Varicose vein (v.v) shows popular prevalence and needs for treatment is increasing. Endovenous laser therapy (EVLT) and radio-frequency ablation (EVRFA) is now recognized as the standard treatment modality for v.v because of various merits. After endovenous non-invasive treatment, remnant varicosity can be the problem. So simultaneous or later foam sclerotherapy or ambulatory microphlebectomy is now added in many EVLT/EVRFA patients. The effectiveness and necessity of additional treatment is debatable in the point of timing and choice of methods. However, it may be the trend to do the additional treatment for the EVLT/EVRFA patients of varicose vein. It is new and innovated treatment modality to do the foam sclerotherapy through endovenous approach using fluoroscopy. It shows more cure rate and less complication rate. Although it may be difficult to apply this treatment method in the entire institute to have the therapeutic clinics of varicose vein, it can open the field of treatment modality of varicose vein wider. And additional treatment for the EVLT/EVRFA is increasing and should be considered. (Korean J Phlebology 2014;13:10-14)
