Prevalence of fast and slow infarct growth within 24 hours of stroke onset


  • Fast ischemic core volume (ICV) growth was identified in 25% of patients with imaging 0–6 h after onset of acute anterior circulation large vessel occlusion (ACLVO).

Why this matters

  • Better knowledge of the distribution of rapid and slow ICV growth after ACLVO onset may impact policies on triage and referral for reperfusion therapy.
