Video Overview

Are all varicose veins visible? Varicose veins are a manifestation of chronic venous insufficiency. This refers to a problem where the valves in our veins in our legs do not work. Veins are built to bring blood out of the legs. They do this via one way valves that promote blood flow upward towards the heart. When those valves do not work, blood then moves backwards through the veins and leaks out into some branches. These branches dilate, become bulgy and are called varicose veins. Chronic venous insufficiency, however, may not be as apparent. Patients typically develop swelling, tiredness, heaviness and fatigue in their legs prior to developing any visible varicose veins. Once visible varicose veins are apparent, chronic venous insufficiency has progressed and can be very severe. Complications from varicose veins that are visible may include clotting, bleeding and pain.
