[Prenatal diagnosis. A 35 amniocentesis study (author's transl)]
Anales Espanoles De Pediatria
|January 1, 1980
Summary
This study analyzed 35 amniocentesis procedures, detecting chromosomal abnormalities in 3 high-risk pregnancies. Alpha-fetoprotein levels were normal, suggesting its limited role in predicting neural-tube defects in this cohort.
Area of Science:
- Prenatal Diagnosis
- Cytogenetics
- Biochemistry
Context:
- Amniocentesis is a key prenatal diagnostic tool.
- Early detection of chromosomal anomalies is crucial for high-risk pregnancies.
- Alpha-fetoprotein (AFP) screening aids in predicting neural-tube defects.
Purpose:
- To present the cytogenetic findings from 35 amniocentesis procedures.
- To evaluate the utility of alpha-fetoprotein levels in conjunction with amniocentesis.
- To discuss the indications for early prenatal diagnosis of chromosomal abnormalities.
Summary:
- Cytogenetic analysis was performed on 28 amniocentesis samples, identifying trisomy 21, a 14/21 translocation with trisomy 21, and partial trisomy 2.
- Alpha-fetoprotein levels were assessed in 10 cases and found to be within normal ranges.
- The study highlights the importance of amniocentesis for detecting chromosomal anomalies and comments on AFP's role.
Impact:
- Provides data on the prevalence of specific chromosomal abnormalities detected via amniocentesis.
- Contributes to understanding the diagnostic yield of cytogenetic analysis in prenatal screening.
- Informs clinical practice regarding the combined use of amniocentesis and AFP testing for fetal assessment.
