Mechanochemical ablation of varicose veins with N-Butyl Cyanoacrylate: Six-month follow-up

Abstract

Aim: The endovenous treatment with n-butyl cyanoacrylate (NBCA) is a new nontumescent ablation technique for symptomatic saphenous vein reflux. The aim of the present study is to present six-month follow-up results of NBCA (VenaBlock) mechanochemical ablation technique. Material and Methods: Endovenous ablation was performed on 29 saphenous veinsof 23 patients between January 2017 and October 2018 in our university hospital. All patients with six-month follow-up results were included. Patients’ pre- and postoperative data were recorded. Results: This procedure was performed on eight small saphenous veins in seven patients and 21 great saphenous veins in 16 patients. The mean saphenous vein diameters for great and small saphenous vein were 7.1 and 3.8, respectively. The mean lengths for great and small saphenous vein were 45 cm and 19 cm, respectively. Closure rates were 100% at one week, 100% at one month, 100% at three months and 96% at six months. CEAP score was significantly improved (p<0.001). There was one deep venous thrombosis patient as a complication. Conclusion: The NBCA-based vein ablation technique is a fast end affective treatment method with no tumescent anesthesia requirement and high patient toleration. Further large-scale studies with long-term follow-up results are required.
