[Frostbite as a problem for dermatoplastic surgery].

An analysis of the 35-years experiences with treatment of 621 patients with the IV-degree frostbite of hands and feet is presented. The surgical strategy of treatment of frostbite has undergone considerable evolution for these years. In addition to classical surgical treatment, the surgeons began to widely use methods of dermo-plastic surgery which allowed not only to save the maximum possible length of the extremity segment stump, but also to reduce the frequency of purulent complications and reamputations and thus to shorten the duration of hospital treatment.

[Free transplantation of skin flaps with axial blood supply in IV degree burns].

The article analyses the results of free transplantation of skin grafts with axial blood supply in 45 patients with IV degree burns and their sequelae. Bearing in mind the peculiarities of damage to the tissues and vessels in a thermal trauma, it is advisable to anastomose the vein grafts with the large subcutaneous veins. Skin grafts with a long vascular pedicle are preferable.

[Various aspects of organization of microsurgical autologous transplantation of composite skin flaps].

An experience with 137 microsurgical transplantations enabled the authors to consider questions of rational organization of these complex, and severe operations. Different variants of work of the second team of surgeons are analyzed aimed at shortening the duration of the operation and getting less load by its participants.

[Changes in oxygen and carbon dioxide tension in skin capillaries as an indicator of the status of blood supply of compound skin flaps].

The authors consider that the transcutaneous determination of the level of pO2 and pCO2 at early terms after operation in free and pedicled skin flaps allows to actively estimate the state their blood supply and to detect the alterations before the appearance of distinct clinical symptoms of arterial or venous thrombosis.

[The first experience with crural plastic surgery using island composite skin flaps].

An analysis of literature data, topographo-anatomical studies of 23 lower extremities and an experience with using 18 island fasciocutaneous flaps of the lower leg are presented. The article describes the possibilities of using a new donor area for plasty of limited defects of the lower leg and foot after various traumas and their sequelae.

[Dynamics of indicators of dermocytograms and reparative capacity of the body in burns].

The investigation of dermocytograms by a modified method of the "skin window" in 101 patients with different square surfaces of deep burns has shown that the dynamics of mononuclear content is dependent on the injury degree. Lower parameters of mononuclear content in dermocytograms during the course of treatment correspond to the disturbance of reparative capacities of the organism in groups of patients with the complicated course of the disease. The "skin window" test can be used for the treatment since it shows the degree of the burn trauma dynamics and character of its course, facilitates the prognosis of complications.

[Plastic surgery using cutaneo-fascial flaps in the treatment of burns].

Results of 67 plasties with fasciocutaneous flaps in 59 patients operated upon for burns and their sequellae are described. The correlation of length and width of the flaps was from 1.5:1 and 3:1.

[Surgical treatment of 4th degree frostbite of the extremities].

The aim of the operative treatment of IV degree frostbite is not only to save the bone stump, but also to achieve its functional fitness after primary surgery or in future due to creation of favourable conditions for the following reconstructive operations. Dermo-plastic operations, both well-known and modified ones were used. The experience of the authors includes 347 patients.

[Plastic surgery using islet triangular flaps in 4th degree frostbite of the fingers].

In 36 patients with IV degree frostbites the guillotine amputation of 91 fingers was performed at the level of the ungual, middle and distal thirds of main phalanges. The wound of the stump butt was substituted by an islet triangular flap. It gave a functionally adaptable stump without shortening the bone phalange.

[Classification of the methods of skin autoplasty].

The authors propose a classification of methods of skin plasty. It is based on two main features: the anatomical structure of the autoplasty material and the state of its blood circulation.

[Pathogenesis and treatment of late lysis of autodermotransplants in burns].

Forms of late lysis of autodermotransplants were studied in 35 burned patients. The authors distinguish a "simple" lysis (20 patients) resulting from autoimmune processes and lysis in acute inflammation (5 patients) due to pathogenic microflora.
