干预措施:

Interventions:

组别:

联合治疗组

样本量:

157

Group:

combining treatment group

Sample size:

干预措施:

将4℃生理盐水以15ml/min于微导管中灌注,持续灌注5min。之后,进行血管开通(机械取栓、抽吸血栓、球囊成形、支架置入等)开放血流,血管再通结束后,于中间导管或指引导管或长鞘中以22ml/min灌注4℃生理盐水,持续灌注10min,间隔10min后,再继续灌注4℃生理盐水10min。直肠监测体温变化。

干预措施代码:

Intervention:

Normal saline at 4℃ was injected into a microcatheter at 15ml/min for 5min. After that, vascular opening (mechanical thrombectomy, thrombectomy, balloon forming, stent insertion, etc.) was performed to open blood flow. After vascular recanalization, 4℃ normal saline was injected into the intermediate catheter or guide catheter or long sheath at 22ml/min for 10 minutes, and then 4℃ normal saline was continued for 10 minutes after an interval of 10 minutes. Rectal temperature changes were monitored.

Intervention code:

组别:

单纯血管内介入治疗组

样本量:

157

Group:

Endovascular interventional therapy alone group

Sample size:

干预措施:

常规进行血管开通(机械取栓、抽吸血栓、球囊成形、支架置入等),不进行低温盐水灌注。

干预措施代码:

Intervention:

Vascular opening (mechanical thrombectomy, thrombus extraction, balloon forming, stent placement, etc.) was performed routinely, without cryogenic saline perfusion.
