Extreme heatstroke causing fulminant hepatic failure requiring liver transplantation: a case report

Introduction: Exertional heatstroke with liver involvement is a rare and potentially fatal condition. In this setting, fulminant hepatic failure (FHF) occurs as a result of severe hypoxic hepatitis.

Case report: We report the case of a young male athlete who developed exertional heatstroke associated with rhabdomyolysis and hypoxic hepatitis while running the final stages of an ultra-marathon (62 km). The patient rapidly developed multiorgan failure, including fulminant hepatic failure, requiring intensive care admission for mechanical ventilation, hemodialysis, and inotropic support. He failed to improve with supportive measures and underwent an emergency hepatectomy followed by orthotopic liver transplant, after which he recovered completely.

Conclusions: We discuss the rationale for liver transplantation in this setting, possible alternative treatments, and the pathophysiology of fulminant liver failure in this rare case.
