Insights

This study presents two infants with severe brain arteriovenous malformations and congestive heart failure. Early diagnosis and understanding age-related features are crucial for managing these critical conditions in newborns.

Area of Science:

  • Pediatric Cardiology
  • Neurology
  • Medical Imaging

Background:

  • Endocranic arteriovenous malformations (AVMs) are rare but serious vascular anomalies.
  • Congestive cardiac failure in neonates can be caused by various factors, including AVMs.
  • The vein of Galen aneurysm is a specific type of AVM with significant hemodynamic impact.

Observation:

  • Two cases of neonates presenting with large endocranic AVMs and irreversible congestive cardiac failure are detailed.
  • The first case involved a newborn with a large angioma.
  • The second case involved a newborn with a large aneurysm of the vein of Galen.

Findings:

  • Infants with large endocranic AVMs, including vein of Galen aneurysms, can develop severe, irreversible congestive cardiac failure.
  • Age-related diagnostic features are critical for timely identification of these conditions.
  • The presented cases highlight the severity and rapid progression of symptoms.

Implications:

  • Early recognition of endocranic AVMs and associated cardiac compromise is vital for neonatal outcomes.
  • Understanding the specific age-related clinical and imaging findings aids in prompt diagnosis.
  • This review underscores the importance of a multidisciplinary approach in managing neonatal AVMs and heart failure.

Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
The Arch of Aorta01:10

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...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
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...
Cerebral Edema l: Introduction01:19

Cerebral Edema l: Introduction

Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
