May-Thurner syndrome: modern methods of diagnosis and treatment
May-Turner syndrome is a condition where the left common iliac vein is compressed between the lumbar spine and the overlying right common iliac artery. Left iliac vein compression is common (up to 24%) in the general population, but clinical manifestations occur in a few patients. This syndrome should be considered in case of unexplained edema of the left lower extremity since routine duplex ultrasound does not possess optimal sensitivity and specificity in the study of the iliac veins and the inferior vena cava. Intravascular ultrasound is the most accurate diagnostic method. However, the advent of computed tomography angiography and magnetic resonance angiography providing high-quality images of the vasculature have become a promising alternative to invasive intravascular ultrasound. Treatment for May-Turner syndrome usually involves stenting of the left common iliac vein along with medical therapy, including antithrombotic (anticoagulant and antiplatelet) therapy combined with phlebotonics. Our review reports modern methods of diagnosis and treatment of May-Turner syndrome.
