摘要：

The clinicopathological features of 38 patients admitted consecutively for fulminant hepatic failure were studied. Histopathological material was reviewed in all patients. Both percutaneous and whole livers (either explanted or autopsy specimens) were available in 16 patients: whole livers only in 12 patients and biopsy specimens only in 10 patients. All patients were negative for antibodies to hepatitis C, whereas 24% had hepatitis B infection and 10% had adverse drug reactions. Livers from 75% of patients showed confluent hepatic necrosis. However, there was considerable variability in the extent of necrosis, and biopsy specimens from about 50% of the most severely affected livers showed only minimal bridging necrosis. In patients with massive hepatic necrosis, percutaneous liver biopsy specimens were frequently misleading because of regional inhomogeneities. Interestingly, five patients (13%) had established cirrhosis at the time of diagnosis. The best clinical predictors of surviva
