Echo Doppler (ED )Score and D-dimer (DD) Level in the Evaluation of VTE Recurrence After Anticoagulant Treatment Cessation

Study of Predictive Echo Doppler Score and D-dimer Level in Evaluation of the Thromboembolic Event Recurrence After Anticoagulant Treatment Cessation.

The purpose of this trial is to perform a prospective multicentric study to determine predictive ED score and D-dimer level in the evaluation of the thromboembolic event recurrence after anticoagulant treatment cessation.

The patients are included in the study from the anticoagulant treatment cessation. An ED score and a blood sample are performed at this time and one month later. Then, the patients are followed up by phone for 2 years.

DDimer levels are centralized in University Hospital of Grenoble at the end of the study
