“…At the same time, the maximum power of EVEW devel ops at the moment of minimal resistance of the venous wall and subsequently decreases as the resistance in creases. In the conditions of optimal contact of the working part of the WET and the vein, the completion of the OC welding always occurs at the moment of the development of denaturation of the venous wall, regardless of the diameter of the vein [9,10]. Thus, the influence of subjective factors on the result of ablation is limited by the choice of the access point and the position of the working part of the tool and the tech nique of performing tumescent anesthesia.…”

“…The EVEW method is based on the technology of electric welding of living tissues and involves the ablation of incompetent subcutaneous venous trunks under the influence of high-frequency modulated electric current, the parameters of which during the operating cycle (OC) are generated automatically de pending on the impedance dynamics and structural changes of the venous wall [8]. Unlike other methods of thermal ablation, EVEW does not require the oper ator to select, adjust and control exposure parameters, and is characterized by relatively low heating and is not accompanied by coagulation necrosis of the ve nous wall [9,10].…”

The aim of the work: to determine the effectiveness and results of the clinical application of EVEZ with the local treatment of CVI of complicated TV with the help of PRP; to increase the level of efficiency and safety of treatment of patients with CVI. Materials and methods. The results of 112 EVEW operations in 93 patients with CVI C5–C6 were analyzed. EVEW of the GSV was performed in 90 cases, SSV in 22. The diameters of the jugular segments of the veins were 5.7–28.4 mm, the area of the VLU was 8–84 cm2. The EVEW device provides electrothermal ablation of veins due to denaturation of the venous wall. The duration and power of EVEW is determined automatically, according to the coefficient of relative resistance. The proposed method of preoperative preparation speeds up the processes of VLU cleaning and regeneration. Results and Discussion. PP is absent in 74 (66.1%) cases, moderate PP in 38 (33.9 %). After 2 years, fibrosis of target veins in 100 % of cases. Paresthesia lasting up to 14 days in 4.5 %. The proposed algorithm of preoperative preparation led to the clearing of the VLU in (14±7.6) days and healing in (27±4.5) days in 95 % of patients. Automatic EVEW algorithm allows to increase the level of efficiency and safety of surgical treatment of patients with veins of large diameters and their extrafascial location, severe forms of CVI with VLU. The use of a complex of preoperative preparation made it possible to achieve complete clearing of the VLU in 90 % of patients by (14±7.6) days. Injections of PRP in the VLU area and the use of EVEW led to epithelization in (27±4.5) days in 95 % of patients.

Aim: The purpose was to improve the results of treatment of chronic diseases of the lower extremities veins by using endovenous high-frequency electric welding in automatic mode, and to evaluate the obtained results. Materials and methods: The results of treatment of 146 patients with chronic diseases of the lower extremities veins in the period from 2018 to 2023 were analyzed. There were 87 women (59.59%) and 59 men (40.41%). Reflux in the great saphenous vein was observed in 124 (84.93%) patients, in the small saphenous vein – in 22 (15.07%). 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. The stability of occlusion in the great and small saphenous veins after endovenous high-frequency electric welding was assessed on the basis of ultrasound examination at 7 days, 1, 3, 6, 12 months and more. Results: The postoperative pain along the treated vein was noted in 2 (1.36%) patients, discomfort – in 124 (84.93%), feeling of a pull on the inner surface of the thigh – in 65 (44.52%), paresthesias in the thigh or lower leg – in 6 (3.57%), inflammatory infiltration along the treated vein – in 1 (0.68%), recurrence of the disease – in 2 (1.19%). 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. The gentler energy effect of endovenous high-frequency electric welding on the vein walls compared to endovasal laser ablation and radiofrequency ablation reduces the manifestations of side effects and complications from the paravascular tissues. Conclusions: The method of endovenous high-frequency electric welding is an effective treatment of chronic diseases of the lower extremities veins, leading to complete vein ablation in 100% of cases within a follow-up period of 12 months or more.
