Detailed ultrasound as a screening method for craniospinal abnormalities
Clinical and Experimental Obstetrics & Gynecology
|January 1, 1987
Summary
High-resolution ultrasound effectively screens for craniospinal anomalies in low-risk pregnancies. Improved detection rates (87%) were observed with timely attendance, suggesting a valuable screening tool.
Area of Science:
- Medical Imaging
- Obstetrics
- Prenatal Diagnosis
Background:
- Craniospinal anomalies pose significant risks during pregnancy.
- Effective screening methods are crucial for early detection and intervention.
- Low-risk populations require validated screening protocols.
Purpose of the Study:
- To evaluate high-resolution diagnostic ultrasound as a screening tool for craniospinal anomalies.
- To assess screening effectiveness in a low-risk second-trimester pregnancy population.
- To compare ultrasound screening with serum alpha-feto protein screening.
Main Methods:
- Retrospective analysis of 83,403 second-trimester pregnancies.
- Assessment of high-resolution diagnostic ultrasound effectiveness.
- Evaluation of detection rates in a subgroup with satisfactory screening attendance.
Main Results:
- Overall screening effectiveness was approximately 60%.
- Late attendance was a primary cause of screening failure.
- A subgroup with satisfactory attendance showed an 87% detection rate.
Conclusions:
- High-resolution ultrasound demonstrates potential as a viable screening method for craniospinal anomalies.
- Timely patient attendance significantly enhances screening effectiveness.
- Further cost-benefit analysis is warranted compared to existing screening services.
