Official Title

A Multicentre, Prospective, Observational Study on the Predictive Role for Recurrence of D-dimer Levels Measured During and After Anticoagulation in Patients With a First Venous Thromboembolism Episode (the PROLONG-II Study)

Objective

The Prolong-Two study aims at assessing the predictive role for recurrence of D-dimer levels measured: a) during anticoagulation, b) one month after its withdrawal and c) periodically during follow up
