Free skin transplantation technique for treating wounds in plastic and reconstructive surgery

The main indications for the application of the technique of free skin transplantation are extensive skin defects in places with high skin tension. Researches were conducted on 15 dogs aged from 1.5 to 9 years old, in the conditions of the veterinary clinic of orthopedics, traumatology and intensive care, St. Petersburg. 13 dogs with wound surfaces ranging in size from 4 to 8 cm in the distal parts of the limbs, obtained as a result of injury, and after carrying out surgical interventions for the removal of tumors. 2 dogs with wound surfaces ranging in size from 8 to 14 cm in the trunk region as a result of a burn disease obtained from a heating pad. The depth of the lesions was 1.5-2 cm. From 7 to 11% of the body surface was susceptible to burn injury. Before surgery, a clinical examination was performed, laboratory blood tests - clinical and biochemical blood tests, cardiac echocardiography. This is due to the fact that with the healing of large wounds on secondary tension, scar tissue forms that prevents the normal functioning of this area and at the same time, changes the aesthetic appearance of the affected area of the body. Solve this problem with skin transplant. In this regard, the purpose of our study was a detailed study of the technique of free skin graft and the features of postoperative care. In 80% of the animals, who had been transplanted with free stratified grafts to close skin defects, complete engraftment of the flaps was observed. 15% partial engraftment, and 5% had a flap tearing. Incomplete engraftment of flaps was observed on extensive skin defects, in the area of bone tissue not covered with muscle or granulation tissue, and wounds in which necrotic tissue is partially present. Rejection of the flap occurred with one transplantation on the trunk, it was not possible to properly fix bandage bandages in this area, as a result of which the nutrition and engraftment of the flap was disrupted. The obtained results of treatment indicate that skin grafting with the help of a free skin grafts is the fastest way to heal extensive skin defects, wound surfaces of distal limbs with the best functional and cosmetic effects.
