Summary
This study shows that combining two cordocentesis techniques is a safe and effective method for obtaining fetal blood samples. The procedure resulted in a low fetal loss rate of 0.93%.
Area of Science:
- Medical procedures
- Fetal medicine
- Diagnostic techniques
Background:
- Cordocentesis is a valuable tool for fetal diagnosis.
- Minimizing procedural risks is crucial for fetal well-being.
Purpose of the Study:
- To evaluate the safety and efficacy of a combined guide-assisted and free-hand cordocentesis technique.
- To determine the fetal loss rate associated with this combined approach.
Main Methods:
- Two hundred and sixteen diagnostic cordocenteses were performed.
- A novel technique combining guide-assisted and free-hand needle insertion was employed.
- Sonography with color Doppler was used for vessel identification and flow direction.
Main Results:
- The overall fetal loss rate was 0.93% (2 out of 216 procedures).
- Most punctures (62%) occurred at the placental insertion of the umbilical cord.
- Successful fetal blood sampling was achieved in the vast majority of cases.
Conclusions:
- The combined cordocentesis technique is safe and highly successful for fetal blood sampling.
- This method offers a reliable approach for prenatal diagnosis.
