Ischemic Hepatitis
Diagnosis of Ischemic Hepatitis
Clinical evaluation and liver tests Doppler ultrasonography, MRI, or arteriography Ischemic hepatitis is suspected in patients who have risk factors and laboratory abnormalities: Serum aminotransferase increases dramatically (eg, to 1000 to 3000 IU/L). Lactic dehydrogenase (LDH) increases within hours of ischemia (unlike acute viral hepatitis). Serum bilirubin increases modestly, only to≤4 times its normal level. Prothrombin time/international normalized ratio (PT/INR) increases. Imaging Tests of the Liver and Gallbladder helps define the cause: Doppler ultrasonography, MRI, or arteriography can identify an obstructed hepatic artery or
