Eligibility:

All Genders

18-80 years

Phase:

Brief Summary

This is a multicenter, randomized, controlled, subject- and assessor-blinded clinical trial. The research objective is to evaluate the safety and efficacy of selective intra-arterial cooling infusion ...

Detailed Description

Acute ischemic stroke (AIS) is the leading cause of death and disability in China. Randomized trials involving patients with acute stroke due to large-artery occlusion in the anterior circulation have...

Eligibility Criteria

Inclusion

  • Inclusion Criteria
  • Age ≥ 18 and ≤ 80.
  • Clinical signs consistent with acute ischemic stroke with large vessel occlusion in the anterior circulation (intracranial segment of the internal carotid artery, middle cerebral artery M1 segment) demonstrated with CTA/MRA/DSA.
  • NIHSS score obtained prior to randomization ≥ 6 and ≤ 25.
  • Modified Rankin Scale ≤ 1 prior to qualifying stroke.
  • Arterial puncture performed within 24 hours from symptom onset or LKW.
  • For the patients with symptom onset within 6 hours, the ASPECT score ≥ 6; for the patients with onset within 6-24 hours, the therapy should meet the imaging criteria of DAWN or DEFUSE-3 trial.
  • Patient/Legally Authorized Representative has signed the Informed Consent Form.
  • Exclusion Criteria
  • Baseline CT/MRI confirms the presence of multiple vascular territory acute strokes.
  • Baseline CT/MRI confirms the presence of arterial dissection.
  • Evidence of intracranial hemorrhage or hemorrhagic transformation before thrombectomy.
  • Known allergies or intolerances to antiplatelet agents, anticoagulation drugs, iodinated contrast and/or anesthetics.
  • Severe infection (e.g. sepsis) or multiple organ failure.
  • Known hereditary or acquired hemorrhagic diathesis, coagulation factor deficiency; recent oral anticoagulant therapy with INR \> 3. Patients on factor Xa inhibitor for 48 hours ago must have a normal APTT.
  • Baseline platelet count \< 50 × 10\^9/L.
  • Blood glucose concentration\<50 mg/dL (2.7 mmol/L) or \>400 mg/dL (22.2 mmol/L).
  • Refractory hypertension that is difficult to control by medication (Defined as persistent systolic blood pressure\>185 mmHg or diastolic blood pressure\>110 mmHg).
  • Previous NHYA\>1.
  • Untreated moderate or severe coronary artery stenosis, or previous coronary artery bypass surgery.
  • Undergoing hemodialysis or peritoneal dialysis; known severe renal insufficiency with glomerular filtration rate \< 30 mL/min or serum creatinine \>220 mmol/L (2.5 mg/dL).
  • Known intracranial aneurysm, and cerebral arteriovenous malformation.
  • Malignant brain tumor or CNS infection.
  • Pre-existing neurological or psychiatric disease that would confound the neurological or functional evaluations (e.g., dementia or mental illness)
  • Female who is pregnant or lactating at time of admission.
  • Anticipated life expectancy \< 6 months.
  • Current participation in another investigational drug or device study.
  • For other reasons, the responsible clinicians believe that the patient is not suitable for continued treatment.
