Endovenous treatment of lower-limb varices by laser and radiofrequency

Endovenous treatment of varicose veins is an old technique, but new procedures using both radiofrequency and laser have markedly revived interest in it. In effect, the thermal energy these procedures generate and deliver to the venous wall results in vein wall fibrotic retraction and its subsequent occlusion. Details are given on the material and techniques used, including the difficulties, incidents, and accidents that can be encountered during the procedure. The indications and contraindications concerning endovenous treatment of varicose veins are still debatable. Assessment of results remains difficult, particularly in laser procedures, since the material and technique used is variable and the techniques nonstandardized. Besides long-term results are not yet available.
