May-Thurner syndrome: management by endovascular surgical techniques.

May-Thurner syndrome is a condition in which there is impaired venous return due to compression of the left common iliac vein by the overlying right common iliac artery. The impedance of flow occurs both by the compressive force of the artery against the vein and by resultant intraluminal web formation inside the vein. Because of the mechanical nature of the obstruction, conservative management of these patients has resulted in poor outcomes. Typically, operative therapy is recommended and perused via various approaches. We have recently treated a 15-year-old patient with this disorder utilizing endovascular surgical techniques with an excellent outcome. A 1-year follow-up is presented.
