Insights

Basilar artery stroke (BAS) in children is rare, with an incidence of 0.037 per 100,000 children annually. Despite diagnostic delays, outcomes are more favorable than in adults, especially with a lower PedNIHSS score.

Area of Science:

  • Pediatric Neurology
  • Vascular Neurology
  • Epidemiology

Background:

  • Basilar artery stroke (BAS) is poorly understood in pediatric populations.
  • This study aims to elucidate the characteristics and outcomes of childhood BAS.

Purpose of the Study:

  • To determine the incidence of BAS in children.
  • To analyze clinical presentation, risk factors, radiological findings, and treatment approaches.
  • To evaluate outcomes and identify prognostic factors for childhood BAS.

Main Methods:

  • A prospective, population-based study of pediatric arterial ischemic stroke cases.
  • Systematic literature review to identify additional childhood BAS cases.
  • Analysis of incidence, clinical features, etiology, treatment, and outcomes.

Main Results:

  • The incidence of BAS in children was found to be 0.037 per 100,000 children per year.
  • Common symptoms included impaired consciousness, hemiparesis/quadriparesis, and bulbar dysfunction.
  • A significant proportion of cases had vasculopathic etiology or unknown causes, with a median Pediatric National Institutes of Health Stroke Scale (PedNIHSS) score of 15.
  • Good outcomes (modified Rankin Scale 0-2) were observed in 45 patients, while eight died. A PedNIHSS score of 17 or less was a prognostic factor for favorable outcomes.

Conclusions:

  • Childhood BAS is a rare condition with a more favorable prognosis compared to adults.
  • Delays in diagnosis and treatment are common but do not preclude better outcomes.
  • Lower PedNIHSS scores (≤17) are associated with improved outcomes in pediatric BAS.

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...
