Prenatal diagnosis and pediatric neurosurgery

Area of Science:

• Medical Imaging
• Prenatal Medicine
• Pediatric Neurosurgery

Background:

• Real-time ultrasound imaging and high-quality equipment have increased prenatal diagnosis of congenital abnormalities.
• Maternal serum screening (alpha-fetoprotein, beta-human chorionic gonadotropin, unconjugated estriol) enhances detection sensitivity.
• A dedicated Prenatal Diagnosis and Treatment Center was established to manage care for fetuses and newborns with malformations.

Purpose of the Study:

• To evaluate the accuracy and impact of prenatal diagnostic methods for central nervous system disorders.
• To assess the role of counseling in parental decision-making for affected pregnancies.
• To analyze outcomes for fetuses diagnosed with neural tube defects and hydrocephalus.

Main Methods:

• Utilized advanced ultrasound imaging and maternal serum screening for prenatal diagnosis.
• Diagnosed 50 singleton pregnancies with central nervous system disorders between January 1990 and June 1993.
• Counseled parents regarding diagnoses, including neural tube defects and hydrocephalus.

Main Results:

• 37 fetuses diagnosed with neural tube defects (5 anencephalic, 1 encephalocele, 31 meningomyeloceles with hydrocephalus).
• 18 of 31 meningomyelocele cases were terminated; 13 carried to term.
• High diagnostic accuracy (1 incorrect diagnosis in 50 cases); outcomes for hydrocephalus varied, with some requiring shunts or showing normal development.

Conclusions:

• Accurate prenatal diagnosis of fetal central nervous system disorders is highly achievable.
• Prenatal diagnosis facilitates informed parental counseling and decision-making.
• Effective prenatal diagnosis is crucial for managing pediatric neurosurgical conditions and guiding fetal/newborn care.
