980nm laser + bare fiber VS 1470nm laser + radial fiber



Objectives: The aim of this study is to compare efficacy, early postoperative morbidity and patient comfort of two laser wavelengths and fibre types in treatment of great saphenous vein (GSV) incompetence resulting in varicosities of the lower limb.
Design: Prospective randomised clinical trial.
Materials and Methods: Sixty patients (106 limbs) were randomised into two groups. They were treated with bare-tip fibres and a 980 nm laser in group 1 and radial fibres and 1470 nm laser in group 2 in order to ablate the GSV. Local pain, ecchymosis, induration and paraesthesia in treated regions, distance from skin, vein diameter, treated vein length, tumescent anesthesia volume, delivered energy and patient satisfaction were recorded. Follow-up visits were planned on the 2nd postoperative day, 7th day, 1st, 2nd, 3rd and 6th months.
Results: Mean GSV diameters at saphenofemoral junction and knee levels were 12.1 S.D. 4.3 mm and 8.2 S.D. 2.4 mm, and 11.8 S.D. 4.1 mm and 7.9 S.D. 2.6 mm respectively in groups 1 and 2. There were 14 patients with induration, 13 with ecchymosis and nine minimal paraes-thesia in group 1 and no or minimal local pain, minimum ecchymosis or induration in group 2.Duration of pain and need for analgesia was also lower in group 2 (p < 0.05). There was signif-icant difference on postoperative day 2, day 7 and 1st month control in favor of group 2 invenous clinical severity scores (VCSS).
Conclusion: Treatment of the GSV by endovenous laser ablation using a 1470 nm laser and a radial fiber resulted in less postoperative pain and better VCSS scores in the first month than treatment with a 980 nm laser and a bare-tip fiber
