Varicose vein surgery is among the most commonly performed surgical interventions. The standard treatment “high ligation and stripping” has in many countries been replaced by endovenous techniques. However there are many different techniques available. All have a different way of action and sometimes need different skills. The purpose of this review article is to give an update in those different endovenous ablation techniques. We describe the indications, technique, mechanisms of action and results. We conclude that all different techniques can be used safely and are effective. Even on long term there seems to be no difference in outcome, even compared to high ligation and stripping.
