BACKGROUND: It remains unclear whether outcomes of patients treated with endovascular thrombectomy with large-vessel occlusion and unwitnessed onset of stroke differ from those with witnessed onset in the extended time window. METHODS: We enrolled patients with anterior circulation large-vessel occlusion (internal carotid artery, M1, or M2 segment of the middle cerebral artery) undergoing endovascular thrombectomy within 6 to 24 hours from the time last seen well, from 2014 to 2022, at 66 sites in Europe, North America, and Asia. Patients with a prestroke modified Rankin Scale score of >3 or age |
