Cryosurgery in diffuse hepatic diseases

Comparative studying, using histological and biomicroscopic methods, of the dosed cryohepatodestruction (CHD), periarterial cryodenervation of hepatic artery (CDHA) and their concomitant application influence on the dynamics of hepatic restoration processes in experimental cirrhosis was performed. The investigations were done on 215 male rats owing body mass 200-280 g in a not changed and pathologically changed liver. There was shown, that CDHA promotes changes in hepatic tissue microhemocirculation, as well as the enhancement of the sinusoidal vessels diameter and relative square of vascular bed. CHD stimulates the reparative processes course in a pathologically changed organ. There was established, that while simultaneous application of two cryosurgical methods, the velocity and grade of restoration processes in cirrhotically-changed liver are enhanced in comparison with such indices changes while separate usage of these two methods.
