Objectives: State of the art of antithrombotics and their use recommendations during pregnancy.
Methods: A review
Results: Aspirin and heparins remain the safest molecules during pregnancy, and oral anticoagulants are still used for mechanical valves. Heparinoids are the methods of choice in case of heparin-induced thrombopenia but other molecules could find their place: fondaparinux at first and possibly the direct thrombin inhibitors. Thrombolysis may be used in case of life-threatening incident. At present, the new oral forms can not be used during pregnancy
Conclusions: During pregnancy, all antithrombotics, except the oral forms, can be used, but the low molecular weight heparins replacing the unfractionated ones in the treatment and prevention of venous thromboembolism remain the treatment of choice.
