E.5 End points |
E.5.1 | Primary end point(s) |
Percentage of patients with PTS characterized by a Villalta-Prandoni score ≥ 5 on two consecutive occasions of at least 3 months apart, or presence of a venous ulcer one year following the acute thrombotic event. (Villalta-Prandoni: score 5-9 = mild PTS, score 10-14 = moderate PTS, score ≥ 15 or venous ulcer = severe PTS) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Month 3, 6, 12, 24, 36, 48 after inclusion |
|
E.5.2 | Secondary end point(s) |
The Health Related Quality of Life (HRQOL) based on scorings on SF-36, EuroQOL-5D, VEINES-QOL/Sym and pain disability index (3, 6 and 12 months after the event) Late PTS during follow-up Recurrent venous thrombo-embolisms (VTE): DVT (measured by Compression ultra sonography (CUS)) or pulmonary embolism (PE) during follow-up Clot lysis, patency (measured by MRA-Vasovist during baseline visit and after 12 months, which shows the occlusion percentage of all visualized veins). Measurements of markers of coagulation (INR, fibrinogen, aPTT) and inflammation (CRP, leucocytes) at the baseline visit, during treatment visit and 12 months after the event. Safety outcome: Bleeding events during anticoagulant therapy.
