[Clinical experience with fetoscopy (author's transl)]

R Rauskolb

    Geburtshilfe Und Frauenheilkunde
    |April 1, 1977
    PubMed
    Summary

    Fetoscopy allows direct intrauterine visualization of the fetus, with successful visualization in 23 of 26 cases. Optimal results depend on amniotic fluid quality, timing, and observer expertise for diagnostic evaluation.

    Area of Science:

    • Medical Imaging
    • Fetal Medicine
    • Endoscopy

    Context:

    • Minimally invasive fetal visualization techniques are crucial for prenatal diagnosis.
    • Fetoscopy offers direct intrauterine access for fetal examination.
    • Ultrasound-guided insertion facilitates safe and uncomplicated fetoscope placement.

    Purpose:

    • To evaluate the diagnostic value and feasibility of fetoscopy.
    • To assess the extent and quality of fetal visualization achievable with fetoscopy.
    • To determine the success rate and influencing factors for diagnostic fetoscopy.

    Summary:

    • Fetoscopy, using a 3.9 mm external diameter trocar, enables direct intrauterine fetal visualization.
    • Successful visualization occurred in 23 of 26 fetuses, though limited to 50 degrees field of view.
    • Factors influencing success include amniotic fluid quality, second-trimester timing (15-18 weeks), and operator experience.

    Impact:

    • Fetoscopy provides detailed visualization of fetal parts, aiding in prenatal diagnosis.
    • Successful total fetal visualization was achieved in 39% of cases.
    • The procedure is justified for high-risk pregnancies and potential avoidance of abruptio, with potential for fetal blood sampling.
