What is May-Thurner Syndrome?

May-Thurner Syndrome is characterized by the compression of the left common iliac vein, typically by the overlying right common iliac artery. This compression can lead to venous stasis, resulting in a higher incidence of deep vein thrombosis (DVT) in the left leg. The anatomical positioning creates a situation where the left common iliac vein is subject to external pressure, making it less favorable for blood flow and increasing the risk of clot formation.

Understanding this condition emphasizes the significance of anatomical relationships in vascular pathology. In May-Thurner Syndrome, the left common iliac vein's vulnerability to compression can facilitate the development of deep vein thrombosis, particularly on the left side, which is a critical clinical consideration for diagnosis and treatment.
