Abstract
A study was performed to test the hypothesis that host response injury, specifically vascular injury, causes the majority of tissue necrosis at the edge of a frozen region and therefore determines the size of the lesion seen after in vivo freezing. The dorsal skin flap chamber (DSFC) implanted in the Copenhagen rat served as the cryosurgical model. There was a statistical correlation between the region of vascular stasis and the region of tissue necrosis, and the lesion sizes were statistically similar for tumor and normal tissue which are dissimilar save for the presence of a vasculature. The minimum temperature required to cause this damage was much higher than the temperature required for AT-1 cell destruction in vitro, and was similar to temperatures which caused vascular injury in other studies. These results lend support to the addressed hypothesis.
