    Introduction. The aim of this study was to investigate the effects of total vascular exclusion (TVE) on the liver during the early period of reperfusion. Materials and methods. Forty Wistar-Albino rats were divided into four groups. Portal pedicle clamping (groups 1 and 2) or TVE (groups 3 and 4) were applied for 10 minutes. Samples were collected at the time of clamp release (groups 1 and 3) and at 30 minutes of reperfusion (groups 2 and 4). We examined oxidative injury to and histopathology of the liver. Results. Oxidative stress was more prominent with TVE application. Significant alterations were shown in hepatic superoxide dismutase, catalase, glutathione, and glutathione S-transferase levels. The levels of malondialdehyde and myeloperoxidase were not altered significantly. Conclusion. Inflow-outflow occlusion of the liver causes more oxidative stress compared with inflow occlusion.
