Cyanoacrylate Closure of Small Saphenous Vein Insufficiency

BACKGROUND: As minimally invasive techniques were issued, endovenous thermal ablations have emerged. However, the thermal-associated complication has been reported in the treatment of small saphenous vein (SSV) insufficiency, such as sural nerve injury. Recently introduced cyanoacrylate closure (CAC) is a nonthermal modality, so this thermal-associated complication can be avoided. OBJECTIVE: This retrospective study analyzed the feasibility, safety, and 2-year results of CAC for treating SSV insufficiency, particularly the incidence of sural nerve injury. MATERIALS AND METHODS: One hundred sixty-three SSV insufficiencies in 128 patients were treated with CAC were reviewed. Pain, venous severity, and quality of life (QoL) scores were evaluated. Postoperative duplex scanning also evaluated anatomical and clinical success rates. RESULTS: The mean patient age was 56.8 years. The initial technical success rate was 100%. The occlusion rate after 2 years was 96.3%. Pain, venous severity, and QoL scores were improved significantly from 2.4 to 0.0, 4.39 to 0.47, and 11.95 to 2.69, respectively, before and 2 years after CAC. No major complications were observed, such as sural nerve injury. CONCLUSION: Cyanoacrylate closure for the ablation of SSV insufficiency could be a great alternative to endothermal ablation with an excellent success rate and shorter procedure time.
