Foam sclerotherapy closes off the treated veins by injecting a foam which is made up of a mixture of either air or carbon dioxide and the sclerosing agent Fibrovein. This causes a controlled inflammation in the vein wall. Constant pressure applied by a compression bandage and stocking then collapses the vein.
Which varicose veins are suitable?
Varicose veins arising from the groin, the long saphenous system, and behind the knee, short saphenous veins as well as perforator veins are suitable for treatment with foam sclerotherapy.
How is the procedure performed?
This procedure is performed under a local anaesthetic. A plastic cannula is inserted into the vein to be treated under ultrasound control. The foam is mixed using a chemical called Fibrovein and carbon dioxide or air. This is injected into the vein and then a compression bandage is applied. This needs to be kept in place with a compression stocking which is worn for a week afterwards.
What are the potential complications?
The main potential complication appears to be discolouration over the treated vein. There have also been reports of transient loss of sight and rarely of transient neurological events similar to mini-strokes.
What are the alternative treatments?
These include no treatment, compression stockings, and radio-frequency ablation. As part of your consultation these alternatives will be discussed, allowing you to choose the most appropriate treatment.
