Iliofemoral deep venous thrombosis (DVT) is five times more likely to occur in the left leg when compared with the right leg. May and Thurner provided an explanation for this phenomenon by discovering an anatomical variation of left common iliac vein in 1957. This syndrome is caused by vascular thickening of the left common iliac vein at the crossing point and compression between the fifth lumbar vertebrae and overlying right common iliac artery. Cases with Iliofemoral extension of the thrombus including iliofemoral obstruction create a major challenge. Although in MTS, anticoagulant therapy alone does not prevent long-term complications. To avoid re-thrombosis, venous outflow should be re-established, ensuring that there is no residual stenosis in the left iliac vein. Here in, we present a case of our experience about treatment for DVT due to MTS with endovascular method and evaluate our result of this treatment.
