Re-intervention for occluded iliac vein stents.

Iliac vein stenting has become more frequent with improved diagnostic capabilities of intra-vascular ultrasound (IVUS) for recognizing May-Thurner syndrome, chronic venous insufficiency (CVI) and thrombus. In this manuscript, we discuss the reasons for initial stenting, with long-term outcomes and some of the associated pitfalls. The best techniques for re-intervention when iliac stents become occluded will also be discussed.
