-This is a diagnostic outpatient office procedure performed under ultrasound guidance without anesthesia.
-The catheter is placed directly into the placental tissue without entering the amniotic cavity.
-Chorionic villi, which are placental precursors, are aspirated from a pregnant uterus between 10 and 12 weeks’ gestation.
-The tissue is sent to the laboratory for karyotyping.
-The chromosomes of the villi are almost always identical to those of the embryo.
Nature of Tissue Obtained:
The procedure can be performed either transcervically or transabdominally. Since the fetus and chorionic villi are both derived from a common origin (the zygote), their karyotype is identical more than 99% of the time.
Risks associated with procedure:
Procedure-related pregnancy loss rate is 0.7%.
