Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CA-guided BP
The upper and lower limits of autoregulation determined by ICM+ software are used to guide the range of blood pressure control, but no more than 40% above or below the usual BP. From when the upper or lower limit of autoregulation appeared in ICM+ software to 48h after revascularization, the total time of actual BP beyond the CA range will be no more than two hours through drug intervention.
Hypotensive Drugs and/or Vasoactive Drugs
To manipulate the blood pressure within a certain range with hypotensive drugs (e.g. nifedipine, benidipine, captopril, benazepril, irbesartan, labetalol, urapidil) and/or vasoactive drugs (noradrenaline or dopamine).
Fixed target BP
After randomization to 48h after endovascular therapy, the target of BP was determined by clinicians according to current guidelines, i.e. \<180/105mmHg.
Hypotensive Drugs and/or Vasoactive Drugs
To manipulate the blood pressure within a certain range with hypotensive drugs (e.g. nifedipine, benidipine, captopril, benazepril, irbesartan, labetalol, urapidil) and/or vasoactive drugs (noradrenaline or dopamine).

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* No functional disability before stroke (mRS 0-1)

* Informed consent is given by the patient or the legal representative.
Exclusion Criteria
* Coma, dilated pupils on one or both sides, dull or absent light reflex is noticed before randomization
* Dissection of aorta, common carotid artery, internal carotid artery, subclavian artery, intracranial artery; severe bilateral subclavian artery stenosis; contraindications of radial artery puncture were found before or during surgery.
* Shock.
* Severe cardiomyopathy with heart failure (EGFR ≤ 30% or NYHA Grade IV), acute myocardial infarction, or unstable angina.
* Possible infective endocarditis, infective embolism, or vasculitis.
* Participating in other clinical research involving drug or device intervention after endovascular therapy.
* Women who plan or are pregnant, or breastfeeding.
* Severe liver or kidney disease, malignant tumor with a life expectancy is less than 3 months.
* The 90-day follow-up is not expected to be completed.
