UGFS is a new method of treating veins for patients where usually the veins are not palpable. Very little local anaesthesia is given at the site and then needle is inserted in the affected vein under ultrasound imaging and then the foammed sclerosant is instilled through that needle. Ultrasound is used to make sure that the foam enters all the varicose veins but does not enter the normal veins .The foam works by forcing the blood out the varicose veins and then by making the walls of the vein sticky so that the vein closes off. Over a period of a few weeks and months the treated vein shrivel up and disappear.
Ultrasound guided foam sclerotherapy also has the added benefit of being a fraction of the cost of other treatment options.
