Insights

Perinatal arterial stroke (PAS) in preterm infants is linked to antenatal and perinatal factors like twin-to-twin transfusion and hypoglycemia. Imaging shows middle cerebral artery involvement varies with gestational age.

Area of Science:

  • Neonatal neurology
  • Pediatric stroke research
  • Perinatal medicine

Background:

  • Perinatal arterial stroke (PAS) studies often exclude preterm infants.
  • Understanding PAS in this vulnerable population is crucial.

Purpose of the Study:

  • To analyze imaging findings in preterm infants with PAS.
  • To identify antenatal and perinatal risk factors for PAS in preterm infants.

Main Methods:

  • Hospital-based, case-control study.
  • 31 preterm infants with confirmed PAS (cases).
  • Matched controls for comparison.

Main Results:

  • PAS predominantly affected the left hemisphere (61%).
  • Middle cerebral artery distribution was most common.
  • Independent risk factors included twin-to-twin transfusion, fetal heart rate abnormality, and hypoglycemia.
  • Branch involvement patterns varied by gestational age (28-32 vs. >32 weeks).

Conclusions:

  • Preterm PAS is associated with prenatal, perinatal, and postpartum factors.
  • No maternal risk factors were identified.
  • Cerebral artery branch involvement evolves with increasing gestational age.

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...

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.
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...
Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
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...
