Endovascular therapy can eliminate chronic venous obstruction and is hypothesized to reduce the severity of post-thrombotic syndrome. Methods: We randomly assigned 225 patients with moderate or severe post-thrombotic syndrome and imaging-confirmed iliac-vein obstruction to receive endovascular therapy (iliac-vein stent placement and enhanced antithrombotic therapy) plus standard post-thrombotic syndrome care or standard post-thrombotic syndrome care alone. The severity of post-thrombotic syndrome at 6 months (the primary outcome) was assessed with the validated Venous Clinical Severity Score (VCSS) tool (scores range from 0 to 30, with higher scores indicating more severe post-thrombotic syndrome) by evaluators who were unaware of the group assignments. Key secondary outcomes included venous disease–specific and overall quality of life. Results: At 6 months, the severity of post-thrombotic syndrome was lower in the endovascular-therapy group than in the no-endovascular-therapy group (mean [±SD] VCSS, 8.1±5.1 vs. 10.0±4.9; adjusted difference, −2.0; P=0.001). Venous disease–specific quality of life as assessed with the Venous Insufficiency Epidemiological and Economic Study Quality of Life questionnaire was better in the endovascular-therapy group than in the no-endovascular-therapy group at 6 months (adjusted difference, 14.5 points; P<0.001), as was overall quality of life as assessed with the Medical Outcomes Study 36-Item Short-Form Health Status Survey physical component summary score (adjusted difference, 6.1 points; P<0.001); scores on both tools range from 0 to 100. Through 6 months, bleeding was more common in the endovascular-therapy group than in the no-endovascular-therapy group (in 11.6% vs. 3.6% of the patients; P=0.03). Conclusions: Among patients with moderate or severe post-thrombotic syndrome and iliac-vein obstruction, endovascular therapy led to less severe post-thrombotic syndrome and better health-related quality of life than standard care over a 6-month period but with a higher risk of bleeding.
