OBJECTIVE: The aim of this study is to compare the clinical efficacy and safety of two laser wavelengths and fiber types in endovenous laser ablation (EVLA) of saphenous varicose veins of the lower limb. DESIGN: Multi-center prospective randomized non-blind clinical trial. @entity1 AND METHODS: From January 2007 to December 2011, 113 @entity1 (113 limbs) with primary varicose veins were randomized into two groups. They were treated with radial 2ring fiber and 1470 nm laser in Group I (57 limbs) and bare- @entity5936 fiber and 980 nm laser in Group E (56 limbs) in order to ablate the saphenous vein. @entity2994 rates at 12 weeks and @entity158 in treated region were recorded as primary endpoint. Visual analogue scale (VAS) for assessment of @entity158 , rates of @entity2981 , complications and equipment failure were recorded as secondary endpoint of safety. RESULTS: Occlusion rates at 12 weeks were 100% in both groups. Rates of @entity158 (0% vs. 25.0%) and @entity2981 (7.0% vs. 57.1%) were significantly lower in Group I (p <0.0001). VAS of @entity158 was significantly lower on postoperative day 1, day 5 and 2nd week in Group I. CONCLUSION: Treatment of saphenous varicose veins by EVLA using a 1470 nm laser and a radial 2ring fiber resulted in comparable occlusion rates at 12 weeks and less @entity282 and @entity2981 than EVLA with a 980 nm laser and a bare- @entity5936 fiber.
