We aimed to verify the ability of the collateral map to predict futile EVT in patients with acute anterior circulation ischemic stroke.Methods : This secondary analysis of a prospective observational study included data from participants underwent EVT for acute ischemic stroke due to occlusion of the internal carotid artery and\/or the middle cerebral artery within 8 hours of symptom onset. Multiple logistic regression analyses were conducted to identify independent predictors of futile recanalization (modified Rankin scale score at 90 days of 4\u20136 despite of successful reperfusion).Results : In a total of 214 participants, older age (odds ratio [OR], 2.40; 95% confidence interval [CI], 1.56 to 3.67; &lt;i&gt;p&lt;\/i&gt;&lt;0.001), higher baseline National Institutes of Health Stroke Scale (NIHSS) scores (OR, 1.12; 95% CI, 1.04 to 1.21; &lt;i&gt;p&lt;\/i&gt;=0.004), very poor collateral perfusion grade (OR, 35.09; 95% CI, 3.50 to 351.33; &lt;i&gt;p&lt;\/i&gt;=0.002), longer door-to-puncture time (OR, 1.08; 95% CI, 1.02 to 1.14; &lt;i&gt;p&lt;\/i&gt;=0.009), and failed reperfusion (OR, 3.73; 95% CI, 1.30 to 10.76; &lt;i&gt;p&lt;\/i&gt;=0.015) were associated with unfavorable functional outcomes. In 184 participants who achieved successful reperfusion, older age (OR, 2.30; 95% CI, 1.44 to 3.67; &lt;i&gt;p&lt;\/i&gt;&lt;0.001), higher baseline NIHSS scores (OR, 1.12; 95% CI, 1.03 to 1.22; &lt;i&gt;p&lt;\/i&gt;=0.006), very poor collateral perfusion grade (OR, 4.96; 95% CI, 1.42 to 17.37; &lt;i&gt;p&lt;\/i&gt;=0.012), and longer door-to-reperfusion time (OR, 1.09; 95% CI, 1.03 to 1.15; &lt;i&gt;p&lt;\/i&gt;=0.003) were associated with unfavorable functional outcomes.Conclusion : The assessment of collateral perfusion status using the collateral map can predict futile EVT, which may help select ineligible patients for EVT, thereby potentially reducing the rate of futile EVT.<\/jats:p>","DOI":"10.3340\/jkns.2023.0139","type":"journal-article","created":{"date-parts":[[2023,8,4]],"date-time":"2023-08-04T00:15:17Z","timestamp":1691108117000},"page":"31-41","update-policy":"https:\/\/doi.org\/10.3340\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Impact
