Abstract

Objective: Our main objective was to evaluate the short- and long-term efficacy of Celon radiofrequency-induced thermal therapy for endovenous treatment of incompetent great saphenous vein. The secondary objectives were to report on possible short-term side effects and complications.

Methods: This was a retrospective study of 112 consecutive patients included between 2013 and June 2015. These patients were treated (146 great saphenous vein, C2-C6) either at the hemodynamic room using local anesthesia or at the operating theater under general anesthesia with or without phlebectomy. All patients received radiofrequency-induced thermal therapy at 18 W power, 1 s/cm pullback rate and 5-7 pullbacks per segment of 10 cm (i.e. maximum 10 pullbacks). A clinical follow-up via ultrasound monitoring was done at 1 week, 1 month, 6 months, 1 year, 2 years and 3 years.

Results: The 3-year survival occlusion rate was 96.71% and 98% for overall and radiofrequency-induced thermal therapy patients, respectively. No major side effects were observed. A case of endovenous heat-induced thrombosis was reported. Slight neurological disorders were reported (0.88%).

Conclusion: Our unit's endovenous Celon radiofrequency-induced thermal therapy of incompetent great saphenous vein was efficient, well tolerated, without major side effects. Moreover, in order to reduce possible neurological disorders, we advise multiple pullbacks at 1 s/cm and using tumescence anesthesia.

Keywords: Thermal endovenous vein ablation; saphenous vein; varicose vein.
