vein thrombosis. In order to reduce mortality, prevention of new or recurrent PE is a major therapeutic aim. Only one randomised trial (PREPIC) assessed the interest of a vena cava filter in patients treated by anticoagulant treatment for a deep vein thrombosis (DVT). Results show a significant 50 % reduction of the embolic risk with the filter. This benefit occurs from the first days, but are counterbalanced by a long-term increasing risk of recurrent DVT. The filter appears promising in patients with a high risk of PE, for exemple the elderly, presenting with a thromboembolic history, cancer, heart failure or respiratory insufficiency, or a recent PE. Moreover, retrievable filters, which may be either left in place permanently or retrieved after some days or weeks, could limit the filter thrombosis risk.
The aim of PREPIC 2 study is to assess, in a multicenter randomised trial, efficacy and safety of a retrievable vena cava filter implanted 3 months versus no filter in 400 patients treated with anticoagulant drugs for a symptomatic PE associated with at least one thrombotic risk factor. A clinical follow-up will be performed at 6 months. The primary outcome is the incidence of recurrent PE at 3 months, including symptomatic and fatal PE. It will be adjudicated by an independent committee, blinded to patients' allocation.
This study will assess the benefit risk ratio of the retrievable filter for the prevention of recurrent PE, without increasing the thrombotic risk and the disadvantage due to post thrombotic syndrome.
