Modeling Posthemorrhagic Hydrocephalus of Prematurity in Rats
Published on: March 28, 2025
Hydrocephalus in pfeiffer syndrome.
Summary
Pfeiffer syndrome frequently causes hydrocephalus due to ventricular dilation, often requiring shunting. This, combined with premature skull fusion, contributes to a poorer prognosis compared to similar conditions.
Area of Science:
- Neuroscience
- Genetics
- Pediatric Medicine
Background:
- Pfeiffer syndrome is a genetic disorder characterized by craniosynostosis.
- Hydrocephalus is a known complication in some craniofacial syndromes.
Purpose of the Study:
- To investigate the prevalence and severity of ventricular dilation and hydrocephalus in patients with Pfeiffer syndrome.
- To compare the prognosis of Pfeiffer syndrome with Crouzon and Apert syndromes regarding hydrocephalus.
Main Methods:
- Retrospective review of clinical records and CT scans from 11 Pfeiffer syndrome patients.
- Classification of ventriculomegaly severity and assessment of need for ventricular shunting.
Main Results:
- Ventricular dilation was observed in the majority of patients.
- Seven patients (64%) had severe ventriculomegaly classified as hydrocephalus, necessitating ventricular shunting.
- Extensive craniosynostosis and cranial base distortion were implicated in hydrocephalus development.
Conclusions:
- Hydrocephalus is a common and significant complication of Pfeiffer syndrome.
- The co-occurrence of hydrocephalus and premature sutural fusion worsens the prognosis of Pfeiffer syndrome.
- Craniofacial abnormalities, not primary cerebral anomalies, are the likely cause of hydrocephalus in Pfeiffer syndrome.

01:22Cerebral 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...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:14Increased Intracranial Pressure l: Introduction
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 expands, CSF and venous blood...
01:19Cerebral 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...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
