The association between perihematomal cerebral blood volume and intracerebral hemorrhage expansion

Takeaway

  • Reduced cerebral blood volume (CBV) in the area surrounding an intracerebral hemorrhage (ICH) may promote hematoma expansion.

Why this matters

  • Hematoma expansion is a common event during acute ICH and is associated with an unfavorable prognosis; however, the role of the brain parenchyma surrounding the hemorrhage is unclear.
