May‐Thurner syndrome: A cause of unexplained unilateral leg edema

Abstract

Abstract Physicians should be familiar with May‐Thurner syndrome, characterized by the compression of the left common iliac vein by the right common iliac artery and the vertebral body, resulting in pain and swelling of the left lower extremity and DVT. A 64‐year‐old woman presented with unexplained edema in the left lower extremity. Computed tomography with contrast enhancement revealed that the left common iliac vein was compressed and narrowed by the right common iliac artery and the vertebral body, leading to the diagnosis of May‐Thurner syndrome.
