[Anticoagulant treatment in pulmonary embolism : how to initiate and how to pursue ?].

Pulmonary embolism (PE) is associated with significant morbidity and mortality in the absence of properly prescribed anticoagulant treatment. Direct oral anticoagulants (DOACs) are currently the anticoagulant treatment of first choice. The quality of anticoagulation in the acute phase of PE is a major determinant of patients' prognosis. The dose regimens for the initiation phase must therefore be rigorously respected to ensure the efficacy of the treatment. For the maintenance phase, the reduced doses used in atrial fibrillation are not applicable in venous thromboembolism (VTE) except for edoxaban. Finally, for long-term secondary prevention in patients at risk of VTE recurrence, reduced dose DOACs are currently a very interesting option in terms of benefit-risk balance for the majority of patients.
