200 patients with insufficient great saphenous veins will be randomized to either
radiofrequency ablation or high ligation/stripping (open surgery). They will be examined
according to standardized examination protocol Venous Clinical Severity Score (VCSS), with

They are to fill questionnaires EuroQol 5 Dimensions (EQ-5D) and disease specific Aberdeen
