Acute liver failure is the appearance of severe complications rapidly after the first signs (such as jaundice) of liver disease, and indicates that the liver has sustained severe damage (loss of function of 80–90% of liver cells).
The Clichy criteria are a group of criteria proposed in determining the survival of individuals with acute liver failure. It was based on a study of patients presenting with viral hepatitis, of which individuals with the lowest survival were identified. Two criteria predicted the prognosis of patients with poor survival:
The King's College criteria were described in a seminal publication in 1989 by J.G. O'Grady and colleagues from King's College School of Medicine. [2] 588 patients with acute liver failure who presented to King's College Hospital from 1973 to 1985 were assessed retrospectively to determine if there were particular clinical features or tests that correlated poorly with prognosis.
Liver failure is the inability of the liver to perform its normal synthetic and metabolic functions as part of normal physiology. Two forms are recognised, acute and chronic (cirrhosis). [ 1 ] Recently, a third form of liver failure known as acute-on-chronic liver failure ( ACLF ) is increasingly being recognized.

The hepatopulmonary syndrome results from the formation of microscopic intrapulmonary arteriovenous dilatations in patients with both chronic, and far less commonly acute liver failure. The mechanism is unknown but is thought to be due to increased liver production or decreased liver clearance of vasodilators, possibly involving nitric oxide. [1]
Ischemic hepatitis, also known as shock liver, is a condition defined as an acute liver injury caused by insufficient blood flow (and consequently insufficient oxygen delivery) to the liver. [5] The decreased blood flow ( perfusion ) to the liver is usually due to shock or low blood pressure.
Hepatorenal syndrome is a particular and common type of kidney failure that affects individuals with liver cirrhosis or, less commonly, with fulminant liver failure. [1] The syndrome involves constriction of the blood vessels of the kidneys and dilation of blood vessels in the splanchnic circulation, which supplies the intestines. [ 2 ]
