    Area of Science:

    • Medical Genetics
    • Prenatal Diagnosis
    • Fetal Medicine

    Background:

    • Cytogenetic prenatal diagnosis is essential for identifying fetal chromosomal aberrations.
    • Indications for examination include ultrasound findings, advanced maternal age, and specific serum markers (AFP, HCG, estriol).

    Observation:

    • Four cases involving Patau syndrome, Down syndrome (two cases), and Klinefelter syndrome are presented.
    • Cordocentesis was utilized for rapid and accurate fetal karyotype determination.
    • Ultrasonic examinations were compared with post-mortem data from abortuses.

    Findings:

    • Cordocentesis proved expedient for timely and precise karyotype analysis.
    • Integrated diagnostic approach combining ultrasound, cytogenetics, biochemistry, and morphology is vital.
