Varicose vein removalVaricose veins are usually harmless and often cosmetically disturbing. However, in some cases, varicose veins provide physical symptoms such as pain, heaviness, itching, tenderness or tingling in the legs. Untreated varicose veins can sometimes lead to eczema, and leg ulcers.

Varices are caused by impaired function of the valves. Inside the veins there are valves that act as check vales which is to carry blood back to the lungs. Therefore, reverse flow in these veins increases the pressure , leading them to being stretched and eventually they begin to bulge out.

Varicose veins are classified on a six-point scale

To determine the severity of the varicose veins are uses in healthcare an international six-point scale called CEAP classification of varicose veins. Patients are divided into following clinical classification as shown below:

  1. C0 No visible signs of varicose veins or only superficially visible vessels shown.
  2. C1 One or a few millimeters of large superficial veins/spider veins that are visible under the skin. These are not counted as varicose veins.
  3. C2 Visible varicose veins are shown. The blood vessels are wider than 4 mm.
  4. C3 Visible varicose veins are shown and swelling/edema in the leg.
  5. Varicose veins are classified on a six-point scaleC4 Visible varicose veins are shown and skin surface exhibits eczema, pigmentation or whitish areas.
  6. C5 Visible varicose veins are shown and skin surface showss healed scars from ulcers.
  7. C6 Visible varicose veins are shown with active ulcers in the overlying skin.

In addition to the CEAP scale, varices are also divided as in symptomatic (s), which means that they provide physical symptoms and asymptomatic (a), if they are only cosmetically disturbing. For example, a patient may be C2 – varicose vein classication C2 with physicial complaints (s).
