Impairment of Cerebrovascular Hemodynamics in Patients With Severe and Milder Forms of Sickle Cell Disease

Autor: Liza Afzali-Hashemi, Koen P. A. Baas, Anouk Schrantee, Bram F. Coolen, Matthias J. P. van Osch, Stefan M. Spann, Erfan Nur, John C. Wood, Bart J. Biemond, Aart J. Nederveen

Publikováno v: Frontiers in Physiology, Vol 12 (2021)

In patients with sickle cell disease (SCD), cerebral blood flow (CBF) is elevated to counteract anemia and maintain oxygen supply to the brain. This may exhaust the vasodilating capacity of the vessels, possibly increasing the risk of silent cerebral
