Exercise Tolerance After Venous Recanalization for Post-thrombotic Syndrome
France22 participantsStarted 2023-04-17
Plain-language summary
Post-thrombotic syndrome (PTS) is the most frequently observed chronic complication of deep vein thrombosis (DVT), with an estimated cumulative incidence of 20-50%. Endovascular venous recanalization with angioplasty and stenting of obstructive lesions is the recommended treatment option to reduce or correct the symptoms of DVT. However, its impact on the physical capacity and breathlessness of patients has not been fully demonstrated. The heterogeneous evidences of clinical improvement is probably related to the presence or absence of collateral veins developed in these patients with proximal venous obstruction (iliac or iliofemoral with or without inferior vena cava involvement), which ensure the cardiac venous return. The aim of this study is to compare changes in maximal oxygen uptake after endovascular venous recanalization in DVT patients and to evaluate the hemodynamic, respiratory and muscular improvement induced by the restoration of venous flow in the occluded segments.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
