    Abstract:
    Hepatic oxygen supply, energy charge (EC), and histology were examined comparatively in dogs with portal vein anastomosis (PVA group), and PA in addition to PVA (PA group). The PVA group showed a lower level of hepatic oxygen supply than those of the PA group throughout the experimental period, and also showed decreases of adenosine triphosphate (ATP) and EC level after blood perfusion. In contrast, the oxygen supply and consumption were stable in the PA group. A temporary fall of ATP level was followed by recovery to the preperfusion level in the PA group. Histological examination indicated the collapse of hepatic cords with granular and vacuolar degeneration in only the PVA group. These findings suggested that PA, when supplemented to PVA, is an available technique for preventing hepatic failure caused by ischemic conditions.
