Outcomes of endovascular thrombectomy in patients selected by computed tomography perfusion imaging - a matched cohort study comparing nonagenarians to younger patients.

Background: Endovascular thrombectomy (EVT) is efficacious for appropriately selected patients with large vessel occlusions (LVO) up to 24 hours from symptom onset. There is limited information on outcomes of nonagenarians, selected with computed tomography perfusion (CTP) imaging.

Methods: We retrospectively analyzed data from a large academic hospital between December 2017 and October 2019.
