Abstract
Objective: To compare outcomes of patients submitted to endovascular treatment (EVT) presenting within 6 hours or 6 - 24 hours, selected using simple imaging protocol. Subject and method: A prospective study was performed, which included consecutive patients with anterior circulation ischemic stroke eligible for EVT within 6 hours or 6 - 24 hours between November, 2017 and July, 2019. Result: Of the 184 patients were included, 107 (58.2%) received acute treatment in early window. Baseline characteristics were similar between groups, except for longer onset to groin puncture time (300 vs 705 minute; p<0.0001), higher NIHSS (13 vs 16, p<0.0001), lower in ASPECTS (9 vs 8; p<0.0001), in the late window group. No significant differences in successful reperfusion rate and rates of parenchymal hematoma type 2 (81.3% vs 83.1%, p=0.75, 4/107 vs 4/77, p=0.63, respectively). Functional independence (mRS 0-2) and mortality at 90 days did not differ significantly (65.4% vs 57.1%, p=0.25, 10.3% vs 6.5%, p=0.43, respectively). Conclusion: This observational study suggests that EVT may be safe and feasible in patients presenting within 6 - 24 hours selected using clinical-core mismatch and collateral blood blow.
