Patients with M1 or M2 occlusions and low ASPECTS (&lt;6) who underwent successful EVT (modified treatment in cerebral ischemia score of 2b or higher) were included. Primary outcome was futile EVT reperfusion (defined as 90-day modified Rankin scale of 5 or 6). Other outcomes of interest include acceptable outcomes (modified Rankin scale of 3 or less) and intracranial hemorrhage (ICH), and all-cause 90-day mortality. Outcomes for M1 patients were compared to M2 patients with multivariable logistic regression models accounting for potential confounders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>173 patients with M1 or M2 occlusions and low ASPECTS (&lt;6) who underwent successful EVT were identified. After multivariable adjustments, M2 patients had significantly higher odds of futile reperfusion (OR 5.48 [95%CI 1.91 to 15.7], p\u2009=\u20090.002), lower odds of acceptable outcomes (OR 0.33 [95%CI 0.12 to 0.89], p\u2009=\u20090.028), and higher odds of all-cause mortality (OR 4.90 [95%CI 1.65 to 14.5], p\u2009=\u20090.004). These findings suggest that EVT's efficacy for low-ASPECTS stroke patients may be diminished for patients with M2 occlusions.
