Surgical anteriorization of the left common iliac vein results in improved venous outflow and quality of life for May-Thurner syndrome

May-Thurner Syndrome (MTS) or left iliac vein (LIV) compression occurs when the left common iliac vein is compressed by the right common iliac artery, leading to a venous outflow obstruction. This obstruction can cause venous hypertension, causing lower extremity swelling, discoloration, pelvic congestion, and venous ulcerations. The standard surgical treatment for MTS is endovascular venous stent placement. In a small single-center sample, surgical anteriorization of the left common iliac vein was used to treat symptomatic left common iliac vein compression in younger patients, alleviating their symptoms, and can be considered an alternative treatment.
