Abstract

<p>This article provides the early results of cyanoacrylate closure (CAC) for the treatment of incompetent great saphenous veins, which eliminates the need for tumescent anesthesia and thermal energy. This study investigated 32 consecutive patients (18 women; mean age, 64.2±1.6 years) with varicose veins between September 2020 and December 2021. We performed CAC therapy for truncal veins without stab avulsion phlebectomy, followed by sclerotherapy for incompetent tributary varicosities and the below-knee great saphenous vein (BKGSV) after 2–4 weeks. Sclerotherapy was performed before CAC therapy in 24 cases (75.0%). Residual reflux in the BKGSV after endovenous therapy persisted in 21 cases (65.6%), over a mean follow-up period of 8.6±0.9 months (range, 0–15 months). Hypersensitive reactions (HSR) were observed in four cases (12.5%). All cases of HSR occurred in patients whom in the great saphenous vein was at a depth <3 mm from the skin. We obtained good early results in terms of closure rates of incompetent great saphenous veins using CAC. These results show that CAC therapy was favorable, albeit with a short follow-up period without severe complications.</p>
