Summary
Pediatric dural arteriovenous malformations (dAVMs) are rare and dangerous. Prompt endovascular embolization offers the best chance for favorable outcomes in children with dAVMs, despite potential complications.
Area of Science:
- Neurology
- Pediatric Neurosurgery
- Vascular Malformations
Background:
- Pediatric dural arteriovenous malformations (dAVMs) are rare, complex vascular lesions with high mortality.
- Management of pediatric dAVMs requires specialized neurosurgical and endovascular expertise.
Observation:
- Three pediatric dAVM cases presented with macrocrania and extracranial venous distension.
- Two cases developed dural sinus thrombosis pre-intervention, an unusual presentation.
- Complications included dural sinus thrombosis, hemorrhage, venous hypertension, and seizures.
Findings:
- Staged endovascular embolization was the treatment strategy for all three cases.
- One patient had a favorable outcome, while two experienced poor outcomes.
- Prompt endovascular embolization is associated with the best available results for pediatric dAVMs.
Implications:
- Endovascular embolization is crucial for managing pediatric dAVMs.
- Venous collateral circulation to internal jugular veins may improve treatment outcomes.
- Further research is needed to optimize management strategies and improve outcomes for pediatric dAVMs.

01:22Cerebral Edema ll: Pathophysiology
14
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...

01:18Anatomy of the Brain: Ventricles
10.3K
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.

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component...
