Age ≥18 years;

Patients presenting with posterior circulation ischemic stroke symptoms due to BAO;

BAO confirmed by computed tomographic angiography (CTA)/ magnetic resonance angiography (MRA);

Time from AIS symptom onset to randomization within 4.5-24 hours, stroke onset is defined as the onset of acute symptoms leading to the clinical diagnosis of basilar artery occlusion (BAO) not considering the time of any preceding minor prodromal symptoms (such as isolated vertigo, diplopia or sensory changes) as onset time or, if not known, the time the patient was last known to be well (including wake-up stroke and unwitnessed stroke);
