Case ReportsMay-Thurner syndrome resulting in acute iliofemoral deep vein thrombosis during the second trimester of pregnancy.
Described is a 27-year-old pregnant woman with May-Thurner syndrome who experienced extensive pelvic and lower extremity thromboses during the antepartum period. The patient was referred for a symptomatic deep venous thrombosis at 23 weeks of gestation. Ultrasonography demonstrated a massive thrombus in the left iliofemoral vein. ⋯ Postpartum computed tomography (CT) demonstrated compression of the left common iliac vein by the right common iliac artery and lumbar vertebra. CT venogram demonstrated poor flow through the common iliac vein and well-developed collateral vessels. Critical stenosis at the origin of the left common iliac vein was consistent with a diagnosis of May-Thurner syndrome.
