BACKGROUND: The treatment of chronic venous disease, has largely shifted from high ligation and stripping to endovenous thermal ablation (EVTA) techniques, because of its comparable efficacy and lack of invasiveness. This clinical trial aimed to compare the efficacy of two thermal ablation techniques, endovenous laser ablation (EVLA) 1470-nm with Tulip-TipTM fiber and radiofrequency ablation (RFA) ClosureFastTM using a non-inferiority design for occlusion rate (primary outcome).
METHODS: A prospective multicenter randomized clinical trial randomized 280 patients for the treatment of great saphenous vein (GSV) reflux. Primary outcome was the GSV occlusion rate, secondary outcome factors were the possible side-effects of the treatment such as pain, ecchymosis, quality of Life (CIVIQ-20), revised Venous Clinical Severity Score (r-VCSS). One-year follow-up period.
RESULTS: The total occlusion rates at one year follow-up were 96.4% and 94.5% in the EVLA and RFA groups respectively (P=0.15). Regarding secondary outcomes, such as postoperative CIVIQ-20, r-VCSS, analgesia, absenteeism, there was no significant difference between both treatment groups.
CONCLUSIONS: RFA and EVLA, using a 1470 nm laser with Tulip-TipTM fiber, of the GSV results in equal occlusion rates at one year, with comparable postoperative pain and improved quality of life.
