    Contact embryoscopy offers a novel method for early prenatal diagnosis of fetal extremity malformations. This technique visualizes fetal hands and fingers during the first trimester, aiding in the detection of conditions like Ellis Van Creveld Syndrome.

    Area of Science:

    • Obstetrics and Gynecology
    • Fetal Medicine
    • Diagnostic Imaging

    Context:

    • First-trimester prenatal diagnosis presents challenges in detailed fetal anatomical assessment.
    • Existing methods may have limitations in early pregnancy visualization.

    Purpose:

    • To introduce and evaluate contact embryoscopy as a new technique for first-trimester fetal examination.
    • To assess the feasibility and utility of contact embryoscopy for detecting extremity malformations.

    Summary:

    • Contact embryoscopy involves applying a hysteroscope to the ovular membranes for in utero visualization.
    • Performed between 8-12 weeks gestation, the technique successfully visualized fetal hands and fingers in 41 out of 50 cases.
    • This method can be complemented by ultrasound and fetoscopy if initial visualization is unsuccessful.

    Impact:

    • Contact embryoscopy shows promise for early detection of congenital limb malformations, such as ectrodactyly and Ellis Van Creveld Syndrome.
    • This technique may improve diagnostic accuracy for specific fetal anomalies in early pregnancy.
    • Potential to guide early intervention or genetic counseling for affected pregnancies.
