Insights

Prothrombotic abnormalities are common in childhood stroke, affecting 20-50% of arterial ischaemic stroke cases and up to 99% of cerebral sinus venous thrombosis cases. These clotting disorders are increasingly recognized as key factors in childhood stroke development and recurrence.

Area of Science:

  • Pediatric Neurology
  • Hematology
  • Thrombosis Research

Background:

  • Childhood ischaemic stroke, including arterial ischaemic stroke (AIS) and cerebral sinus venous thrombosis (CSVT), presents significant morbidity and mortality.
  • Prothrombotic abnormalities, involving the coagulation, fibrinolytic, or endothelial systems, predispose individuals to pathological thrombus formation.
  • Understanding these abnormalities is crucial for developing effective management and prevention strategies for pediatric stroke.

Purpose of the Study:

  • To review the existing literature on prothrombotic markers in childhood ischaemic stroke.
  • To highlight the increasing evidence for the role of prothrombotic abnormalities in pediatric stroke.
  • To discuss the implications for clinical management and future research.

Main Methods:

  • Literature review of studies investigating prothrombotic abnormalities in childhood ischaemic stroke.
  • Analysis of reported frequencies of prothrombotic markers in pediatric AIS and CSVT.
  • Identification of specific associated prothrombotic conditions.

Main Results:

  • Prothrombotic abnormalities were identified in 20-50% of children with AIS and 33-99% of children with CSVT.
  • Associated factors in AIS include factor V Leiden mutation, elevated lipoprotein (a), protein C deficiency, and antiphospholipid antibodies.
  • The pathogenic role of these abnormalities in initial and recurrent childhood stroke is increasingly evident.

Conclusions:

  • Prothrombotic abnormalities are frequently observed in children with ischaemic stroke.
  • These findings underscore the importance of investigating clotting disorders in pediatric stroke patients.
  • Further multi-institutional prospective studies are needed to clarify the impact on treatment strategies.

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.
Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
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...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Stroke: Introduction and Types01:29

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 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...
