Radiological strategy in acute stroke in children

Area of Science:

• Neurology
• Pediatric Medicine
• Radiology

Background:

• Pediatric stroke is a critical neurological event requiring accurate diagnosis and management.
• Understanding the epidemiological patterns and etiological factors of pediatric stroke is essential for effective treatment strategies.

Purpose of the Study:

• To determine the prevalence of ischemic versus hemorrhagic pediatric stroke.
• To identify the various etiologies associated with pediatric stroke.
• To evaluate the diagnostic efficacy of imaging modalities in acute pediatric stroke management.

Main Methods:

• Retrospective analysis of 41 pediatric patients (age 5-16) with acute stroke over a 10-year period.
• Utilized magnetic resonance imaging (MRI), computed tomography (CT), and intra-arterial digital subtraction angiography (IADSA) for diagnostic assessment.
• Categorized strokes into ischemic and hemorrhagic types and investigated underlying causes.

Main Results:

• Ischemic strokes accounted for 59% (24 cases) and hemorrhagic strokes for 41% (17 cases).
• Identified diverse etiologies including arteriovenous malformation, cavernoma, aneurysm, sickle-cell disease, venous sinus thrombosis, and prothrombotic states.
• Etiology remained unknown in 20.5% of cases.
• MRI demonstrated superior diagnostic information compared to CT in acute pediatric stroke.

Conclusions:

• Ischemic strokes are more prevalent than hemorrhagic strokes in the pediatric population studied.
• A wide range of etiological factors contribute to pediatric stroke, necessitating comprehensive diagnostic workups.
• Magnetic resonance imaging (MRI) is the preferred initial imaging modality for acute pediatric stroke due to its comprehensive diagnostic capabilities.
