Background and Purpose- We investigated whether subarachnoid extension (SAHE) of intracerebral hemorrhage (ICH) is associated with hematoma expansion (HE). Methods- Retrospective analysis of patients with primary spontaneous ICH admitted at 3 academic hospitals in Italy. The study population was divided into a development and a replication cohort. ⋯ Conclusions- SAHE predicts HE in lobar ICH. This may improve the stratification of HE risk in clinical practice or future trials targeting HE. Further research is needed to confirm our findings and characterize the underlying biological mechanisms.

Background and Purpose- Reversal of dabigatran before intravenous thrombolysis in patients with acute ischemic stroke has been well described using alteplase but experience with intravenous tenecteplase is limited. Tenecteplase seems at least noninferior to alteplase in patients with intracranial large vessel occlusion. We report on the experience of dabigatran reversal before tenecteplase thrombolysis for acute ischemic stroke. ⋯ Two deaths occurred from large territory infarction. Conclusions- Our experience suggests intravenous thrombolysis with tenecteplase following dabigatran reversal using idarucizumab may be safe in selected patients with acute ischemic stroke. Further studies are required to more precisely estimate the efficacy and risk of clinically significant hemorrhage.
