队列研究 

Study design:

Cohort study 

研究目的:

①寻找血液学及影像学标志物,筛选可超时间窗行血管再通治疗的患者,扩大受益人群; ②寻找可预测再灌注损伤、出血转化、恶性水肿、血管再闭塞的特异性生物标志物,早期进行个体化干预,增加再通治疗效果,降低患者致残、致死率。  

Objectives of Study:

①Looking for hematology and imaging markers, screening patients who can be treated with recanalization treatment beyond the time window, and expanding the beneficiary population; ②Looking for specific biomarkers that can predict reperfusion injury, hemorrhagic transformation, malignant edema, and vessel reocclusion, early carrying out individualized interventions to increase the effectiveness of recanalization treatment, thus reducing the rate of disability and lethality of patients.

Patients of intravenous thrombolysis bridging treatment with mechanical thrombectomy: If the symptoms do not improve significantly after intravenous thrombolysis, patients who meet the above mechanical thrombectomy indications should undergo bridging treatment.
