Are there any specific treatments for large varicose veins?
There is a new laser procedure for large or bulging varicose veins, but it entails the insertion of a catheter inside the veins. The energy generated by the laser causes thermal (heat) damage and shrinks the vein. This invasive procedure called Endovenous Closure or Endovenous Laser Ablation (EVLT), may be indicated for patients with severe venous insufficiency and large varicose veins. However, this procedure is not primarily used to treat spider veins; it is also fairly new and not time tested. Microsclerotherapy is still the best choice for the treatment of small and medium size varicose veins and all spider veins.
