Ischemic Stroke, Neuroprotection
Conditions
Brief summary
To explore the safety and feasibility of intra-arterial neuroprotective strategy in acute ischemic stroke patients who missed recanalization operation.
Interventions
Intra-arterial administration of 3-n-butylphthalide for 24 hours via microcatheter at 17.36 ug/min.
