Endovascular treatment of pelvic congestion syndrome caused by May-Thurner syndrome

May-Thurner syndrome (MTS) refers to compression of the left common iliac vein (CIV) by the common iliac artery. Although this is typically manifested as acute left lower extremity deep venous thrombosis, MTS is a rare cause of pelvic congestion syndrome. A 41-year-old girl presented with a 2-year history of worsening lower pelvic pains exacerbated during standing. Venography demonstrated pelvic collateralization and left CIV occlusion consistent with MTS. The left CIV was stented with complete radiographic resolution.
