Summary
This study shows that real-time sonographic surveillance during amniocentesis significantly reduces fetal injury risks. This advanced technique enhances prenatal diagnosis safety by meticulously guiding the needle.
Area of Science:
- Medical Imaging
- Obstetrics & Gynecology
- Prenatal Diagnosis
Background:
- Amniocentesis is a common procedure for prenatal diagnosis.
- Potential risks include fetal injury and infection.
Purpose of the Study:
- To evaluate the safety and efficacy of permanent sonographic surveillance during second-trimester amniocentesis.
- To minimize complications associated with the amniocentesis procedure.
Main Methods:
- 81 amniocenteses performed under continuous real-time sonographic guidance using sectorial scanners.
- Detailed observation of needle progression through tissue layers to the amniotic sac.
- Technique adjusted to avoid fetal structures and limit needle depth.
Main Results:
- No complications were reported in any of the 81 procedures.
- Sonographic surveillance allowed continuous monitoring, preventing fetal injury.
- Infection risk was eliminated by maintaining a safe distance between the needle and the ultrasound transducer.
Conclusions:
- Permanent sonographic surveillance is a safe and effective method for second-trimester amniocentesis.
- This technique significantly reduces the risk of fetal injury and infection.
- Hemorrhage remains a potential risk, but was not observed in this study.
