RESUMO
OBJECTIVE: To evaluate the 6 months efficacy and safety of cyanoacrylate closure for the treatment of incompetent great saphenous veins (GSVs) in comparison with radiofrequency ablation (RFA). METHODS: In this multicenter, retrospective, clinical trial, 398 symptomatic subjects with incompetent GSVs were assigned to either cyanoacrylate closure or RFA. The primary endpoint, complete closure of the target GSV, was determined using duplex ultrasound examination starting from one-, three-, and six-month visits. RESULTS: All patients were followed for 6 months and there was no difference between the groups in terms of mean follow-up time. Hospital stay and return to work/activity were shorter in the cyanoacrylate ablation (CAA) group, and these differences between the groups were statistically significant. Ecchymosis was observed higher in the RFA group and was statistically significant. CONCLUSIONS: In this study, in which we examined the CAA and RFA methods, we found that both methods were effective and reliable; however, we found that patients in the CAA group had a more comfortable postoperative period and returned to work earlier.
