Exclusion criteria:

1. Baseline systolic blood pressure >185 mmHg or diastolic blood pressure >110 mmHg.
2. Baseline blood glucose <2.7 mmol/L or >22.2 mmol/L.
3. Evidence of intracranial hemorrhage on pre-mechanical thrombectomy CT or MRI.
4. Confirmed or suspected cerebral vasculitis/fibromuscular dysplasia/dissection.
5. Operator judges that the interventional devices used in the study cannot reach the target site.
6. Stent placement in the middle cerebral artery during the thrombectomy procedure.
7. Requirement for >2 local balloon dilatations for angioplasty.
8. Contraindications to head MRI.
9. Occluded vessel combined with tandem extracranial stenosis or occlusion.
10. Number of thrombectomy attempts >3.
11. Space-occupying effect or intracranial tumor confirmed by CT or MRI.
