May-Thurner syndrome successfully managed with an endovascular stent: A case report

Abstract

May-Thurner Syndrome (MTS) or iliac vein compression syndrome is caused by compression of the left common iliac vein by the right common iliac artery. The incidence rate of MTS is unknown. In an autopsy study in the early twentieth century, the incidence ranges from 22 to 32%. MTS-related deep venous thrombosis accounts for only 2%-3% of all lower limb DVTs. The patient may present with leg swelling, varicosities, deep venous thrombosis, chronic venous stasis ulcers, or more serious complications, such as pulmonary embolism. Iliac vein compression can be assessed with Computed Tomography (CT) and iliac venography. The goal of treatment is to reduce symptoms and the risk of complications. Stent placement is an alternative method to a direct surgical approach. We present 2 cases of MTS that were treated with stent placement.
