Key Points

  • To assess the variations in transcranial Doppler readings among pediatric patients with sickle cell disease and the effectiveness of stroke prevention measures in northeast Brazil.
  • Conducted a cross-sectional study in pediatric patients with sickle cell disease
  • Measured transcranial Doppler screening rates and incidence of stroke
  • Evaluated the implementation of primary stroke prevention recommendations
  • Low transcranial Doppler screening rates were observed in the population
  • High incidence of stroke reported among the pediatric patients
  • Ineffective implementation of stroke prevention strategies noted in the region

Abstract

Despite recommendations, primary stroke prevention is not yet effectively implemented in the northeast of Brazil, as evidenced by low transcranial Doppler screening rates and the high incidence of stroke in the study population.
