May-Thurner syndrome
Pronunciation: MAY-thur-ner
Anatomical compression of left iliac vein by right iliac artery, predisposing to venous thrombosis.
Full Definition
May-Thurner syndrome, also known as iliac vein compression syndrome, occurs when the right common iliac artery compresses the left common iliac vein against the lumbar spine. This anatomical variant can cause chronic venous outflow obstruction, leading to left leg swelling, pain, and increased risk of deep vein thrombosis. The condition predominantly affects young to middle-aged women and may present with isolated left-sided DVT. Diagnosis is confirmed by cross-sectional imaging showing venous compression, and treatment may involve venoplasty and stenting.
Usage
Usage note: Always hyphenate when using as an adjective; May-Thurner syndrome is preferred over eponymous alternatives.
