May Thurner syndrome (MTS) is an anatomically variable condition of venous outflow obstruction caused by extrinsic obstruction [1], resulting in an acquired stenosis commonly of the left common iliac vein secondary to compression by the overlying right common iliac artery [2]. Venous outflow obstruction in young adults was not well understood until 1957 when Dr. Robert May and Dr. Joseph Thurner concluded in their study of 430 cadavers that thrombosis of the pelvic veins occurs approximately eight times more frequently on the left side than on the right side of the pelvis. They attributed this to spur-like formations in the left common iliac vein and described three types of these formations. The first protrudes into the lumen like a pier or pillar, the second divides the lumen completely, and the third obstructs it almost entirely. Based on their histologic data, they reported that those formations are not of a congenital origin but develop during the patient’s lifetime [3]. The exact prevalence of MTS is not well known. Many studies estimated an asymptomatic anatomical variant in the general population to be 22-32% [3-5].
