Primary stroke prevention in Nigerian children with sickle cell disease (SPIN): challenges of conducting a feasibility trial.

Abstract

The majority of children with sickle cell disease (SCD), approximately 75%, are born in sub-Saharan Africa. For children with elevated transcranial Doppler (TCD) velocity, regular blood transfusion therapy for primary stroke prevention is standard care in high income countries, but is not feasible in sub-Saharan Africa.
