Dr. Rochelson: Chromosomal problems of women in advance maternal age are the higher risk of having a baby with an extra-chromosomal, one chromosome missing and certainly if they had previous chromosomal abnormalities, the baby can be at risk as well. I wanted to show you one thing in terms of screening. We now are able to screen and pick up about 90% of Down Syndrome in about 11 weeks gestation and that is because these fetuses with Down Syndrome have a thick back of the neck and so what you see here is a cartoon on the right showing the measurement at the back of the neck and we can see that same thing by ultrasound at about 11 weeks which you can see in the picture on the left. And that is called Nuchal Translucency Screening. And again it is helpful or parents may choose to have that information so they can be prepared for the birth of the child that may have it.
