Comparative analysis of five-year outcomes of lower extremity varicose vein therapy using monopolar and segmental radiofrequency ablation

BACKGROUND: To compare efficacy and safety of segmental and monopolar radiofrequency ablation in the management of lower extremity varicose veins. METHODS: A total of 193 patients were treated with segmental RF ablation (Venefit; N.=97) or monopolar RF ablation (EVRF; N.=96) for lower extremity varicose veins from 2010 to 2012. A single extremity of each patient with isolated GSV or SSV insufficiency was enrolled. The differences between the two groups in demographic parameters, disease severity, treated veins, peri- and postoperative complications, and treatment efficacy indicators (VCSS) were evaluated. RESULTS: Based on Kaplan-Meier's analysis, the occlusion rate after 5 years was 87.6% in Venefit group and 87.8% in EVFR group (P>0.05). Varicose vein recurrence rates were 10.3% and 12.9% in the Venefit and EVFR groups, respectively (P>0.05). The VCSS reduction was comparable between the two groups (P<0.05). CONCLUSIONS: Venefit and EVRF systems can be considered equivalent in terms of efficacy and safety in the management of lower extremity varicose veins.
