Insights

Hyperacute therapy for pediatric acute ischemic stroke (AIS) is underutilized due to presentation delays, mild symptoms, contraindications, and lack of vessel occlusion. Improving these factors is crucial for increasing treatment rates in children with AIS.

Area of Science:

  • Pediatric Neurology
  • Stroke Medicine
  • Emergency Medicine

Background:

  • Acute ischemic stroke (AIS) in children is a rare but serious condition.
  • Hyperacute therapies aim to restore blood flow and minimize brain damage.
  • Established institutional pathways are critical for timely stroke treatment.

Purpose of the Study:

  • To evaluate factors influencing hyperacute therapy eligibility and utilization in children with AIS.
  • To assess the effectiveness of an institutional acute stroke treatment pathway implemented in 2005.

Main Methods:

  • Retrospective analysis of a prospectively enrolled single-center cohort of children (2 to <18 years) with AIS from 2005-2017.
  • Descriptive statistics used to summarize clinical data, presentation details, and Pediatric NIH Stroke Scale (PedNIHSS) scores.
  • Eligibility and therapy administration assessed based on the institutional stroke pathway at presentation.

Main Results:

  • Only 6% (5/90) of children with AIS received hyperacute therapy (intravenous tissue plasminogen activator [IV-tPA] and/or endovascular therapy [EVT]).
  • Among those presenting within 4.5 hours, only 6 met criteria for IV-tPA (PedNIHSS ≥6, no contraindications, vessel occlusion).
  • Among eligible children presenting within 6 hours after EVT availability, 43% had large vessel occlusion, but only 2 received EVT.

Conclusions:

  • Low rates of hyperacute therapy utilization in pediatric AIS are attributed to delayed presentation and diagnosis.
  • Mild neurologic deficits, medical contraindications to IV-tPA, and absence of vessel occlusion on imaging are significant barriers.
  • Optimizing stroke pathways and addressing these contributing factors are essential to improve treatment rates in children.
