    This study presents results from 50 diagnostic chorionic villus samplings (CVS) for fetal chromosomal abnormalities. The procedure was successful in most cases, providing timely results for pregnancy management.

    Area of Science:

    • Perinatology
    • Medical Diagnostics
    • Genetics

    Background:

    • Prenatal diagnosis is crucial for identifying fetal chromosomal abnormalities.
    • Chorionic villus sampling (CVS) is an invasive diagnostic procedure.
    • Early genetic information aids in pregnancy management decisions.

    Purpose of the Study:

    • To evaluate the efficacy and safety of diagnostic chorionic villus sampling (CVS).
    • To assess the turnaround time for CVS results.
    • To report on early pregnancy outcomes following CVS.

    Main Methods:

    • Fifty diagnostic chorionic villus samplings (CVS) were performed between 9 and 11 weeks of amenorrhoea.
    • Procedures utilized a custom cannula with real-time ultrasound guidance.
    • Maternal serum alpha fetoprotein and endocervical swabs were collected routinely.

    Main Results:

    • Sampling was successful in 48 out of 50 cases.
    • Results were available within 8 days for most patients.
    • Six deliveries and 34 ongoing pregnancies were reported; 9 pregnancies were terminated or lost.

    Conclusions:

    • Diagnostic chorionic villus sampling (CVS) is an effective early prenatal diagnostic tool.
    • The procedure, when guided by ultrasound, offers timely genetic information.
    • Careful patient selection and procedural technique are vital for successful outcomes.
