Baseline blood glucose of \\< 50mg/dL or \\>400mg/dl.\n4. Severe, sustained hypertension (SBP \\> 220 mm Hg or DBP \\> 110 mm Hg) NOTE: If the blood pressure can be successfully reduced and maintained below these levels using commonly used medications in China for these purposes (including iv antihypertensive drips), the patient can be enrolled.\n5. Patients in whom baseline NIHSS can not be obtained by a neurologist or emergency physician prior to sedation or intubation.\n6. Seizures at stroke onset which would preclude obtaining a baseline NIHSS.\n7. Serious, advanced, or terminal illness with anticipated life expectancy of less than one year.\n8. History of life threatening allergy (more than rash) to contrast medium.\n9. Patients with acute stroke within the first 48 hours after percutaneous cardiac, cerebrovascular interventions and major surgery .\n10. Renal insufficiency with creatinine ≥ 3 mg/dl.\n11. Woman of childbearing potential who is known to be pregnant or lactating or who has a positive pregnancy test on admission.\n12. Subject participating in a study involving an investigational drug or device that would impact this study.\n13. Known diagnosis or clinical suspicion of cerebral vasculitis.\n14. Patients with a pre-existing neurological or psychiatric disease that would confound the neurological or functional evaluations. This excludes patients who are severely demented, require constant assistance in a nursing home type setting or who live at home but are not fully independent in activities of daily living (toileting, dressing, eating, cooking and preparing meals, etc.).\n15. Unlikely to be available for 90 days follow-up (e.g. no fixed home address, visitor from overseas).\n16. Any other condition that, in the opinion of the investigator will pose a significant hazard to the subject if participating in the trial.\n\n Neuroimaging criteria\n17. Hypodensity with a posterior circulation Acute Stroke Prognosis Early CT score (pc-ASPECTS) \\< 6 and Pons-midbrain-index of ≥ 3 on CT angiography source images or MR with diffusion-weighted imaging or non-contrast CT.\n18.
