Stroke risk according to transcranial Doppler measurements in children with sickle cell disease
Kaplan-Meier survival analysis showing differences in stroke-free survival among patients classified according to their highest velocity in the internal carotid or middle cerebral artery on either side. In cases where multiple transcranial Dopplers (TCDs) were performed, follow-up was computed from the time the TCD first reached the cutoff point. Refer to UpToDate content on stroke prevention in SCD for further discussion of the use of TCD screening.
