Area of Science:

  • Perinatology
  • Fetal Medicine
  • Endoscopic Surgery

Background:

  • Early pregnancy diagnosis and intervention are crucial.
  • Non-invasive prenatal screening may require confirmation.
  • Embryonic development requires detailed study.

Purpose of the Study:

  • To evaluate transabdominal embryoscopy for embryo visualization and blood sampling in early pregnancy.
  • To assess the feasibility and safety of the procedure.
  • To explore potential applications in diagnostics and therapy.

Main Methods:

  • Transabdominal embryoscopy using a 1mm fiberoptic endoscope under ultrasound guidance.
  • Performed on 20 women undergoing pregnancy termination between 9-12 weeks gestation.
  • Blood sampling from chorionic plate or umbilical cord vessels.

Main Results:

  • Complete embryonic anatomical survey achieved in 100% of cases.
  • Embryonic circulation accessed in 14 cases, with successful blood retrieval in 10 (71.4%).
  • Procedure duration averaged 15 minutes with no maternal complications.

Conclusions:

  • Transabdominal embryoscopy is a feasible and safe diagnostic tool for early pregnancy.
  • It enables detailed embryonic examination and access to embryonic circulation.
  • Potential applications include confirmation of diagnoses and future gene/cell therapies.
