Hypoperfusion Intensity Ratio Predicts Successful Recanalization in M2 Middle Cerebral Artery Occlusion Stroke Treated with Thrombectomy

This retrospective study suggests that HIR may serve as a predictor of success in EVT and a potentially useful adjunct tool for decision-making in MeVO stroke patients. However, the limited sample size and unmeasured cofounders should be considered. These findings underscore the role that perfusion imaging-based quantitative collateral assessments can play in prognosis for these patients.

Abstract

This retrospective study suggests that HIR may serve as a predictor of success in EVT and a potentially useful adjunct tool for decision-making in MeVO stroke patients. However, the limited sample size and unmeasured cofounders should be considered. These findings underscore the role that perfusion imaging-based quantitative collateral assessments can play in prognosis for these patients.
