I'm 16 weeks pregnant. At 12 weeks, we had a nuchal scan with a nuchal measurement of 6.8mm, which made us 1:2 risk of Down Syndrome. We had a CVS which has now cleared us for Downs and all the other chromosomal abnormalities that they look at. But because of the high nuchal reading, there is a high chance that there will be something wrong with the baby. We've been told there's only about a 30% chance it will be born alive and well. The most common problems seem to be cardiac related, but there's also a whole range of other problems that apparently coincide with a high nuchal reading.
We had a further scan at 15 weeks, and everything looked normal.
We've done some research ourselves and discussed the situation with the ultrasound doctor. But it is difficult to understand what the risks really are, as such a high reading seems very uncommon.
There is some suggestion that there is much less likely to be any problems if the 20 week scan and a heart scan at 24 weeks are normal.
Has anyone been in a similar position, or know anything about this? We're having a terrible time trying to come to a decision as to whether we should terminate -either now, or if further scans show a problem - or proceed with the pregnancy.
