Residual thrombosis on ultrasonography to guide the duration of anticoagulation in patients with deep venous thrombosis: a randomized trial.

BACKGROUND The optimal duration of oral anticoagulant therapy in patients with deep venous thrombosis (DVT) of the lower extremities remains uncertain. OBJECTIVE To assess whether tailoring the duration of anticoagulation on the basis of the persistence of residual thrombi on ultrasonography reduces the rate of recurrent venous thromboembolism (VTE… CONTINUE READING
