Successful endovascular exclusion of an isolated iliac artery aneurysm causing “May–Thurner effect”

Abstract

May–Thurner syndrome is a well-recognized entity, often described as the right common iliac artery (CIA) compression of the left common iliac vein (CIV), however, other configurations are possible. It is often associated with lower limb edema, recurrent varicose veins, and unprovoked deep femoral vein thrombosis. Herein, we present an unusual case where aneurysmal dilation of the right CIA resulted in the compression of the bilateral CIVs resulting in a bilateral May–Thurner effect. The management of this patient and the pathophysiology of May–Thurner syndrome are also discussed.
