Hypothermia has been confirmed and widely applied in the treatment of coma patients after resuscitation from cardiac arrest, but its effect on the prognosis of patients with AIS is still controversial. Previous basic research has confirmed that hypothermia can significantly reduce the infarct volume and improve the survival rate and behavioral defects of mice by protecting ischemic brain tissue and improving reperfusion injury through a variety of ways. Therefore, we hypothesized that hypothermia can improve the prognosis of patients with AIS after reperfusion by improving reperfusion injury. This is a phase II clinical trial to to verify the efficacy and safety of endovascular hypothermia in these patients,This study enrolled patients with massive cerebral infarction after endovascular treatment recanalization, patients are divided into study group and control group. The study group received endovascular hypothermia for 12 hours following endovascular treatment and recanalization, and the control group received only usual medical treatment following endovascular treatment and recanalization. We will preliminarily explore the mechanism of endovascular hypothermia in successful reperfusion of large vessel occlusion AIS, and to provide reference for the design of future clinical trials.
The primary objective of this study is to determine the feasibility and safety of receiving intravascular hypothermia treatment for patients experiencing endovascular treatment after acute ischemic stroke(AIS) due to a large vessel occlusion.
