A retrospective cohort study of children with sickle cell anemia (SCA) and strokes was used to test the hypothesis that exchange transfusion at the time of stroke presentation more effectively prevents second strokes than does simple transfusion. Children receiving simple transfusion had a 5-fold greater relative risk (95% confidence interval = 1.3 to 18.6) of second stroke than those receiving exchange transfusion.
