[Our experience in the prenatal echographic diagnosis of spinal dysraphism in the fetus]
Insights
This study analyzed ultrasound signs for diagnosing fetal spinal dysraphism, including spina bifida. Ultrasound offers valuable direct and indirect indicators for prenatal diagnosis of these neural tube defects.
Area of Science:
- Medical Imaging
- Prenatal Diagnosis
- Fetal Medicine
Background:
- Prenatal diagnosis of fetal anomalies is crucial for timely intervention.
- Spinal dysraphism, a group of neural tube defects, presents significant diagnostic challenges.
- Ultrasound is a primary imaging modality in prenatal screening.
Purpose of the Study:
- To analyze ultrasound signs for diagnosing fetal spinal dysraphism.
- To identify the most useful ultrasound indicators for definitive diagnosis.
- To compare the reliability of ultrasound findings with biochemical diagnosis.
Main Methods:
- Retrospective analysis of 141 cases with fetal structural and chromosomal anomalies.
- Detailed examination of 17 cases of spinal dysraphism (spina bifida, meningocele, meningoencephalocele).
- Evaluation of direct and indirect ultrasound signs and echoscopy techniques across different gestational terms.
Main Results:
- Ultrasound demonstrates specific direct and indirect signs useful for diagnosing spinal dysraphism.
- Echoscopy techniques were adapted for detecting these signs throughout pregnancy.
- A partial comparison indicated the reliability of ultrasound compared to biochemical markers.
Conclusions:
- Ultrasound is a valuable tool for the prenatal diagnosis of fetal spinal dysraphism.
- Specific ultrasound signs and techniques enhance diagnostic accuracy.
- Further comparison studies are warranted to fully elucidate the role of ultrasound versus biochemical markers.
Abstract:
The investigation consists of 141 cases of prenatal diagnosing structural and chromosomal anomalies of the fetus. Seventeen of the cases, quoted above, concern spinal dysraphism (spina bifida, occipital meningocele, meningoencephalocele). It has been made an analysis of ultrasound signs at this group of defects which turned out the most useful for the definite diagnosis. According to the literary survey and author's experience are formed two main groups of indices at echo-sounding study--direct and indirect. There have been considered the technics of echoscopy in searching the signs of different terms of pregnancy. It has been made a partial comparison of the reliability in the two groups ultrasound signs with this in biochemical diagnosis of spinal dysraphism in the fetus.
