Modern possibilities of usage of the endovenous welding in the treatment of patients with chronic venous diseases: method basics and applications results

A complex minimally invasive approach to the treatment of patients with complicated forms of chronic venous insufficiency

“…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].…”
