Abstract:
:The exact pathogenesis of centrilobular necrosis following congestion of the liver is still unknown. We reviewed the clinical data related to systemic circulatory disturbance and histopathology of the liver and the gut in 320 autopsy subjects. Congestion of the liver alone was associated only with atrophy and loss of hepatocytes in centrilobular areas, but not with hepatocellular coagulative necrosis. In many patients with coagulative necrosis of centrilobular hepatocytes and congestion of the liver, fibrin thrombi and neutrophil infiltration in the sinusoids, which are the characteristic histopathological features of the liver in endotoxaemia, were found in and around the necrotic area. Congestion, erosion or haemorrhage of the intestinal mucosa, which may allow entrance of endotoxin into the liver through the portal vein, was seen in such patients. Prolonged hypotension or shock, which may lead to portal endotoxaemia, was present in half the patients with centrilobular necrosis and congestion of the liver. These results suggest that not only congestion of the liver but also portal endotoxaemia may be involved in the pathogenesis of centrilobular necrosis in patients with congestion of the liver.
