<b><i>Introduction:</i></b> The World Health Organization predicts that the global population aged 60 years and older will double by 2050, leading to a significant rise in the public health impact of acute ischemic stroke (AIS). Existing stroke guidelines do not specify an upper age limit for the administration of intravenous thrombolysis (IVT), although some suggest a relative exclusion criterion in patients aged ≥80 in the 3–4.5-h window. Many physicians avoid treating these patients with IVT, argumenting high risk and little benefit. Our aim was to investigate the efficacy and safety of IVT treatment in patients with non-minor AIS aged ≥90, admitted to our institution. The primary efficacy endpoint was the ability to walk at discharge (mRS 0–3), and the primary safety endpoints were death and symptomatic intracranial hemorrhagic transformation (sIHT) at discharge. <b><i>Methods:</i></b> Patients with AIS aged ≥90 admitted to our center from January 2003 to December 2022 were included. They were selected if had an NIHSS ≥5, were previously ambulatory (prestroke mRS score 3 or less), and arrived within 6 h from symptom onset. Those treated or not with IVT were compared with univariate analysis. <b><i>Results:</i></b> The mean age was 93.2 (2.4) years, and 51 (73.9%) were female. The admission mRS and NIHSS were 1 (IQR 0–2) and 14 (IQR 7–22), respectively. Thrombolyzed patients had a shorter time from symptom onset to door and lower glycemia on admission. IVT was associated with a higher proportion of patients achieving mRS 0–3 at discharge (<i>p</i> = 0.03) and at 90 days (<i>p</i> = 0.04). There were no differences between groups in the risk of death (<i>p</i> = 0.55) or sIHT (<i>p</i> = 0.38). <b><i>Conclusion:</i></b> In this small sample, ambulatory patients aged ≥90 with moderate or severe AIS treated with IVT had increased odds of being able to walk independently at discharge than those not treated, without safety concerns.
