Problem studied: Post thrombotic syndrome. Preventive intervention: elastic compression stockings (ECS). Patients studied: patients after an acute event of DVT. Current practice is to prescribe ECS for 24 months after an event of acute DVT. It is currently not clear whether all patients benefit to the same extent from ECS therapy, or what the optimal duration for individual patients should be. Keywords: Elastic Compression Stockings, Deep Venous Thrombosis, Post Thrombotic Syndrome.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The occurrence of PTS at 24 months after the event of acute DVT (the observers will be blinded to the allocated treatment arm). | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Health Related Quality of Life (HRQOL), will be measured by questionnaires SF-36, EuroQol-5D, Veines-Qol Dutch translated (time point baseline, 3, 6, 12 and 24 months); 2. Recurrent venous thrombosis (time point 24 months); 3. Mortality due to venous thrombosis (time point 24 months); 4. Costs will include direct costs (e.g. medical therapy) and indirect costs (e.g. travel) and will be measured by case record forms, hospital data and 5 retrospective cost-questionnaires (time point 3, 6, 12, 24 months); 5. Patient Preference will be elicited by conducting a discrete choice experiment (DCE) at time point 12 months. | — |
