    Summary

    Fetoscopy, a minimally invasive procedure, is most effective before 20 weeks for fetal blood sampling to diagnose genetic disorders. It is not recommended for routine diagnosis of external malformations.

    Area of Science:

    • Medical imaging and minimally invasive procedures
    • Prenatal diagnostics
    • Fetal medicine

    Context:

    • Fetoscopy procedures were performed between December 1975 and July 1979.
    • 28 fetoscopies were conducted at the I. UFK Munich, with 25 performed under local anesthesia and real-time ultrasound guidance.
    • Procedures were divided into two groups: 20 before 24 weeks gestation (for medical/genetic reasons) and 8 between 26-38 weeks (for diagnostic purposes).

    Purpose:

    • To evaluate the efficacy and limitations of fetoscopy in prenatal diagnosis.
    • To determine the optimal gestational window for fetoscopy.
    • To assess the feasibility of fetal blood sampling and direct fetal intervention.

    Summary:

    • The study found that fetoscopy yielded the best results before 20 weeks gestation, utilizing a specialized scoring system.
    • External malformation diagnosis via fetoscopy is not currently recommended for routine clinical use.
    • Direct fetal blood circulation interventions are not yet feasible; however, fetal blood sampling for genetic enzyme defect diagnosis is possible up to 24 weeks gestation in specialized centers.

    Impact:

    • Fetoscopy is a valuable tool for prenatal diagnosis of genetic enzyme defects through fetal blood sampling, particularly before 20 weeks gestation.
    • The findings highlight the limitations of fetoscopy for diagnosing external malformations and direct fetal interventions.
    • This research informs the appropriate application of fetoscopy in specialized centers, emphasizing risk-benefit assessment.
