Also known as shock liver, is condiation where the liver is injured acutely due to lack of blood flow for any number of reasons. This can occur in states of shock (cardiac, septic, neurogenic, less commonly anaphylactic), or prolonged hypoxemia for any reason. The inflammatory process within the liver related to this ischemic damage is referred to as ischemic hepatitis.
