Endovenous laser and Endovenous Radiofrequency Ablation are used to treat large "trunk" varicose veins which underlie the grape like veins that can appear on the lower legs. During this procedure, a thin laser or radiofrequency fibre is introduced into the vein through a needle, and is passed along the full length of the vein under ultrasound guidance. Under local anaesthetic, the fibre then seals the vein using a heating process.
Studies have shown this procedure to be at least as effective as surgery for large varicose veins, with only a fraction of the pain, only one scar 3-4mm in length and minimal down time. There is no need for general anaesthesia or hospital admission.
It is usually necessary to complete the varicose vein treatment with ultrasound guided sclerotherapy several weeks after the laser treatment.
