Foam Sclerotherapy for Varicose Veins in the Legs


There has been an increasing interest in the use of foam sclerotherapy in the treatment of varicose veins in the legs. Of course, VNUS Closure is most appropriate for patients with venous reflux in the saphenous vein, so foam sclerotherapy is reserved for surface leg veins that are separate from the saphenous vein.

Foam sclerotherapy refers to the mixing of a sclerotherapy medication with room air (or carbon dioxide) to generate a foamed agent.  It is then injected with a very small needle into varicose veins, leading eventually to vein shrinkage and disappearance. Another treatment that achieves the same result is microphlebectomy.
Foam sclerotherapy has been used in Europe for many years with variable results. As with all medical procedures, the knowledge of when to use each technique is critical, as foam sclerotherapy is not advisable in all cases. There are limited situations where this is a very useful technique.
Again, with all procedures, there are risks and benefits. Foam sclerotherapy has a risk profile that is unique and needs to be discussed with your physician before the decision is made to pursue it.  Microphlebectomy, using very tiny nicks in the skin to remove varicose veins, is very effective and leads to a quicker resolution of the problem leg veins.
