Summary
Embryoscopy and fetoscopy allow direct visualization of embryo/fetus development for early diagnosis and potential fetal therapy. This advanced technique offers new possibilities for prenatal care and intervention during early pregnancy.
Area of Science:
- Perinatal Medicine
- Reproductive Biology
- Medical Imaging
Background:
- Embryoscopy and fetoscopy provide external access to the developing embryo/fetus.
- These techniques utilize high-resolution fiber optics for direct visualization.
- Applications span early pregnancy for diagnosis and potential therapy.
Purpose of the Study:
- To highlight the significance of embryoscopy and fetoscopy (embryofetoscopy) in perinatal medicine.
- To explore the potential of embryofetoscopy in advancing fetal therapy.
- To review the diagnostic capabilities of embryofetoscopy in early pregnancy.
Main Methods:
- Direct visualization of the embryo/fetus using high-resolution fiber optic equipment.
- Identification of developmental milestones between 4 and 8 weeks post-conception.
- Experimental fetal blood sampling for therapeutic applications.
Main Results:
- Successful identification of developmental milestones and anomalies.
- Confirmation of diagnoses previously made by ultrasound.
- Experimental demonstration of fetal blood sampling feasibility.
Conclusions:
- Embryoscopy and fetoscopy are crucial for prenatal diagnosis and offer potential for fetal therapy.
- The technology enables early detection of developmental issues and confirmation of ultrasound findings.
- Future applications include immunologically tolerant embryonic interventions like gene or cell therapy.
