Brief Summary:
This clinical trial will investigate the hypothesis that D-Dimer testing can be successfully used to tailor the duration of OAT in patients after an unprovoked episode of deep venous thrombosis (DVT) using a prospective, randomized, and controlled design.
Detailed Description:
After a first episode of acute deep venous thrombosis (DVT) the risk of recurrence is relatively high and clinical consequences are important. Therefore, secondary prophylaxis using oral anticoagulant treatment (OAT) is usually established in these patients. This treatment very effectively reduces the risk of recurrences but induces an increased risk of bleeding. Major bleeding complications can be expected in \~2% patient-years. Therefore, current recommendations limit OAT to a period of 3 to 12 months. After stopping of OAT, however, \~10 % of patients with an initial episode of unprovoked DVT will develop a recurrent event within 1 year. This group of patients may benefit from prolonged OAT. The results of 2 independent observational studies showed a significantly higher risk of recurrence in patients showing increased levels of D-Dimer after withdrawal of OAT. D-Dimer is a biomarker that indicates fibrin formation followed by fibrinolysis. Based on these data we hypothesize that D-Dimer testing can be successfully used to tailor the duration of OAT in patients after an unprovoked episode of DVT. This clinical trial will investigate this hypothesis using a prospective, randomized, and controlled design.
