Comparing the Efficacy of Radiofrequency Ablation Versus Laser Ablation for Chronic Venous Insufficiency in the Lower Extremities: a Vietnamese Report

Non-randomized comparative study of three methods for great saphenous vein ablation associated with mini-phlebectomy; 48 months clinical and sonographic outcome

Background

Varicose veins are one of the earliest clinical features of superficial venous insufficiency (SVI) of the lower limbs that affects around 20-40% of the population with a lot of burden on patients' quality of life (QoL) and health systems if left untreated. They are defined as subcutaneous veins in the lower extremities which are dilated to ≥3 mm in diameter in the upright position and retrograde flow of >0.5 s in duration. (VVs) could occur in the great saphenous vein (GSV) or small saphenous vein (SSV) and/or in any of their tributaries.

Methods

A prospective non-randomized comparative study for three methods of treatment of varicose veins was conducted. All symptomatic varicose veins with Clinical, Etiological, Anatomical, Pathophysiological (CEAP) Clinical classes of 2 or greater and demonstrated venous reflux with a duration of 0.5 s or greater on duplex ultrasound imaging GSV larger than 10 mm in diameter by duplex ultrasound were included.

Results

A total of 150 patients with 183 legs in all three groups are treated. The mean age of the patients in all groups was comparable (37.32) years, and a total of 87% were women. Demographic and preoperative clinical features, presentations, and anatomic characteristics were comparable in all groups. Disfigurement was the main presenting complaint in all. All postoperative complications were significantly higher in the group of surgery over 48 months of follow up the degree of satisfaction measured by VCSS score was highest among the RFA group followed by the EVLA group.

Conclusion

The results of our study suggest that the long-term results of endovenous thermal ablation methods (EVLA, RFA) are superior to open surgery for the management of varicose veins, with the RFA group showing better results in terms of improvement in QoL based on VCSS compared to the EVLA group.
