The analysis investigates the relationship between cerebral blood flow and vasculopathy in children with sickle cell anemia undergoing chronic transfusion.
Conducted a secondary analysis on 28 transfusion events in children with HbSS on chronic transfusion therapy.
Utilized diffuse correlation spectroscopy to measure cerebral blood flow pre- and post-transfusion.
Assessed vasculopathy via clinical MRI/MRA reports to categorize patient status.
A total of 39% of patients showed evidence of vasculopathy at the time of transfusion.
Lower pre-transfusion cerebral blood flow significantly associated with vasculopathy status (p<0.001).
Multivariate models highlight the correlation between vascular status and cerebral blood flow response post-transfusion.
