Transabdominal chorionic villus sampling in the first trimester is a safe procedure with a low miscarriage rate. This placental biopsy method offers advantages for early pregnancy assessment.

Area of Science:

  • Obstetrics and Gynecology
  • Prenatal Diagnostics

Background:

  • First-trimester prenatal diagnosis is crucial for early pregnancy management.
  • Transabdominal chorionic villus sampling (CVS) is an invasive diagnostic procedure.

Purpose of the Study:

  • To evaluate the safety and outcomes of transabdominal CVS in the first trimester.
  • To assess the efficacy of the transabdominal approach for placental biopsy.

Main Methods:

  • Retrospective review of the first 100 patients undergoing transabdominal CVS.
  • Follow-up data collection on pregnancy outcomes.

Main Results:

  • Out of 100 patients, 24 delivered, 68 progressed normally beyond 24 weeks, and 7 pregnancies were terminated.
  • Only 1 spontaneous miscarriage occurred, indicating a low event rate.

Conclusions:

  • Transabdominal CVS is a safe and effective first-trimester diagnostic procedure.
  • The transabdominal approach demonstrates favorable outcomes and a low risk of spontaneous miscarriage.
