Hi,

I have had experience with this. Unfortunately not with a good outcome. At the 12 week scan the nuchal measurement was 10mm which obviously was extremely bad. A CVS revealed no chromosomal abnormalities. There was a cystic hygroma on the back of the neck which was still there at the 19 week scan. At 19 weeks there was evidence of fluid in one lung but no other hydrops. There was no hydrops at the next scan at 25 weeks. However by 28 weeks severe hydrops had developed and the only option was to deliver early at 29 weeks. Unfortunately she survived only 3 hours as the hydrops had severely restricted lung development and no amount of medical support could get her lungs to inflate.

The problem with hydrops is it usually just keeps getting worse. In your case with it being detected at such an early stage the prognosis is probably not good. Sorry to tell you that.
