Brief Summary
This study aims to conduct a prospective, randomized, double-blind, multicenter, parallel-controlled, group-sequential trialto scientifically evaluate the safety and efficacy of remote ischemic preconditioning (RIC) in preventing early neurological deterioration (END) in patients with acute perforating artery infarction (PAI).

Outcome Measures
Primary Outcomes (1)
The incidence of early neurological deterioration
an increase of ≥2 points in the National Institutes of Health Stroke Scale (NIHSS), including an increase of ≥1 point in the motor score. NIHSS is a stroke severity score composed of 11 items (range from 0 to 42, higher values indicate more severe deficits).
5 days after randomization
Secondary Outcomes (7)
The incidence of early neurological deterioration
2 days after randomization
Proportion of patients with a modified Rankin Scale score of 0-1
90 days after randomization
The incidence of early neurological improvement
5 days after randomization

Other Outcomes (4)

within 90 days from randomization
The incidence of mortality
within 90 days from randomization

Study Arms (2)
RIC group
EXPERIMENTALThe standard RIC procedure involves placing a blood pressure cuff on both upper limbs, rapidly inflating the cuff to occlude arterial blood flow and induce transient limb ischemia, followed by deflating the cuff to restore blood perfusion. RIC is administered twice daily on both upper limbs, with each session consisting of 5 cycles, for 5-7 consecutive days. The inflation pressure for RIC treatment is set at 200 mmHg.

SHAM COMPARATORThe standard RIC procedure involves placing a blood pressure cuff on both upper limbs, rapidly inflating the cuff to occlude arterial blood flow and induce transient limb ischemia, followed by deflating the cuff to restore blood perfusion. RIC is administered twice daily on both upper limbs, with each session consisting of 5 cycles, for 5-7 consecutive days. The inflation pressure for RIC treatment is set at 60 mmHg.

Eligibility Criteria
You may qualify if:
- Age 18 years or older;
- Diagnosed with acute ischemic stroke;
- Clinical symptoms consistent with perforating artery infarction (NIHSS score ≤5, with consciousness item 1a ≤1);
- Time from onset to randomization within 48 hours;
- Diffusion-weighted imaging (DWI) showing a single infarct in the perforating artery territory with a maximum diameter ≤30 mm, meeting at least one of the following:
- (1) Diameter ≤15 mm and involving two or more axial slices; (2) Maximum diameter ≥15 mm; (3) Connected to the ventral surface of the pons but not crossing the midline; 6) Stenosis of parent artery \<70%; 7) Signed informed consent obtained from the patient or their legally authorized representative.

- Uncontrolled severe hypertension (systolic blood pressure \[BP\] ≥180 mmHg or diastolic BP ≥110 mmHg);
- Severe hepatic or renal dysfunction (Alanine Aminotransferase or Aspartate Aminotransferase \> 3 × upper limit of normal; creatine kinase \>3 × upper limit of normal; estimated Glomerular Filtration Rate \< 30 mL / min / 1.73 m²);
- Patients with thrombocytopenic purpura, coagulation disorders, or active visceral bleeding;
- Patients in the acute phase of fundus hemorrhage;
- History of severe aphasia or psychiatric disorders affecting clinical assessment;
- Life expectancy \<90 days;
