Outcomes
Stroke, hematoma, cerebral infarction, intracerebral hemorrhage
STROKE, HEMATOMA, CEREBRAL INFARCTION, INTRACEREBRAL HEMORRHAGE
The primary outcome was the effect of AI-enabled LVO detection on DTG time. Secondary outcomes included time from hospital arrival to IV tPA bolus in eligible patients, time from initiation of initial noncontrast head CT scan to start of EVT, hospital length of stay, and rates of substantial reperfusion after EVT (thrombolysis in cerebral infarction score of 2b/3). As noted above, CTA was performed immediately after initial noncontrast head CT in all patients. Safety outcomes included the rate of mortality, any intracerebral hemorrhage following EVT, and rates of symptomatic intracerebral hemorrhage, which were defined as parenchymal hematoma type 2 with associated worsening of 4 points or more on the National Institutes of Health Stroke Scale (NIHSS).
