Can EVLA be used to treat perforators? Yes. EVLA is the first line treatment for perforators. If EVLA is not possible, perforators can be treated using foam sclerotherapy, or, occasionally, open ligation may be required. At Veincentre, we treat perforator veins at the same time as the other veins being treated with EVLA, so there is no additional charge for these. Our EVLA prices are fixed per leg, regardless of the total number of veins or the types of veins needing EVLA.
