BACKGROUND AND PURPOSE: Stroke is a leading cause of morbidity and mortality worldwide. Endovascular therapy (EVT) has been established as a gold standard option to treat acute ischemic stroke (AIS) patients with large vessel occlusion (LVO) presenting within 6 h of symptom onset. However, there is a paucity of information regarding patient outcome and mortality in patients presenting in late time window within 6 to 24 h. In this study, we aimed to assess for predictors of outcomes in late window stroke patients following EVT. METHODS: We analyzed data from 202 patients treated with EVT from four comprehensive stroke centers. All patients were above 18 years of age and had symptoms onset of 6-24 h. mRS of 0-2 after three months was defined as favorable outcome. RESULTS: Patients with favorable outcome had lower median age ( 0.003), lower pre-EVT National Institute of Health Stroke Scale (NIHSS) score ( 0.000), lower diabetes mellitus ( 0.041), stroke history ( 0.041), parenchymal hematoma (PH) ( 0.000) and fewer attempts to achieve successful recanalization ( 0.001). Multivariate regression analysis found age ( 0.007), diabetes mellitus ( 0.022), successful recanalization (mTICI≥2b) ( 0.006), NIHSS at onset ( 0.000), and PH1 + PH2 Heidelberg bleeding classification ( 0.009) as predictors of functional outcome. CONCLUSION: Age, diabetes mellitus history, baseline NIHSS score, successful recanalization, and PH are predictors of 90-day functional outcome of late-window ischemic stroke patients undergoing EVT.
