Readers' Featured Comments/Questions - Late Preterm Birth and Abnormal Nuchal Translucency
Anonymous has left a new comment on your post "Late Preterm Birth - AGAIN":
I had a late preterm baby almost 4 months ago now. It was my first pregnancy, I was over 35, and developed high blood pressure. I don't think I realized the seriousness of delivering at 35 weeks until it was all over....believe me, I did not want to go early, but everything happened so quickly that I was stunned. My daughter was in the NICU in a major US hospital for 5 weeks, and came home on her due date...we still have cardiac and respiratory issues that we need to follow up on for her, but she appears to be a happy and relatively healthy 4 month old now.
She has doubled her weight since she has come home with us. I am afraid to see the costs associated with her NICU stay-it is scary to see hom many children enter the world and spend their first days weeks or months in a NICU. The census in the NICU our daughter was in hit 60 for weeks at a time. I am grateful that the technology exists to help our children, but also troubled by the number of newborns that need it.
To Anonymous Aug 31: Thank you for sharing your story. I know that you did not expect a response, but I also know many other readers will benefit from your comments and, perhaps, learn from your experience. It is hard enough when someone needs to be delivered early, as was your case, and still has a baby with complications of prematurity. But, we need to be super vigilant as patients and providers that we don't place a baby in the NICU as the result of a delivery that was unnecessary, performed early by miscaclculation of gestational age, or done for convenience as are at least 30% of 'late preterm' births. It is very important to understand that not all babies born at 34-38 weeks will do just fine. I am glad your daughter graduated from the NICU successfully (just having to stay that long in the hospital is a risky proposition in this day and age!)and I certainly hope she does well in the long-term. Again, thanks for reading and for sharing. Dr T

Dr, My husband and I went for an NT scan yesteday in Boston. The ultrasound tech and the doctor both measured out 7mm of fluid in our baby's neck. We met with the genetic counselor, and she informed us that based on everything, we have a 50% chance of there being a chromosomal issue, and 50% of there being nothing wrong. The heart has been strong since my first ultrasound at 8 weeks, and the doctor remarked at how the heart seemed to be functioning properly. I am scheduled for a CVS on Tuesday. I guess my question is - have there been children who have been diagnosed with an excess amount of fluid on the neck, and have gone on to be delivered healthy with no issues? I know the risks and I know that it's hard to be certain. My husband and I are trying to deal with this as honestly as possible, and we know what we will do if the prognosis from the CVS proves to be dire. Thanks!

To Jessica Sept 1: Did you have the NT done for any special reason, i.e., maternal age or previous pregnancy or family history of chromosomal problems, or simply as a routine study? Unfortunately, you do have at least a 50% chance of a baby with a chromosomal problem and/or a congenital heart abnormality. The prognosis for either of these problems will depend on the final diagnoses.
I am glad you are having the CVS done. That will answer the chromosomal question in most instances. However, even if this returns normal, your doctors might recommend that the baby have another study done during pregnancy or after birth to evaluate the possibility of mosaicism (two or more populations of cells, some chromosomally normal and some not. This will be especially important if any physical abnormalities are found. Also, the baby should have a very careful evaluation of its heart by 18-20 weeks, preferably, by a specialist in Maternal-Fetal Medicine, Pediatric Cardiology, or Radiology who has experience with the in utero diagnosis of congenital heart defects. The risk of a baby with a heart defect under these circumstances is proportional to the degree of NT width.
But the final answer to your question is this: YES, some babies with widened nuchal translucencies in first trimester end up being perfectly normal and with no apparent consequence of their 'abnormal' NT measurement. So, best of luck to you and your husband! Thanks for reading and please let me know how things turn out. I will be pulling for you guys - all three of you. Dr T

Hello Dr. T, before I call my Dr again, I thought I send this question for your thoughts:
I had a NT test yesterday.
1. The nasal bone was present -
2. The blood flow and heartbeat was normal
3. The skin behind the neck was a bit high - I was 3.6mm
4. My egg donor is 23 - I am 44.
I am Rh negative AND Sensitized with C and D deficiencies because of my last miscarriage and the blood transfusions I had UGH!!! My titers are very low and staying that way for now... which I'm told is good. My doctors are watching me like a hawk. I will be having blood work done every two weeks
for the titers and my OB and High Risk doctor visits will be every 4 weeks.
Two questions:
I will most likely have the Amnio test done to to be 100% sure. Besides the risk of miscarriage should I be worried of any blood problems because of my Rh neg/Sensitzed/C/D etc...with the Amnio test.
Secondly if the baby's heart beat was fine, and they give me a ratio that DS is low, what type of Cardio abnormalities could there be? I was told by my HR doc that if not DS it could be a cardio abnormality.
Thanks! Love your Blog it is so informative!

To Rebecca: Do you know if your egg donor is Rh-negative? If she was not, or if the sperm donor is not, then the baby has the chance of being Rh-positive. Under those circumstances, if during the amnio, some of the baby's blood gets into your circulation, it may act to "boost your immunity" just like a vaccine. In your case that may not be good! Regardless, you will be followed closely and the best way to evaluate the baby for evidence of anemia is by Doppler flow studies of the baby's middle cerebral artery looking for a significant rise in the peak systolic velocity. The typw of heart defects that lead to thickened NT measurements are, unfortunately, usually the more complex ones. There is no way I can go into detail in this response, but why don't we cross that bridge late on if something is actually found. Best wishes to you and please let us know how things develop! Dr T
