Sclerosis of varicose veins is a very minimally invasive technique that consists of puncturing the dilated veins of the lower limbs (varicose veins or variculas if they are small) and introducing an irritant product with high permanence inside the vein (in the form of foam) in order to thrombose the vein and eventually disappear.
The surgery has the advantage of not requiring anesthesia, incisions or closure stitches of any kind so it is easily performed. The incorporation to normal activities is very fast. Sometimes it can leave pigmentation of the clot that forms inside the vein and transmits its color to the skin, so the recommended indication is for varicose veins of small and medium size as well as, in some cases, spider veins.
The risks are minimal and can only cause skin necrosis in those sessions in which there is an excess of sclerosant or very powerful sclerosants are used. In case of hypersensitivity to the product, this technique should be avoided.
In general, the results are very fast or almost immediate, and can even be seen at the moment the technique is performed. On other occasions these same veins, when they fill with blood and coagulate again, suffer a small inflammatory process, a transitory phlebitis that requires a few weeks for its complete resolution.
Often this type of small varicose veins should be studied ultrasonographically to assess whether they come from a problem of larger veins that require other techniques for resolution. Otherwise, and when they exist in a very dispersed and ramified form, the patient must be aware that the number of sessions may be high and the solution may not be definitive, requiring new actions in the future.
