Is ultrasound guidance necessary for successful transcervical chorion villus sampling?

  • I. Z. MacKenzie

Abstract

With the present rate of amniocentesis in England and Wales at 2–3% of all deliveries, there are approximately 15 000 amniocenteses performed annually. The majority are for karyotyping on the grounds of advanced maternal age, and a smaller proportion are performed to investigate raised maternal serum AFP. It is probable that the number seeking karyotyping for advanced maternal age will increase with an increasing awareness within the community of the risks associated with age. Further, the request to know ‘if my baby is normal’ may well escalate and the use of karyotyping could extend to women in the lower age bracket.
