  • Beschreibung: <jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>The utility of computed tomographic perfusion (CTP)–based patient selection for intra-arterial treatment of acute ischemic stroke has not been proven in randomized trials and requires further study in a cohort that was not selected based on CTP. Our objective was to study the relationship between CTP-derived parameters and outcome and treatment effect in patients with acute ischemic stroke because of a proximal intracranial arterial occlusion.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>We included 175 patients who underwent CTP in the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in The Netherlands (MR CLEAN). Association of CTP-derived parameters (ischemic-core volume, penumbra volume, and percentage ischemic core) with outcome was estimated with multivariable ordinal logistic regression as an adjusted odds ratio for a shift in the direction of a better outcome on the modified Rankin Scale. Interaction between CTP-derived parameters and treatment effect was determined using multivariable ordinal logistic regression. Interaction with treatment effect was also tested for mismatch (core &lt;70 mL; penumbra core &gt;1.2; penumbra core &gt;10 mL).</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p> The adjusted odds ratio for improved functional outcome for ischemic core, percentage ischemic core, and penumbra were 0.79 per 10 mL (95% confidence interval: 0.71–0.89; <jats:italic>P</jats:italic> &lt;0.001), 0.82 per 10% (95% confidence interval: 0.66–0.90; <jats:italic>P</jats:italic> =0.002), and 0.97 per 10 mL (96% confidence interval: 0.92–1.01; <jats:italic>P</jats:italic> =0.15), respectively. No significant interaction between any of the CTP-derived parameters and treatment effect was observed. We observed no significant interaction between mismatch and treatment effect. </jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>CTP seems useful for predicting functional outcome, but cannot reliably identify patients who will not benefit from intra-arterial therapy.</jats:p> </jats:sec>
