• Age ≥ 18 years old;
• Within 4-24 hours after intravenous thrombolytic therapy with tenerplase for acute ischemic stroke, there was no significant change in symptoms compared to the baseline (defined as an increase or decrease of 0 or 1 point in the NIHSS score), and neurological function deteriorated (defined as an increase of ≥ 2 in the NIHSS score compared to the baseline) Fluctuations in neurological function (defined as an increase of 4 points or more in the NIHSS score compared to the baseline and then a decrease of 4 points or more);
• NIHSS ≥ 4 points before randomization;
• The patient or their family members sign a written informed consent form.
