Venous Stent Patency

Iliac vein compression syndrome (May-Thurner syndrome) is effectively relieved by endovascular placement of a stent in the left common iliac vein, with greater than 90% stent patency after 1 year. MR imaging is a safe and effective method of evaluating for stent patency, whether as part of routine surveillance, in patients whose leg swelling persists after stent placement, or in the setting of acute left leg edema after stent placement.
