Abstract Number: Esoc2026a217 Hypoperfusion Intensity Ratio May Not Be a Good Predictor of Functional Outcome in Anterior Circulation Large Vessel Occlusion Stroke When Adjusting for Multiple Covariates
Retrospective analysis examines the predictive value of hypoperfusion ratio in anterior circulation large vessel occlusion stroke, suggesting alternative predictors.
Key Points
This study aims to evaluate the predictive ability of hypoperfusion intensity ratio for functional outcomes in large vessel occlusion stroke while adjusting for covariates.
Single center retrospective study analyzing clinical data from electronic medical records.
Multivariate logistic regression was performed on 83 patients to assess the association of hypoperfusion intensity ratio with 90-day mRS outcomes.
Comparison of variables using Mann-Whitney U, Chi-squared, and independent t-tests.
Of the 83 records analyzed, 65% underwent endovascular therapy (EVT), with 49% achieving a modified Rankin Scale (mRS) score of ≤2 at 90 days.
Good functional outcomes correlated with lower prior stroke rates (7.3% vs. 3.8%, p=0.039) and higher ASPECTS scores (median 8 vs. 7, p=0.004).
Higher Tmax > 6s was identified as a predictor of 90-day functional independence (OR 1.03; p=0.026).
