Overview
May-Thurner syndrome is deep vein thrombosis of the iliofemoral vein due to compression of the left common iliac vein by overlying right common iliac artery.[1][2] In contrast to the right common iliac vein, which ascends almost vertically to the inferior vena cava, the left common iliac vein takes a more transverse course. Along this course, it underlies the right common iliac artery, which may compress it against the lumbar spine.
