Sclerosis of varicose veins is an invasive technique is very little that is puncture dilated veins of the lower limbs (varicose veins or varicose veins if they are small) and introduction of an irritating product with high stay inside the vein (as foam) in order to thrombose that vein and to finish disappearing.
Surgery has the advantage of not requiring anesthesia, incisions or locking points of any kind so it is easily realizable. The addition to normal activities is very fast. Sometimes you can leave pigmentation clot that forms inside a vein and transmits its color to the skin, so the indication is recommended for varicose veins of small and medium size and, in some cases, spider veins.
The risks are minimal and can only cause skin necrosis in those sessions that an excess of sclerosing produced or used sclerosing powerful. In case of hypersensitivity to the product should be avoided this technique.
Usually the results are very fast and almost immediate, even they are seen in the time of technical. At other times these same veins to re-filled coagulated blood and suffer a small inflammatory process, a transient phlebitis that requires few weeks for full resolution.
Often this type of small varices should be studied by ultrasound to assess whether they come from a problem of major veins that requires other techniques for resolution. If not, and when there are very scattered and branched form, the patient has to be aware that the number of sessions can be high and the solution can not be definitive, requiring new actions in the future.
