Early Results of the Sandwich Technique Using Cyanoacrylate Glue and Polidocanol Foam Sclerotherapy for the Treatment of Varicose Veins

Background. This is a retrospective analysis of the results of treatment for varicose veins using the sandwich technique with cyanoacrylate glue and foam sclerotherapy. This novel method al-lows for substantial reduction of amount of glue needed for the vein closure, and minimizes the risk of granuloma formation and allergic reaction related to the epifascial administration of cy-anoacrylate. Methods: This technique was used in 60 patients, 77 intrafascial veins were managed. Vein closures were performed with Venex cyanoacrylate glue and 1-3% polidocanol foam. All proce-dures were done under ultrasonographic control, though direct percutaneous punctures of target veins. Follow-up were scheduled 1-3 week after the procedure. If revealed, unclosed segments of the target veins were obliterated at these follow-up visits, with glue and/or sclerotherapy. Results. There were no serious adverse events intra- or postprocedurally. The technical success rate was 100%. The primary success rate at 1-3 week follow-up was 84.4%. The primary assisted success rate, after additional closures, was 100%. Conclusions. We demonstrated that the treatment for varicose veins, using sandwich tech-nique, which combines cyanoacrylate glue and foam sclerotherapy, can be safe and efficient.
