Background: The most common method for minimally invasive treatment of varicose veins is endovenous laser ablation (EVLA), which is characterized by high efficiency in cases of incompetent vein segment diameter less than 20 mm and a dose-dependent spectrum of complications, which determines the relevance of the search for a new method of thermal ablation with less tissue heating and a more advanced control algorithm.

Methods: In this study we retrospectively compared the results of endovenous ablation of saphenous veins in patients with the lower extremities chronic venous insufficiency classed С2-6ЕрsАsрPrusing laser coagulation of 1470 nm (group 1 (the EVLA) – 526 people) and electric welding (group 2 (the EVEW) – 223 people). The effectiveness of the treatment was carried out taking into account objective and subjective data. Statistical analysis was performed using the Microsoft Excel 2016 software package.

Results: As a result of the treatment, after 6 months, the partial recanalization of saphenous veins was observed in 4% of all cases for the 1st group, and 0% for the second (p>0.05 by the χ2 parameter). Relapses in the first group were related to vessel ostial diameter above 21 mm. When analyzing the patients quality of life on the CIVIQ scale, both methods were equally effective. The endovenous electric welding method has the simple principle of electric into heat energy transformation, as well as the possibility for self-regulation of the electrode exposure duration in the vein lumen, which allows to occlude saphenous veins up to 30 mm in diameter without recurrences within 6 months of postoperative period.

Conclusion: The EVEW is an effective analogue of the EVLA with a higher safety profile and an advanced control algorithm.
