The current standard of care to treat acute stroke patients presenting within 4.5 hours of stroke symptom onset is intravenous (IV) Alteplase.1 Over the past decade, tremendous efforts have been made to challenge the conventional window of 4.5 hours for the administration of Alteplase to expand the patient population which can benefit from thrombolysis. Based on the recent meta-analysis, 2 we have strong evidence supporting the use of IV thrombolysis in patients presenting between 4.5 to 9 hours of symptom onset with favorable perfusion imaging and it appears that the era of the conventional 4.5 hours window may be coming to an end"
