Chronic Venous Insufficiency (CVI) is a progressive medical condition that worsens over time and affects the veins and vessels in the leg that carry oxygen-poor blood back toward the heart. Varicose veins, which are enlarged veins in the leg that appear like twisted, bulging cords, can progress to CVI if left untreated.

There are a number of factors that contribute to varicose veins and CVI, including pregnancy and heredity. As varicose veins progress to become CVI, other painful symptoms like leg swelling, skin damage and ulcers may occur.
