Chorionic Villus Sampling (CVS) (11-15 weeks)

Chorionic Villus Sampling is an invasive procedure used to diagnose chromosomal abnormalities, like Down’s Syndrome. It can also be used to detect various genetic syndromes e.g. Cystic Fibrosis. It is performed by one of our fetal medicine consultants under ultrasound guidance between 11 and 15 weeks of pregnancy.

Under local anaesthetic a fine needle is passed through the tummy and into the womb so that a sample of placental tissue can be obtained.

The tissue is sent to the laboratory for chromosome analysis and the rapid result is available within 48 working hours. As the procedure involves putting a needle into the womb, it carries a small risk (around 1%) of miscarriage.

 

Amniocentesis

Amniocentesis is an invasive procedure used to diagnose chromosomal abnormalities like Down’s Syndrome. It is performed by one of our fetal medicine consultants under ultrasound guidance and can be carried out from 15 weeks of pregnancy.

A fine needle is passed through the tummy and into the womb so that a small sample of fluid from around the baby can be obtained. The fluid is sent to the laboratory for chromosome analysis and the rapid result is available within 48 working hours. As the procedure involves putting a needle into the womb, it carries a small risk (around 1%) of miscarriage.

Second Opinion

Our fetal medicine consultants are highly skilled specialists who can provide a second opinion if you have any concerns about the health of your baby.
