The article describes a clinical case of treatment of complications of the May-Thurner syndrome. Asymmetry of blood flow in the iliac veins and signs of their narrowing were observed. Phlebography showed special characteristics of pelvic vessels, trajectory of the surgery was planned. Stenting of the left iliac vein is considered the optimal treatment for such patients if the pressure in it is above 5 mmHg compared to the inferior vena cava. Specialized venous self-expanding stents are an efficient choice for stenting. Access can be performed through the popliteal vein on the unilateral side and/or the femoral or humeral artery, jugular or subclavian access can be used depending on the patient's anatomy and the size of the delivery device. The female patient underwent coil embolization of varicocele of the lower pelvic veins. At repeat examination after 3 months, pelvic pain was minimal, no pain during sex, no varicocele in the groin and lower extremities. Contrast-enhanced spiral computed tomography with 3D reconstruction of the pelvic veins didn't show any signs of pelvic congestion syndrome. © 2019 Andrologia i Genital'naa Hirurgia.
