Neutrophil Extracellular Traps Formation

Eligibility:

All Genders

18+ years

Phase:

NA

Brief Summary

Stroke remains a major global health burden, with acute ischemic stroke (AIS) accounting for more than 65% of all cases. Endovascular thrombectomy (EVT) has been established as the standard treatment ...

Eligibility Criteria

Inclusion

  • Symptoms and signs consistent with focal ischemia in the anterior or posterior circulation;
  • Large vessel occlusion of the anterior or posterior circulation (internal carotid artery, M1/M2 segment of the middle cerebral artery, vertebral artery, or basilar artery) confirmed by CTA/MRA/DSA;
  • Undergoing mechanical thrombectomy;
  • Age ≥18 years, both male and female;
  • Pre-stroke modified Rankin Scale (mRS) score ≤1;
  • Time from symptom onset to thrombectomy ≤24 hours, including wake-up stroke or unwitnessed stroke; symptom onset is defined as the "last known well" (LKW);
  • National Institutes of Health Stroke Scale (NIHSS) score ≥6 at admission;
  • ASPECTS ≥3 for anterior circulation occlusion, or pc-ASPECTS ≥6 for posterior circulation occlusion;
  • Written informed consent provided by the patient or their legal representative.

Exclusion

  • Simultaneous acute occlusion of both anterior and posterior circulation or bilateral hemispheric large vessel occlusions;
  • Complete clinical recovery at the end of EVT procedure;
  • Arterial dissection or intraoperative hemorrhage indicated by post-thrombectomy DSA;
  • Sedated and intubated patients without baseline NIHSS assessment;
  • Seizure at stroke onset interfering with baseline NIHSS assessment;
  • Bilateral fixed dilated pupils;
  • Severe allergy or absolute contraindication to sodium sivelestat;
  • Severe allergy or absolute contraindication to iodinated contrast agents;
  • Systolic blood pressure \>185 mmHg or diastolic blood pressure \>110 mmHg, uncontrolled despite antihypertensive therapy;
  • Blood glucose \<50 mg/dl (2.8 mmol/L) or \>400 mg/dl (22.2 mmol/L);
  • Platelet count \<50×10⁹/L;
  • Congenital or acquired bleeding diathesis, coagulation factor deficiency, or current use of oral anticoagulants with INR \>1.7;
  • Severe renal impairment, defined as serum creatinine \>3.0 mg/dl (265.2 μmol/L), GFR \<30 ml/min, or requirement for hemodialysis/peritoneal dialysis;
  • Inability to complete 90-day follow-up (e.g., no fixed residence, overseas patient);
  • Suspected vasculitis or septic embolism;
  • Suspected aortic dissection;
  • Pre-existing neurological or psychiatric disorders interfering with stroke assessment;
  • Pregnancy or lactation;
  • Confirmed rheumatic/autoimmune disease with long-term use of immunosuppressants or corticosteroids;
  • Current treatment with chemotherapy or other immunomodulatory agents (e.g., recombinant human granulocyte colony-stimulating factor, Xuebijing, ulinastatin, etc.);
  • Participation in another clinical trial that may interfere with study outcomes;
  • Any other condition that investigators deem unsuitable for participation or that may pose significant risk to the patient.
