Summary
Fetal neurosurgery can benefit selected fetuses with hydrocephalus diagnosed before 32 weeks. While outcomes vary, this intrauterine treatment shows no maternal or infectious complications.
Area of Science:
- Perinatology
- Fetal Surgery
- Neurodevelopmental Pediatrics
Background:
- Hydrocephalus is a frequent and severe fetal illness.
- Advanced diagnostics like ultrasonography and MRI aid in early detection.
- Fetal Medicine Services are crucial for managing complex pregnancies.
Purpose of the Study:
- To evaluate the outcomes of intrauterine treatments for fetal hydrocephalus.
- To assess the efficacy of neurosurgical interventions in preventing severe outcomes.
- To analyze neurodevelopmental results in children treated in utero.
Main Methods:
- Treatment of 57 fetuses with hydrocephalus using cephalocentesis, ventricular-amniotic shunting, and neuroendoscopy.
- Open surgical correction for myelomeningocele in 8 fetuses to prevent hydrocephalus.
- Long-term follow-up (over 3 years) including intelligence quotient (IQ) assessment.
Main Results:
- Of 39 followed patients, 26 had normal IQ, 6 mild/moderate handicaps, and 7 severe handicaps.
- Only 2 of 8 myelomeningocele patients required shunting post-correction.
- No maternal morbidity or infectious complications were observed in intrauterine treatments.
Conclusions:
- Fetal neurosurgical procedures can benefit carefully selected cases of isolated, progressive hydrocephalus diagnosed before 32 weeks.
- Improved diagnostic accuracy has reduced the number of eligible patients.
- Intrauterine interventions offer a potential treatment pathway with a favorable safety profile.

01:14Fetal 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...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
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...
01:14Increased 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...
01:29Increased 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...
01:19Cerebral 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...
