Abstract

BACKGROUND: Varicose veins of the lower limbs have a high prevalence worldwide. New treatment techniques have been developed with the objectives of improving patients' quality of life and reducing recovery times. OBJECTIVE: To evaluate patients with incompetent saphenous veins treated using conventional saphenectomy or radiofrequency ablation (RF), in terms of postoperative status. METHODS: From May 2012 to April 2013 146 varicose veins patients with saphenous insufficiency, 90 of whom were treated with conventional surgery (G1) and 56 with RF ablation (G2), were evaluated prospectively. RESULTS: In G1, 88.61% of patients complained of postoperative pain and needed to take analgesics, compared with 28.85% in G2 (p<0.05). Mean pain rating on an analog scale from 0 to 10 was 3.91&#177;2.13 points for G1 and 1.76&#177;3.01 points for G2 (p<0.05). Recovery periods ranged from 26.63&#177;13.3 days to 18.26&#177;19.37 days, for G1 and G2 respectively. Mean time taken to become totally asymptomatic was 66.78&#177;60.9 days for G1 and 38.38&#177;46.8 days for G2 (p<0.05). CONCLUSIONS: The RF treatment method caused less postoperative pain and resulted in earlier recovery, when compared to conventional saphenectomy
