Sclerosis with foam is a technique of elimination of varices that consists of the introduction of a sclerosing product , usually micronized polidocanol, mixed with a gas that can be the CO2 or ambient air, producing a chemical reaction that generates foam. This foam is introduced into a varnish to occlude it, ie to make it dry.
How does this technique work?
The introduction of the foam produces a vasospasm that displaces the blood and allows selective treatment of the inner wall of the varicose vein , transforming it in a few months into a cicatricial cord that does not circulate blood.
Initially it was used for the treatment of small varicose veins and spider veins, as well as in cosmetic treatments and residual varices after surgery. At present, due to the use of echo-Doppler, this technique can be used in all types of varicose veins , treatment of venous ulcers and angiodysplasias and congenital vascular diseases.
Advantages and disadvantages of this technique
The main advantage of this treatment is that it is an outpatient technique. It is also important to note that it can be done at the same doctor's office and does not require anesthesia.
Among its possible disadvantages are the possibility of varicophlebitis, pigmentation of the skin and, if large varices are treated, relapses.
How is the postoperative?
After treatment, the patient can make a completely normal life from the first moment; Sport included (bicycle, gym or running, for example) using a mean compression for a few days. It is not necessary to leave the work.
In small varices the results are long lasting. However, in truncal varices, early failures can occur, failed occlusions. In the long term, in addition, the recanalization of the varices can be given, that is to say, a new appearance.
Risks of the intervention
This technique should not be used in patients with chronic ischemia of the lower limbs, whether moderate or even more important. A possible complication of this technique is the reaction to the sclerosant, which can occur in one of every 3,000 treated cases.
