Eligibility
Inclusion criteria
Inclusion criteria: 1. Aged >= 18 years; 2. No gender restriction; 3. Definite diagnosis of acute ischemic stroke, with imaging confirmation of intracranial anterior circulation large vessel occlusion (intracranial segment of the internal carotid artery or M1 segment of the middle cerebral artery) as the culprit vessel; 4. Time from symptom onset to hospital arrival = 6. 6. Preoperative Alberta Stroke Program Early CT Score (ASPECTS) > 5. 7. The subject or their legally authorized representative agrees to participate in the study and signs the informed consent form.
Exclusion criteria
Exclusion criteria: 1. Preoperative MRA or CTA confirms moderate-to-severe atherosclerotic stenosis (stenosis rate >= 50%) in the ipsilateral/contralateral carotid artery or proximal intracranial culprit artery. 2. Preoperative imaging (NCCT or MRI) indicates any type of intracranial hemorrhage on the ipsilateral side, including but not limited to parenchymal hemorrhage, subarachnoid hemorrhage (SAH), or subdural/epidural hematoma. 3. History of severe intracerebral hemorrhage, epilepsy, or active brain tumor. 4. Extensive skull defect, deformity, or severe injury to the scalp skin that prevents sensor placement. 5. History of prior cerebral infarction in the contralateral hemisphere. 6. Use of medications or treatments that may affect cerebral perfusion and cerebral oxygen saturation. 7. Presence of severe anemia upon admission, defined as hemoglobin (Hb) < 90 g/L (or < 9 g/dL). 8. Severe pulmonary disease, severe cardiac dysfunction, hepatic or renal insufficiency, severe infection, advanced malignancy, or other conditions with a life expectancy < 3 months. 9. Pregnant or breastfeeding women.
