Abstract
Objective: To evaluate long-term outcomes of radiofrequency ablation (RFA) treatment for great saphenous vein (GSV) insufficiency with the CR45i catheter. Subject and method: Prospective study, cross-sectional description and longitudinal follow-up was performed on 232 patients with 352 legs with chronic lower extremity venous insufficiency manifested by reflux flow > 0.5 seconds on Doppler ultrasound and with clinical grading from C2 to C6, were treated with RFA at Hanoi Heart Hospital from September 2017 to June 2022. Patients were asked about their diseases, clinical examination, lower limb venous Doppler ultrasound, ultrasound-guided intervention and follow-up evaluation up to 18 months after intervention. Result: Functional symptoms decreased significantly after 1 month and persisted for up to 18 months after intervention. CEAP grading after intervention clearly improved from C2-C6, remaining mainly C0-C1. VCSS score decreased from 7.9 ± 1.4 before intervention to 1.1 ± 0.8 after 18 months (p<0.001); CIVIQ-20 score decreased from 44.5 ± 3.9 before intervention to 20.6 ± 2 after 18 months (p<0.001). After 18 months of follow-up, there were 20 cases (5.7%) of vessel revascularization after intervention; the success rate of the procedure was 94.3%. The main complications after intervention were muscle pain (23.9%), and bruising (7.1%). After 18 months of follow-up, 14 cases (3.9%) of EHIT appeared. Conclusion: Treatment of GSV insufficiency with radiofrequency energy is safe and effective with long-term follow-up up to 18 months.
