Eligibility
Inclusion criteria
Inclusion criteria: 1) Age =35 years and =80 years, regardless of gender; 2) Diagnosis of acute ischemic stroke within 24 hours of onset (onset to completion of reperfusion therapy); 3) First stroke or before stroke onset (mRS 0-1 points); 4) Image-confirmed acute intracranial large vessel occlusion (LVO), including occlusion of the intracranial segment of the internal carotid artery, the T-bifurcation, the middle cerebral artery M1 and/or M2 segments, and the anterior cerebral artery A1 and/or A2 segments; 5) ASPECTS = 6; 6) National Institutes of Health Stroke Scale (NIHSS) score: 6 < NIHSS = 25 after the onset of the event; 7) Patients who meet the indications for reperfusion therapy, including mechanical thrombolysis, bridging therapy (thrombolysis with intravenous r-tPA), etc., and for whom mechanical thrombolysis is planned; 8) Patients or their legal representatives voluntarily signed an informed consent approved by the Ethics Committee.
Exclusion criteria
Exclusion criteria: 1) Severe impairment of consciousness: =2 on the NIHSS 1a level of consciousness; 2) a previous history of definite intracranial hemorrhagic disease: including parenchymal hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage, and subdural/extracranial hematoma 3) intracranial tumors, intracranial arteriovenous malformations or aneurysms; 4) bilateral anterior or posterior circulation ischemic stroke; 5) large vessel occlusion of rare or unknown etiology: e.g., entrapment, vasculitis, etc; 6) Fiber-lowering therapy such as dual antiplatelet agents, tirofiban, warfarin, new oral anticoagulants, argatroban, snake venom, defibrinolytic enzymes, and earthworm kinase after the onset of the disease; 7) Severe hepatic insufficiency or renal insufficiency and those receiving dialysis for various reasons prior to randomization (severe hepatic insufficiency is defined as an ALT value >3 times the upper limit of normal or an AST value >3 times the upper limit of normal; severe renal insufficiency is defined as a blood creatinine of >3.0 mg/dl (265.2 µmol/L)) or a creatinine clearance of 180 mmHg or diastolic blood pressure >110 mmHg) that is difficult to control with medications; 10) History of significant head trauma or stroke within 3 months prior to randomization; 11) intracranial or intraspinal surgery within 3 months prior to randomization; 12) history of major surgery or severe physical trauma within 1 month prior to randomization; 13) immediate known hemorrhagic retinopathy; 14) male subjects (or their partners) or female subjects who plan to have children throughout the trial and within 3 months of study completion or subjects who are unwilling to use one or more non-pharmacological contraceptive methods (e.g., total abstinence, condoms, ligation, etc.) during the trial; 15) Those with known contraindications to contrast agents or other contrast agents, cilostazol, dexamethasone allergy; 16) other surgical or interventional procedures planned within 3 months that may require termination of the trial drug; 17) Advanced stage of any disease with a life expectancy of <6 months; 18) Patients who have received an experimental drug or instrument within 3 months; 19) Other conditions that make participation in this clinical study inappropriate, such as inability to understand and/or comply with study procedures and/or follow-up visits due to psychiatric disorders, cognitive or mood disorders, or contraindications to thrombolysis, nuclear magnetic resonance imaging, or other conditions that, in the opinion of the investigator, may affect compliance or make participation in this study inappropriate.
