Prognostic signs in fetal hydrocephalus

Area of Science:

• Medical Science
• Obstetrics
• Pediatric Neurology

Background:

• Fetal hydrocephalus diagnosis is crucial for determining prognosis and guiding management.
• Modern ultrasound techniques enable early detection of fetal hydrocephalus, often before 20 weeks of gestation.
• Associated anomalies are common, present in 84% of fetal hydrocephalus cases.

Purpose of the Study:

• To assess the prognosis of fetal hydrocephalus based on antenatal diagnosis and ultrasound findings.
• To evaluate the outcomes of different management strategies, including postnatal shunting and conservative treatment.
• To determine the potential role of antenatal interventions for fetal hydrocephalus.

Main Methods:

• Antenatal diagnosis of fetal hydrocephalus in 38 cases using ultrasound.
• Prognostic assessment based on specific criteria to categorize severity.
• Postnatal evaluation and follow-up of treated cases (7 months to 5 years).
• Analysis of etiological factors and associated anomalies.

Main Results:

• Of 38 cases, 23 were severely affected; 10 had a more favorable prognosis.
• Eight of the 10 favorable prognosis cases were delivered via elective cesarean section.
• Six of the 10 managed cases showed normal or subnormal development; 4 had severe retardation.
• Ventriculoatrial shunting was performed in 9 neonates; 1 was managed conservatively.

Conclusions:

• Early antenatal detection of fetal hydrocephalus is possible with ultrasound.
• Favorable prognosis cases can achieve good outcomes with early postnatal therapy.
• Antenatal shunting is indicated only in a minority of fetal hydrocephalus cases.
