Centrilobular necrosis of liver may be seen with

CCl4 is hepatotoxic. Centrilobular necrosis seen in CVC liver. Causes: right sided hea failure. Mechanism: dilatation of central veins-Transmission of increased venous pressure to the sinusoids-dilatation of sinusoids-ischemic necrosis of hepatocytes in centrilobular region. Gross: congested centrilobular area appear dark red brown, peripoal region is better oxygenated hence appear pale Microscopy: centrilobular region: congestion, hemorrhage, thickening of Central veins and fibrosis, centrilobular hepatocyte necrosis. Peripoal region: fatty change in hepatocytes. GENERAL AND SYSTEMIC PATHOLOGY RAMDAS NAYAK PGNO.89
