Case Report: Spherocytic Hemolytic Anemia after Envenomation by Long-Nosed Viper ().

Snakebite envenoming is a major health issue in many parts of the world, especially in rural areas. is the commonest cause of snakebite in Greece. We report our experience with a patient bitten by such a snake, who developed massive intravascular hemolysis characterized by a spherocytic rather than microangiopathic hemolytic picture. This case illustrates the potential of snakebite envenoming to cause spherocytic hemolytic anemia associated with hemoglobinuria and acute renal failure, and represents the first report of in this context. Another important point is that antivenom was rapidly effective in reversing spherocytic hemolytic anemia, even though several hours had elapsed since the bite.
