Symptomatic compression of right iliac vein after right iliac artery stent placement

Abstract

Right lower extremity edema can be a presenting symptom of iliocaval compression syndrome, even in the absence of deep vein thrombosis. It has been reported in idiopathic and rarely, iatrogenic, cases secondary to variant anatomy, arterial stents, and bony hardware. Classically seen in the more confined left common iliac vein as May-Thurner syndrome, it is rare on the right side. We report an unusual case of acute right common iliac vein compression after right iliac stent placement leading to symptomatic right leg edema. Venous stenting resulted in resolution of symptoms at the 6-month follow-up.
