Eight year results of patients with varicose vein underwent endovenous occlusion using n-butyl cyanoacrylate

ObjectiveTo present the 8-year results of 180 patients on whom we performed endovenous occlusion using N-butyl cyanoacrylate in 2014.MethodsWe have previously published the 30-month results for 168 patients available for follow-up. Thirteen more patients were lost to follow-up in the 8-year research period. The remaining 155 patients underwent clinical examinations and their Venous Clinical Severity Score (VCSS) values were recorded. Doppler ultrasonography was performed, and whether the saphenous vein was occluded, or whether partial or complete recanalization were present was evaluated.ResultsThe mean age of the 155 patients we were able to follow-up was 47.4 ± 11.8 years. Sixty-eight of the patients were men, and 87 were women. Mean VCSS scores were 10.2 before the procedure, 2.7 at 30 months, and 2.6 ± 0.7 at 8 years. Complete recanalization was observed in seven patients over the 8 years, and partial recanalization in six. Occlusion rates were 94.1% at 30 months and 91.7% at 8 years.ConclusionThe long-term results of the use of N-butyl cyanoacrylate in the treatment of patients with varices are highly satisfying in terms of a high ablation rate.
