D-dimer to Establish Duration of Anticoagulation After Venous Thromboembolism

Summary

The optimal duration of oral anticoagulant treatment in patients with idiopathic venous thromboembolism is still uncertain. The present study addresses the possible role of the D-dimer test in assessing the need for continuation of anticoagulation.The study aims at assessing whether D-dimer assay may have a role in guiding the duration of anticoagulation in these patients
