Lumbar radiculopathy after left common iliac vein stent placement.

Left common iliac vein stent placement for symptomatic compression by the right common iliac artery, an entity known as May-Thurner syndrome, is a procedure performed with increasing frequency and good clinical outcomes. In this institutional review board-approved retrospective electronic medical record review, we describe three cases of left L5 lumbar radiculopathy immediately after left common iliac vein stent placement performed elsewhere. Additionally, we describe surgical and endovascular approaches for correction, the utility of multimodality diagnostic testing, and endovascular technique to consider in avoiding this entity. All described patients had postoperative relief of their longstanding symptoms.
