Comparison of 940 nm and 1470 nm Bare Fibers in Treatment of Great Saphenous Vein Insufficiency

Objective: Endovenous laser ablation has been easily accepted since present surgical methods are major interventions. The aim of this study was to investigate the effectiveness and early postoperative morbidities of two different wavelengths used in endovenous laser ablation. Material and Methods: Randomly selected 200 patients were included in the study. In group 1, 125 lower extremities of 106 patients were treated with 940 nm laser wavelength. In group 2, 110 lower extremities of 94 patients were treated with 1470 nm laser wavelength. Results: Percutaneous intervention and endovenous insertion of fiber were successfully completed in both groups. Only induration was statistically significantly more in group 1. There were no statistically significant differences for the other postoperative parameters between two groups. Conclusion: Treatment of the great saphenous vein by endovenous laser ablation using a 1470 nm laser wavelength resulted in less postoperative pain. Although it was not statistically significant, the duration of pain was longer in the group with more induration. We suppose that vein should not be perforated in order not to increase postoperative morbidities.
