• Compression of the Iliac vein by the Iliac artery (May-Thurner Syndrome/Iliac Vein Compression Syndrome) inhibits venous flow and is the most probable cause of Iliofemoral Deep Venous Thrombosis
• Deep Venous Thrombosis (DVT) can cause leg pain, swelling and redness of the skin
• Of patients with class 5 and 6 chronic venous insufficiency, 37% of patients have at least 50% narrowing at some point in the iliac or caval venous systems.
• A dedicated venous stent will counteract compressive forces in the iliac vein to allow for adequate blood flow and improve the quality of life for May Thurner patients.
