[Emergency management of sickle cell disease].

Adult patients with sickle cell disease may present to the emergency department with a broad spectrum of acute clinical manifestations. These acute complications can be life-threatening and require a structured, time-sensitive emergency management approach. Although vaso-occlusive pain crises represent the most frequent cause of presentation, other severe complications-including cerebrovascular events, acute chest syndrome, priapism, and hepatobiliary disorders-may also require immediate medical evaluation. Prompt diagnostic assessment and initiation of appropriate therapy are essential to prevent clinical deterioration and the development of secondary complications.
