What is CVI? Chronic venous insufficiency (CVI) is a condition that occurs when the walls and or valves of the leg veins do not work correctly. Veins function to return blood to the heart. For the blood in your legs to return to nature, it needs to flow upward, so the leg veins' one-way "valves" stop the blood from flowing back down. When these valves become damaged, it causes the blood to leak back down and accumulate in the leg veins. Over time, CVI can cause varicose veins, spider veins and swelling of the legs, itching and the development of ulcers near the ankles.
