Abstract:
Objective:To investigate the safety and efficacy of a modified radiofrequency ablation（RFA）treatment method for primary great saphenous vein varicose.Methods:Clinical data of 90 patients with primary great saphenous vein varicose treated with ultrasound-guided RFA from January 2021 to April 2024 in the Ultrasound Department of the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. Among them，45 patients were treated with traditional RFA treatment method（traditional group）and 45 patients were treated with improved RFA treatment method（improved group）. Number of punctures，operation time，foam hardener dosage，intraoperative and postoperative complications were recorded in the two groups. The preoperative and postoperative venous clinical severity score（VCSS）and chronic venous insufficiency questionnaire（CIVIQ-14）were compared. The closure rate and recurrence rate of great saphenous vein varicose were followed up and the efficacy of the two methods were analyzed.Results:The success rate of the improved group and the traditional group was 100%.The number of punctures in the improved group was less than those of the traditional group［1（1，1） vs. 2（2，3）， Z = -7.431， P<0.001］，and the operation time of the modified group was shorter than that of the traditional group［（15.89 ± 3.63）min vs.（30.91 ± 5.58）min， t=-15.145， P<0.001］，the average volume of lauryl foam was lower than that of the traditional RFA group［（7.96 ± 2.36）ml vs.（15.69 ± 2.89）ml， t=-13.892， P<0.001］. The incidence of complications was similar between the two groups，with no statistical significance（all P>0.05）. Postoperative VCSS and CIVIQ-14 scores were significantly improved compared with before（all P<0.001），with no statistical significance between the two groups（all P>0.05）. At 12 months after the operation，there was no significant difference in the closure rate of the saphenous vein between the improved group and the traditional group（ P>0.05），and the recurrence rate of varicose veins in both groups was 0. Conclusions:This modified RFA treatment method for the treatment of lower extremity varicose veins is minimally invasive，safe，and has the same efficacy as the traditional RFA treatment method. Compared with the traditional RFA treatment method，the modified RFA treatment method has the advantages of convenient operation，less puncture times and shorter operation time，and is worthy of clinical promotion.
