  1. Two patients developed minor secondary infarction (one partial left MCA and one partial right ACA territory). One patient with primary large right temporal ICH developed territorial infarctions in both MCA territories in the course of treatment. Two patients died, one from rebleeding from an endovascularly occluded aneurysm outside of study procedures and one due to extended infarction in both MCA territories.
  2. ICH intracerebral hemorrhage, IVH intraventricular hemorrhage, ICA internal carotid artery, MCA middle cerebral artery, Acom anterior communicating artery, GOS Glasgow Outcome Scale.
