Summary

A multicenter, prospective, open-label, blinded-endpoint, randomized controlled trial to assess the effectiveness and safety of catheter-based focal intracranial hypothermia combined with endovascular reperfusion therapy for acute patients with a Large Core Infarction.

Conditions

Interventions

OTHER

intra-arterial local therapeutic hypothermia

In the treatment group, after crossing the occluded vessel segment with a microcatheter and confirming its location in the true lumen, 4℃-saline will be extracted from the refrigerator. 50ml will be drawn within 2 minutes and then continuously infused at a rate of 10ml/min using an infusion pump. After infusion, standard thrombectomy procedures will be performed. After completion of the thrombectomy procedure (regardless of achieving 2b/3-grade reperfusion), another 300ml of saline will be extracted within 2 minutes and infused at a rate of 30ml/min for 10 minutes through the intermediate catheter or guiding catheter placed in the internal carotid artery. Post-infusion, contrast-enhanced cerebral angiography using room temperature contrast agent is generally not recommended to dilute the local temperature.

OTHER

Control (Normal saline)

In the contral group, after crossing the occluded vessel segment with a microcatheter and confirming its location in the true lumen, roomtemperature saline will be extracted from the refrigerator. 50ml will be drawn within 2 minutes and then continuously infused at a rate of 10ml/min using an infusion pump. After infusion, standard thrombectomy procedures will be performed. After completion of the thrombectomy procedure (regardless of achieving 2b/3-grade reperfusion), another roomtemperature 300ml of saline will be extracted within 2 minutes and infused at a rate of 30ml/min for 10 minutes through the intermediate catheter or guiding catheter placed in the internal carotid artery.
