Takeaway

  • A high number of cerebral microbleeds (CMBs) on MRI is associated with symptomatic intracerebral hemorrhage (sICH) in patients with stroke treated with intravenous thrombolysis (IVT).

Why this matters

  • sICH is common after IVT, but hard to predict.  

Key results

  • sICH rates were similar in patients with and without CMBs (5.8% vs 3.5%; P=.27).
  • Inhospital mortality rates were similar in patients with and without CMBs (6.8% vs 5.6%; P=.65).
  • sICH rates were significantly higher in patients with 10 CMBs (30%; P<.001).
  • The presence of 10 CM...
