Objective: Chronic venous insufficiency, which has a high prevalence rate and a high expense, is an important health problem leading to an apparent decline in work-power and quality of life. Endovenous Laser Ablation (EVLA) currently gains importance in the treatment of great saphenous vein (GSV) insufficiency. The efficiency and adverse effects of EVLA with different wave-lengths are emphasized. The aim of this article is to determine the efficiency and adverse effects of EVLA with 980 nm and 1470 nm wave-lengths. Material and Methods: A total of 86 cases with grade 4 insufficient GSV and absence of deep and perforating vein insufficiencies comprised the study population. The study group was randomized into two groups; in group 1 980 nm bared-fiber, and in group 2 1470 nm radial-fiber catheter was used. The proximal and distal diameters of GSV before the intervention, and the rates of adverse effects and recanalization were determined in the first, fourth and sixth weeks after the intervention. A p value less than 0.05 was regarded as significant. Results: While the diameters of proximal and distal GSV in group 1, including 44 cases, were 6.4±0.87 mm and 5.8±0.71 mm respectively, those values were 6.7±1.72 mm and 5.9±0.62mm in group 2 which included 42 cases. At the end of the first week, the rate of hyperemia (p<0.001) and formation of bullous structures (p=0.03) were higher in group 1. At the end of the fourth week, the rate of hyperpigmentation (p=0.005) was higher in group 1. At the end of the sixth week, while the recanalization rate was lower in group 2 (p=0.058), there was no significant difference. The cumulative rate of the development of deep vein thrombosis between groups (13.6% in group 1, 2.4% in group 2) did not show any difference (p=0.110). Conclusion: The radial-fiber EVLA catheter with 1470 nm wave-length provides both higher efficiency and less adverse effects.
