Chorionic villus sampling (CVS) is a safe method for early prenatal genetic diagnosis. A study found no significant difference in perinatal outcomes between CVS and amniocentesis, supporting its continued use.

Area of Science:

  • Medical Genetics
  • Maternal-Fetal Medicine
  • Obstetrics

Background:

  • Chorionic villus sampling (CVS) is widely used for early prenatal genetic diagnosis.
  • Concerns exist regarding potential increased perinatal mortality with CVS compared to amniocentesis.
  • This study addresses these concerns by analyzing regional data.

Purpose of the Study:

  • To evaluate the obstetric and perinatal outcomes of pregnancies undergoing chorionic villus sampling.
  • To compare these outcomes with a matched control group to assess safety concerns.
  • To determine if CVS can be safely continued as a first-trimester diagnostic option.

Main Methods:

  • Retrospective analysis of 144 cases where pregnancy progressed beyond 28 weeks gestation following CVS.

  • Selection of a procedure-free control group matched for parity.
  • Comparison of perinatal mortality and obstetric performance between the CVS and control groups.

    • Main Results:

    • No significant differences were observed in perinatal outcomes between the chorionic villus sampling group and the matched control group.
    • Obstetric performance metrics were comparable between the two groups.
    • The data indicates comparable safety profiles regarding perinatal outcomes.

    Conclusions:

    • Chorionic villus sampling demonstrates a favorable safety profile concerning perinatal outcomes when compared to amniocentesis.
    • The procedure offers significant advantages for first-trimester genetic diagnosis.
    • Continued offering of chorionic villus sampling services is supported by these findings.
