Sclerosing therapy or Sclerotherapy is a medical technique used to reduce spider veins of the lower limbs: that is visible capillaries on the legs, varying in color from bright red to blue / dark green, that although they are connected to the venous system, play no essential functional role .

Sclerosing therapy is done through the injection of a liquid "irritant" (typically polidocanol) that produces coagulation of the treated vessels and their subsequent absorption.

Among the factors that contribute to the development of spider veins, we find:


  • Genetic Inheritance
  • Pregnancy or other events which result of hormonal changes
  • Weight Gain
  • Activities that involve prolonged standing or vice versa excessively sedentary
  • Some medicines


Telangiectasias can assume different aspects: ramifications or individual pots linear, the latter in the cavity of the knee joint. Often occur in conjunction with varicose veins, usually bluish in color, larger, deeper. In case of telangiectasia related to an important venous insufficiency, sclerosing therapy is safe failure, and may need the intervention of the vascular surgeon.

Sclerotherapy occurs without anesthesia, by injection of liquid within the vessels to be treated. The number of injections depends on the extent of "telangiectatic patches" (usually 2-3 injections per patch). When the results are the needle is retracted and a pressure dressing is applied. The duration of the session varies from 15 to 60 minutes. And 'possible to experience burning in the treated areas for a few hours. After each session, spider veins appear less visible. After treatment it is advisable to apply an elastic bandage on the part subjected to sclerotherapy or targeted compression using elastic bandages on the points of injection. Normally, multiple sessions are required to get a good result.

With this procedure are only dealt with telangiectasias open and can not be prevented the formation of new telangiectasias in the future.

An important innovation introduced recently is represented by foam: produced by emulsifying the liquid sclerosant with air. The advantage of the foam compared to the sclerosing liquid is to be more effective at the same concentration, the foam injected into the vein tends to displace the blood inside and only belatedly to mingle with this, thus prolonging the contact time of ' sclerosing agent with the vein wall.

Another important innovation is the laser (laser therapy). For laser therapy are used selective lasers, which have a target well defined depending on the wavelength of the laser beam, identified by means of its color or its content in water. For example in the treatment of red capillaries using a selective laser performs its action when it encounters a target in red (eg, KTP laser 532). In the treatment of the capillaries of the lower limbs sclerotherapy and laser are not necessarily alternative but may be complementary (the combination of the two techniques is said sclero-laser). Sclerotherapy is to be privileged in the presence of large veins and capillaries, the laser is to be preferred in the treatment of red capillaries purposes. The indication laser or sclerotherapy should be evaluated on the basis of the clinical picture and decided by your doctor.

Based on the data available in the literature, about 80% of spider veins and 75% of the final solution are microvarici with sclerotherapy.
