Objective: Radiofrequency thermal ablation is an effective and safe treatment for varicose veins. Existing radiofrequency thermal ablation devices in Korea detect the temperature of the catheter to adjust the radiofrequency output. In contrast, VENISTARⓡ, a new radiofrequency thermal ablation device, detects the resistance of the vein wall during ablation to adjust the radiofrequency output. Herein, the safety and effects of VENISTARⓡ were assessed.
Methods: A total of 60 patients with varicose veins who were treated using VENISTARⓡ from January 2021 to September 2022 at our institution were retrospectively analyzed. In this study, 60 patients (41 males and 19 females) were treated with VENISTARⓡ.
Results: The mean age was 46.2±11.7 years for males and 52.7±14.2 years for females. CEAP classification was as follows: 28, 26, 4, and 2 patients had C2, C3, C4a, and C4c, respectively. A total of 89 truncal veins were treated, including 79 cases of the great saphenous vein and 10 cases of the small saphenous vein. The mean follow-up period was 190±130 days, and the success rate of treatment with VENISTARⓡ was 97.7%. Complications included 20 cases of bruising, 3 cases of phlebitis, 2 cases of recanalization, and 1 case of neovascularization.
Conclusion: VENISTARⓡ, the new radiofrequency thermal ablation device, was effective and safe for treatment of varicose veins. However, as the follow up duration of the participants was relatively short, generalization of the findings was limited. In the future, long-term studies must be conducted.
