Endovascular treatment in patients with acute ischemic stroke presenting beyond 6 h after symptom onset: An international multicenter cohort study of the EVA-TRISP collaboration

After positive findings in clinical trials the time window for endovascular thrombectomy (EVT) for patients with an acute ischemic stroke has been expanded up to 24 h from symptom onset or last seen well (LSW). We aimed to compare EVT patients' characteristics and outcomes in the early versus extended time window and to compare outcomes with the DAWN and DEFUSE 3 trial results.
