[Successful endovascular treatment of proximal deep vein thrombosis following May-Thurner syndrome].

We present two clinical cases of successful endovascular treatment of proximal deep vein thrombosis following May-Thurner syndrome. In the first case, 2-day regional catheter thrombolysis, percutaneous mechanical thrombectomy and venous stenting were required to restore hemodynamics in the left lower limb. In the second case, regional catheter thrombolysis continued for 3 days with subsequent thrombotic mass lysis. However, iliac vein was severely narrowed that required venous stenting. Long-term results were favorable in both cases. Venous outflow has become almost normal after endovascular treatment. The patients' ability to work has been restored.
