A novel clinical and imaging based score for predicting outcome prior to endovascular treatment of acute ischemic stroke

Society of NeuroInterventional Surgery: 11/10/12

Introduction Outcome after stroke intervention remains disappointing, with only 30–50% of patients having a good outcome at 90 days. We sought to identify important outcome prognosticators.

Methods All consecutive patients that presented with an acute anterior circulation ischemic stroke, with adequate CT perfusion imaging, and that underwent emergency endovascular treatment at two centers between January 1, 2009 and November 2011, were retrospectively reviewed. Investigators estimated the percentage of the total ischemic tissue that had decreased cerebral blood volume (CBV) compared with the total area with elevated time to peak (the penumbra). Multivariate regression analyses were performed to identify variables with prognostic significance and a scoring system was created. Read more
