NCT00006182

Brief Summary

To determine how long blood transfusions are needed for primary stroke prevention. Also, to determine the duration of risk associated with abnormal transcranial Doppler ultrasound (TCD) and to determine the specificity of the stroke risk model developed in STOP 1 in patients with abnormal TCD measurements.
