When it is more than 6h but less than 24h (inclusive) from the onset of stroke to the completion of femoral artery puncture, brain CT or MR should be performed and Aspects ≥6 points should be satisfied.(If immediate CT perfusion imaging or MR perfusion imaging is feasible, CTP or MRP is recommended to assist in the assessment of the infarct core, and Aspects ≥6 points shall also be satisfied);\n3. DSA angiography showed acute intracranial arterial occlusion, including intracranial segment of internal carotid artery (C4-C7), middle cerebral artery (M1/M2), basilar artery and intracranial segment of vertebral artery (V4).\n\nGeneral exclusion criteria：\n\n1. Neither MRI nor CT can be performed;\n2. Hemorrhagic stroke or major ischemic stroke within 6 months before enrollment;\n3. Severe persistent hypertension that cannot be controlled by venous hypotension, i.e., patients with SBP persistent \\>185mmHg and/or DBP persistent \\>110mmHg;\n4.
