(en) [Ischemic stroke in the acute phase, review of current practical guidelines] Ischemic stroke is the first, second, and third most common cause of disability, dementia, and death, respectively. The introduction of intravenous thrombolytic treatment (IVT) and endovascular treatment (EVT) led to substantial functional prognosis improvements in patients. These treatments have radically modified the initial management of stroke. Even though the faster the better, later IVT may improve outcomes in selected patients by extending the treatment window to 9 hours after onset. These patients are selected by means of brain perfusion imaging. According to perfusion parameters, patients can be eligible for EVT until 24 hours after symptoms onset. At the same time, indications for IVT have been expanded and contraindications reduced. More patients can see their prognosis improved.
