A 61-year-old woman with May-Thurner anatomy status post recent hysterectomy was found to have two iliac vein aneurysms on postoperative magnetic resonance imaging. Transfemoral venography showed the venous aneurysms received retrograde flow from the left internal iliac vein and the left common iliac vein (CIV) was compressed by the right common iliac artery. Both aneurysms were coil embolized and a left CIV stent was placed. Our initial experience suggests that iliac vein aneurysms may be caused by CIV compression and an endovascular approach is safe and effective to treat both lesions.
