title: [The functional behavior of peripheral circulation in cryogenic surgery].
abstract: The reactive behaviour of little vessels of the circulatory periphery against the effect of extremely deep temperatures was examined in a sense of a microflow measurement by means of the intravital microcinematography. The results obtained by mathematical analysis of the single figure demonstrate that the vessels of microcirculation are remarkably resistant against rapid withdrawal of heat. In this way the quickly recovered blood-flow in the periphery of circulation can reduce detrimentally the time of tissue thawing treated by cryosurgery. Both the shortening of the thawing phase after cryosurgery conditioned by hemodynamics and the development of a cold edema can be met by experimentally confirmed adrenergic influence of the vasoconstriction under local anesthesia.
