Activity Description

May-Thurner syndrome is characterized by venous insufficiency, obstruction, or thrombosis from impaired venous return secondary to venous compression. The most common anatomical variant in patients with May-Thurner syndrome is compression of the left common iliac vein against the spine by the overlying right common iliac artery. Venous compression usually occurs between the aortic origination of the common iliac artery and the iliofemoral junction. The pulsations of the overriding artery compress the vein against the lower lumbar vertebrae, injure the venous endothelium, and promote the formation of endovenous fibrous bands or spurs. May-Thurner syndrome most commonly affects the left iliofemoral vein; alternate anatomical variations have been reported.

May-Thurner syndrome is an underdiagnosed cause of iliofemoral deep vein thrombosis, accounting for 2% to 5% of all deep vein thromboses. Iliofemoral venous thromboses can be extensive and, without proper diagnosis and treatment, have significant morbidity. Mortality from May-Thurner syndrome is usually due to concomitant pulmonary embolism. This activity reviews the etiology, epidemiology, pathophysiology, clinical presentation, diagnostic evaluation, and treatment of May-Thurner syndrome and highlights the role of the interprofessional team in improving outcomes for patients symptomatic of this vascular anatomical variant.
