NCT07550257

Brief Summary

This observational study aims to investigate the real-world effectiveness and safety of different treatment strategies for acute ischemic stroke (AIS) in Chinese children under 18 years of age. Its primary research question is: In real-world clinical practice, does endovascular therapy (e.g., stent retriever thrombectomy, aspiration thrombectomy) improve 90-day functional outcomes in pediatric AIS patients with acute anterior or posterior circulation large vessel occlusion? Children under 18 years of age receiving routine AIS diagnosis and treatment at approximately 25-35 study centers across China will undergo neurological function assessments, imaging examinations, and evaluations of growth, development, and psychosocial status at baseline, 24 hours post-procedure, 7 days post-procedure or at hospital discharge, and at 90 days and 6 months post-onset. Adverse events will also be documented.

Outcome Measures

Primary Outcomes (1)

  • Pediatric Modified Rankin Scale (ped-mRS) Score at 90 Days

    Primary Outcome Measure assessed by the pediatric modified Rankin Scale (ped-mRS) at 90 days (±7 days) post-stroke onset. The ped-mRS is a 7-point ordinal scale (0=no symptoms to 6=death). The full ordinal distribution of scores will be analyzed as the primary efficacy endpoint.

    90 days (±7 days) post-stroke onset

Secondary Outcomes (3)

  • Proportion of Patients with ped-mRS 0-1, 0-2, 0-3 at 90 Days

    90 days (±7 days) post-stroke onset

  • Change in ped-NIHSS Score at 24 Hours

    24 hours (±12 hours) post-procedure

  • Pediatric Modified Rankin Scale (ped-mRS) Score at 6 Months

    6 months (±14 days) post-stroke onset

Other Outcomes (2)

  • Target Vessel Final Recanalization Rate (eTICI 2b-3) on DSA

    immediately post-procedure

  • Target Vessel Recanalization Rate on CTA/MRA/DSA at 7 Days or Discharge

    7 days (±1 day) post-procedure or at discharge

Study Arms (1)

All eligible children aged 28 days to <18 years with acute ischemic stroke (AIS) enrolled consecutiv

All eligible children aged 28 days to \<18 years with acute ischemic stroke (AIS) enrolled consecutively from approximately 25-35 participating centers in China. Patients receive standard clinical management without treatment restrictions. Data collected include baseline demographics, clinical presentation, treatment strategies (medical therapy alone or endovascular treatment including stent retrieval, aspiration, balloon angioplasty, stenting, or intra-arterial thrombolysis), imaging parameters, safety outcomes, and functional outcomes assessed by pediatric modified Rankin Scale (ped-mRS) at 90 days and 6 months.

Other: Standard Clinical Management

Interventions

Participants receive routine clinical care per each center's standard practice. Treatment may include medical therapy (antiplatelet agents, anticoagulation) and/or endovascular treatment (stent retriever, aspiration thrombectomy, balloon angioplasty, stenting, or intra-arterial thrombolysis), as determined by the treating physician. No protocol-mandated intervention is applied.

Sampling MethodNon-Probability Sample
Study Population

This study will prospectively enroll consecutive patients aged 28 days to \<18 years with acute ischemic stroke (AIS) from approximately 25-35 participating centers across China. Eligible patients must have first-ever stroke with onset ≤7 days prior to admission, confirmed by computed tomography (CT) or magnetic resonance imaging (MRI). Both patients receiving standard medical therapy alone and those receiving endovascular treatment (including stent retrieval, aspiration thrombectomy, balloon angioplasty, stenting, or intra-arterial thrombolysis) will be included. Patients with lack of imaging confirmation, history of hypoxic-ischemic encephalopathy, ischemic stroke caused by cerebral venous system, or concurrent indistinguishable ischemic and hemorrhagic stroke will be excluded. The study aims to enroll a target sample size of \>1000 patients.

You may qualify if:

  • Age \>28 days and \<18 years;
  • Presence of stroke-related symptoms (hemiparesis, facial palsy, aphasia, altered level of consciousness, seizure, headache) or atypical symptoms (sudden lethargy or irritability, crying, feeding difficulties, incontinence, sensory loss, ataxia, vertigo, nausea and/or vomiting, neck pain, fever);
  • First-ever stroke and onset within ≤7 days prior to admission;
  • Acute ischemic stroke confirmed by computed tomography (CT) or magnetic resonance imaging (MRI);
  • Legal guardian provides signed informed consent;
  • For children aged ≥8 years to \<18 years who are conscious and without comprehension impairment, assent obtained from the child;

You may not qualify if:

  • Lack of imaging examination or stroke diagnosed without imaging
  • History of hypoxic-ischemic encephalopathy
  • Ischemic stroke caused by cerebral venous system
  • Concurrent presence of indistinguishable ischemic and hemorrhagic stroke
