Varicose veins of the lower extremities are a common disease with an incidence rate of about 15% in men and 35% in women. It includes the obstruction of venous blood flow in the lower extremities, an increase of pressure in the veins, gradual dilatation of the superficial vein, and the symptoms of thinness of some parts of the the veins. It is mostly engaged in physical labour, especially the standing work people. The disease has a long course and can cause chronic ulcers, thrombotic superficial phlebitis, venous rupture, and other diseases, and the recurrence rate is relatively high. It is related to age, gender, weakness of the venous wall, valve defect, and continuous increase of venous pressure.

With the advent of LASER treatment EVLA / EVLT the treatment is now done as a day care procedure. There is no need for surgery, cuts, stitches or scars.
