Prenatal detection of anencephaly.

C Valenti, L von Micsky, J S Rose

    La Ricerca in Clinica E in Laboratorio
    |January 1, 1976
    PubMed
    Summary

    This study identified anencephaly, a severe neural tube malformation, in three pregnancies using sonography. Early screening for high-risk pregnancies is crucial for detecting such fetal anomalies.

    Area of Science:

    • Medical Imaging
    • Prenatal Diagnosis
    • Teratology

    Background:

    • Advanced maternal age, hydramnios, and abnormal vaginal bleeding are clinical indicators for suspecting fetal anomalies.
    • Neural tube malformations represent a significant category of congenital abnormalities.

    Observation:

    • Sonography was employed to investigate suspected fetal anomalies in three patients during the second trimester.
    • Clinical suspicion arose from advanced maternal age, hydramnios, and abnormal vaginal bleeding.

    Findings:

    • Sonographic examination revealed anencephaly in all three cases.
    • Anencephaly diagnosis was corroborated by roentgenograms.
    • Elevated amniotic fluid alpha-fetoprotein levels confirmed the diagnosis in one case.
    • Antenatal diagnosis was validated post-termination in all three abortuses.

    Implications:

    • Early screening for neural tube malformations in at-risk pregnancies is strongly recommended.
    • Accurate prenatal diagnosis of fetal anomalies like anencephaly is vital for clinical management.
    • This highlights the importance of advanced imaging techniques in identifying severe congenital defects.
