[Application of cryogenic stimulation in treatment of chronic wounds]

The authors have studied alterations occurring both in the ultrastructure of the cell matrix and in the microcirculatory bed of the chronic wound after local exposure to cryoagent. The up-to-date effective methods including laser Doppler flowmetry were used followed by correct statistical processing of the data obtained. The cryogenic stimulation of the wound was shown to result in considerably improved perfusion of the microcirculatory bed, epithelization and remodeling of the scar. It allowed transformation of a chronic process into acute and thus led to considerably accelerated process of regeneration. The developed method of cryogenic treatment of the chronic wound was used in 35 patients, allowed quicker healing of the chronic wounds and made ambulatory treatment of the patients 3 weeks shorter.
