Prediction Model Based on Computed Tomography Liver Volume for the Short-term Mortality in Hepatitis B Related Acute-on-Chronic

HBV-ACLF deteriorates rapidly with a high short-term mortality and early identification and accurate prognostic prediction may be the key to make clinical decision and improve survival rate. Liver volume, non-invasively reflects the balance of structural collapse with hepatic regeneration, predicting the prognosis of liver diseases. However, there is no idea whether the liver volume is an indicator to predict the mortality of HBV-ACLF patients. The present study evaluated the difference of liver volume between 28-day survival group and non-survivals and developed a new prognostic model based on liver volume . This study highlighted the significance of liver morphology in predicting the outcome of HBV-ACLF for the first time.

• Biochemical examinations were available within 3 days before or after CT scan

Exclusion criteria

• Patients with evidence of non-B hepatitis virus: alcohol abuse leads to liver failure, autoimmune leads to liver failure, oxic or other causes that might lead to liver failure
• Past or current hepatocellular carcinoma
