Veins become congested with blood resulting in spider veins or varicose veins. Spider veins are small red, blue or purple veins on the surface of the skin. Varicose veins are larger, bulging, and tortuous veins that are located somewhat deeper than the spider veins What causes varicose vein? Hereditary is the number one contributing factor. Hormonal factors include pregnancy. Other predisposing factors are standing occupations, obesity and heavy weight lifting. Evaluation of varicose vein Accurate identification of the origin of back flow (reflux) is a prerequisite for the planning of any intervention. Varicose vein is diagnosed primarily by physical examination. The usual pattern of distribution are the 1) great saphenous vein 2) small saphenous vein 3) incompetent perforating veins. Origin of reflux often can be deduced by physical examination.  Sometimes Duplex scan is required to pinpoint the site of reflux.  "Duplex scan" detects leaking valves, direction of blood flow and evidence of previous blood clots. It also provides a map of the affected veins and their connection. ► Back to top
