Elimination of reflux in the great and small saphenous veins was performed by the method of endovenous high-frequency electric welding using the device «High-frequency electrocoagulator EK-300M» (Ukraine) in automatic mode.

Сomplete ablation was achieved in 146 (100%) operated patients. Complete ablation of veins was achieved due to the fact that the parameters of endovenous high-frequency electric welding, which, unlike endovasal laser ablation and radiofrequency ablation, are generated automatically based on the principle of feedback between the device itself and a specific level of impedance of the venous wall, ensure high-quality thermal treatment of all layers of the vein in each individual segment.
