Donor liver small droplet macrovesicular steatosis is associated with reduced graft survival after liver transplantation
Modern hepatic steatosis classification includes large droplet macrovesicular (L-MaS), small droplet macrovesicular (S-MaS) and true microvesicular (MiS). Based on previous classification simply describing macrovesicular and microvesicular steatosis, donor livers with ≤30% of hepatocytes with macrosteatosis, which should represent L-MaS, are considered safe to be transplanted, while microsteatosis is usually not considered a risk factor for graft loss.
