TL;DR: In patients with acute stroke with an unknown time of onset, intravenous alteplase guided by a mismatch between diffusion‐weighted imaging and FLAIR in the region of ischemia resulted in a significantly better functional outcome and numerically more intracranial hemorrhages than placebo at 90 days.
Journal ArticleDOI
European Stroke Organisation (ESO) guidelines on intravenous thrombolysis for acute ischaemic stroke.

TL;DR: The European Stroke Organisation (ESO) guidelines provide evidence-based recurrence guidelines for patients with acute ischaemic stroke as mentioned in this paper, where intrvenous thrombolysis is the only approved systemic reperfusion treatment.
Journal ArticleDOI
Design and Validation of a Prehospital Stroke Scale to Predict Large Arterial Occlusion The Rapid Arterial Occlusion Evaluation Scale
Natalia Pérez de la Ossa,David Carrera,Montse Gorchs,Marisol Querol,Mónica Millán,Meritxell Gomis,Laura Dorado,Elena López-Cancio,María Hernández-Pérez,Vicente Chicharro,Xavier Escalada,Xavier Jiménez,Antoni Dávalos +12 more
TL;DR: The RACE scale is a simple tool that can accurately assess stroke severity and identify patients with acute stroke with large artery occlusion at prehospital setting by medical emergency technicians.
Journal ArticleDOI
Mechanical Thrombectomy With the Solitaire AB Device in Large Artery Occlusions of the Anterior Circulation A Pilot Study
Carlos Castaño,Laura Dorado,C. Guerrero,Mónica Millán,Meritxell Gomis,Natalia Pérez de la Ossa,Mar Castellanos,M. Rosa García,Sira Domenech,Antoni Dávalos +9 more
TL;DR: The results suggest that the Solitaire AB device can rapidly, safely, and effectively retrieve clots from the middle cerebral artery and terminus internal carotid artery within 8 hours from symptoms onset.
Journal ArticleDOI

TL;DR: Better outcomes after endovascular thrombectomy were associated with GA, after adjustment for baseline prognostic variables, indicating that treatment should not be withheld in those who require anaesthesia for medical reasons.
