Chorionic villi sampling is a reliable method for diagnosing genetic diseases, with a low risk of complications. This technique aids in identifying chromosome anomalies, supporting informed reproductive decisions.

Area of Science:

  • Prenatal diagnostics
  • Human genetics
  • Cytogenetics

Context:

  • Chorionic villi sampling (CVS) is a key prenatal diagnostic tool.
  • Indications for CVS include advanced maternal age, parental chromosomal abnormalities, and family history of genetic disorders.
  • This study evaluates the efficacy and safety of CVS in a clinical setting.

Purpose:

  • To assess the reliability and safety of chorionic villi forceps biopsies for prenatal genetic disease diagnosis.
  • To determine the success rate of sampling and the incidence of complications.
  • To evaluate the impact of CVS on pregnancy outcomes.

Summary:

  • 531 chorionic villi forceps biopsies were performed for genetic disease screening.
  • Sampling was successful in 95.5% of cases, with common indications being advanced maternal age and X-linked diseases.

  • The miscarriage rate following CVS was 3.9%, with 8.7% of cases resulting in elective abortion.

    • Impact:

    • The study demonstrates that chorionic villi sampling is a reliable cytogenetic technique for diagnosing chromosome anomalies.
    • The low risk associated with the sampling procedure supports its widespread clinical application.
    • Findings contribute to informed decision-making in prenatal genetic testing and management.
