Aim: To compare the efficacy of endovenous radiofrequency ablation and conventional surgery in treating patients with primary varicose veins. Materials & methods: 40 patients with presence of primary varicose veins were included and were broadly divided into two study groups as follows: Group 1: Patients who were treated with endovenous radiofrequency ablation; and Group 2: Patients who were treated with conventional surgery. Complete demographic and clinical details of all the patients were obtained. All the patients were categorized according to CEAP score. Venous color Doppler was sued for diagnosing venous insufficiency. All the patients were treated according to their respective study groups. Follow-up was done and assessment of patients was carried out on successive visits. VAS score was used for assessing the postoperative pain. Return to normal activity was evaluated by assessing the BRAVVO score. All the results were recorded in Microsoft excel sheet and were analysed by SPSS software. Results: In the Group 1, mean VAS at immediate postoperatively, one week postoperatively and one month postoperatively was found to be 4.96, 2.95 and 0 respectively. In the Group 2, mean VAS at immediate postoperatively, one week postoperatively and one month postoperatively was found to be 7.11, 4.12 and 0.73 respectively. Wound infection was absent in group 1 while it was present in 20 percent of the patients of the group 2. Mean BRAAVO score among the patients of the Group 1 and group 2 at 10th day postoperative was 14.2 and 11.9 respectively. Mean time to return to normal activity among the patients of the Group 1 (7.9 days) was significantly lower in comparison to the patients of the Group 2 (15.5 days). Conclusion: Endovenous radiofrequency ablation is better as compared to conventional surgery for treating patients with primary varicose veins. Key words: Varicose, Veins, Radiofrequency ablation
