Outcomes in Endovascular Management of May Thurner Syndrome Without Access to IVUS in a Latin American Cohort: A Retrospective Study.

Introduction and ObjectiveMay Thurner Syndrome (MTS) is a condition characterized by left iliofemoral vein compression, often leading to lower limb symptoms and complications. This study aimed to evaluate the outcomes of endovascular management for symptomatic, non-thrombotic MTS in a Latin American population.MethodsA retrospective cohort study analyzed 43 patients with MTS who underwent endovascular stenting and anticoagulation between 2018 and 2023 in Bogotá, Colombia. Clinical data, including demographics, symptoms, and comorbidities, were collected. Perioperative outcomes, such as procedure time, complications, and length of stay, were recorded. Postoperative follow-up included stent patency, symptom resolution, and the occurrence of complications.ResultsEndovascular management demonstrated high efficacy, with 83.7% of patients achieving symptom resolution and 100% stent patency at 6 months. No major complications were reported. The average procedure time was 52.6 minutes, and patients were discharged within 1 day of the procedure.ConclusionEarly intervention with endovascular embolization is crucial for patients with MTS and symptomatic pelvic varices. This approach offers a safe and effective solution for managing the condition and preventing complications. The presence of symptoms should be considered an indication for endovascular intervention, rather than waiting for thrombosis development.
