Summary

Brain edema causing intracranial hypertension is a major cause of death in acute liver failure. Gut-derived neurotoxins like ammonia are implicated, necessitating specialized care and liver transplantation for improved outcomes.

Area of Science:

  • Hepatology
  • Neurology
  • Critical Care Medicine

Context:

  • Acute liver failure (ALF) frequently causes brain oedema and intracranial hypertension, a primary driver of mortality.
  • The exact mechanisms of cerebral complications in ALF are not fully elucidated.
  • Gut-derived neurotoxins, particularly ammonia, are increasingly recognized as critical inducers of cerebral osmotic and perfusion issues.

Purpose:

  • To review the common etiologies of ALF.
  • To outline standard supportive care for brain oedema and intracranial hypertension in ALF.
  • To discuss emerging therapeutic strategies for managing cerebral complications in ALF.

Summary:

  • Brain oedema and intracranial hypertension are critical complications in acute liver failure, significantly contributing to patient mortality.

  • Pathogenic pathways involve gut-derived neurotoxins, such as ammonia, impacting cerebral osmolality and perfusion.
  • Multidisciplinary management in specialized centers, including consideration for liver transplantation, is essential for improving outcomes.

    • Impact:

    • This review provides a comprehensive overview of ALF-associated brain oedema and intracranial hypertension.
    • It highlights current management standards and explores future therapeutic avenues.
    • Emphasizes the critical role of liver transplantation in improving survival rates for ALF patients with cerebral complications.
