Biomarkers to Predict Hemorrhage and Outcomes After Endovascular Treatment in Patients With Acute Large Vessel Occlusion

The main aim of the biomarkers to predict Hemorrhagic transformation(HT) after endovascular treatment in Acute Ischemic Stroke Patients. The study has three main parts. During the first part, the investigators propose to conduct an enrollment of patients after thrombectomy in acute Ischemic Stroke and healthy controls. Serum biomarkers levels were analyzed (before and after) endovascular treatment patients and controls respectively. During the second part, HT was evaluated and classified on cranial computed tomography and/or MRI post- treatment and was considered as symptomatic HT (sHT) if associated with neurological deterioration. During the third part, the investigators aim to demonstrate the level of biomarkers can significant predict HT and outcomes in stroke patients undergoing revascularization.
