RD Global & Invamed recently announced that five-year results of a comparison between cyanoacrylate ablation (CAA) and radiofrequency ablation (RFA), showing that CAA with the company’s VenaBlock venous closure system “seems to be the ideal treatment” for great saphenous vein (GSV) insufficiency, have been published in the Journal of Vascular Surgery (JVS).
According to RD Global & Invamed, VenaBlock represents a new generation in the treatment of varicose veins and has proven to be an effective treatment option with good short-term results, despite it being a relatively new procedure.
The JVS study, authored by Ahmet Daylan (Çiğli Training and Research Hospital, İzmir, Turkey) and Fatih İslamoğlu (Ege Üniversitesi Tıp Fakültesi Kalp ve Damar Cerrahisi Anabilim Dalı, İzmir, Turkey) included patients undergoing either CAA or RFA to treat GSV insufficiency over a five-year period. Preoperative and postoperative CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification, symptoms, recurrence and Doppler ultrasound findings of the patients were compared.
Although closure of all veins was observed on the fifth day for both groups, when the first month closure rates were compared, the CAA treatment method provided a distinctive advantage over the RFA method with a success rate of 98%, RA Global & Invamed report.
