Cerebral autoregulation and cortical perfusion in decompressive surgery for hemispheric stroke


  • Cerebral autoregulation (CA) in hemispheric stroke is impaired throughout the entire affected hemisphere and occurs to a variable degree, which is influenced by the cortical perfusion (CP) level and highest in areas where tissue is hypoperfused but appears viable.

Why this matters

    CA is the ability of cerebral vasculature to achieve consistent cerebral blood flow (CBF) within physiological ranges of cerebral perfusion pressure; impaired CA can detect secondary neurological worsening. An efficient CA assessment approach may aid in preventing secondary neurological injury.
