The evaluation was done in the sphere of preoperative preparation trophic ulcer in patients with CVI using the proposed tactics of mechanochemical debridement and elimination of vertical venous reflux EVEZ method, in comparison with standard preoperative management tactics and EVLT of saphenous veins. It is established that the proposed tactics of preoperative preparation are more effective than classical approaches.
Purpose. The use of the EVEZ method in combination with the proposed preoperative preparation of trophic ulcers in the treatment of CVI was determined to be effective.
Materials and methods. An analysis of the treatment of 68 patients with CVI C6 clinical class was performed. The patient of the main group received the EVEZ treatment tributaries and perforating veins with preoperative trophic preparation ulcers, which includes: active mechanochemical debridement and control moisture balance in the wound, installation of negative pressure wound therapy system, platelet rich plasma therapy, application drugs based on diosmin and hesperidin. The proposed scheme of preoperative preparation has the following algorithm:

Taking a smear from the sore to determine the bacterial spectrum and subsequent rational antibacterial therapy following the results of the antibioticogram;
Active mechanochemical debridement with solutions of 0.1% polyaminopropyl biguanide + 0.1% surfactant, povidone-iodine + ethanol + glycerin + laureate 9 and control of moisture balance in the wound with modern hydrogel sore dressings;
Installation of VAC system with a constant negative pressure of 120 mm Hg for 3 days for the first 3 performances of the system. Subsequently, VAC therapy was performed in a constant mode with a pressure of 80-120 mm Hg. in patients with insufficient wound cleanliness;
After active cleaning, PRP therapy was performed, which involves the introduction of platelet-enriched plasma along the edge of the wound to a depth of 3 to 5 mm. The amount of PRP used depended on the size of the defect and ranged from 1 to 2 ml.
All patients of the main group underwent correction of concomitant pathology with systemic use of capillary stabilizing drugs based on diosmin / hesperidin.

Patients in the comparison group received standard preoperative preparation and EVLT. Patients of both groups were outpatient for 6 months. 39 of them (57.35%) were women and 29 (42.65%) were men aged 36 to 78 years. The duration of ulcers ranged from 3 months to 7 years. The following localization of venous trophic ulcers was observed: in the area of the medial bone - in 49 (72%) patients, 10 (14.7%) - on the anterior surface, 9 (13.3%) - on the lateral, posterior, anterior medial or anterolateral surface of the tibia.
Results. Tactics of preoperative preparation that is offered allowed to achieve: reduction of redness and swelling in the main group on 7.3 ± 0.8 days (comparison group 10.2 ± 0.7 days); complete cleaning of the wound from fibrin and necrotic tissues at 9.1 ± 0.5 days (15.0 ± 1.1); the appearance of granulation tissues at day 12.6 ± 0.9 (18 ± 0.7); the appearance of marginal epithelialization at 15.3 ±0.7 days (20 ± 1.1).
Conclusions. The proposed tactics can reduce the term by 1.7 times the preparation of the ulcer for surgery and 1.6 times the healing time of ulcers. The EVEZ method allows performing ablation efficiently and safely trunk great saphenous vein. The use of phlebotonic drugs, which is called Normoven, allows you to accelerate the healing of ulcers and prevent their recurrence.
