TREATMENT OF TROPHIC COMPLICATIONS IN DECOMPENSATED FORMS OF IMPAIRED ARTERIAL BLOOD CIRCULATION OF THE LOWER EXTREMITIES

Abstract

Summary. The aim of the study was to study the clinical effectiveness of using the developed method of cryopreservation on wound surfaces using a cryopreservation device. Materials and methods. 87 patients with ulcerative-necrotic defects of the lower legs and feet were selected for the study. The condition for inclusion in the study was Phase I of the wound process. Patients were divided into the main and comparison groups. The main group included 41 patients who had their wounds cleaned according to the proposed method, and the comparison group consisted of 46 patients who underwent surgical treatment. Results. The use of cryodestruction of the surface of trophic ulcers of arterial etiology led to rapid cleaning of necrotic masses, fibrin, a decrease in exudation and pain intensity, and the disappearance of unpleasant odors. The effectiveness of the methods lies in the fact that not only necrotic components of the wound surface, fibrin films, as well as the surface layers of ulcer surface cells are destroyed, that is, phenotypically altered cells of the wound edge and base are removed, leading to a violation of regeneration processes. Conclusions. Debridment methods based on the use of controlled cryodestruction of pathological tissues on the surface of trophic ulcers accelerate the transition of the wound process to phase II by 25% in patients with trophic ulcers with critical ischemia of the lower extremities.
