Hello doctor, I am a 33 year old female, who has a 5 year old baby girl. I had two miscarriages, one two years back at 11 weeks, and one last year at nine weeks. Now, I am three months pregnant, and I had a NT scan, which showed a thickness of 3 to 5 mm. Is this a case of high-risk pregnancy? Does it show any abnormality? Please let me know.
Hi. How are you doing? Let me put forth few facts. Your age is in normal limits and not in high-risk for anomalies or genetic problem. Only after 37 to 40 years it is high-risk. You do not seem to have any medical complications. You have one 5 year old child, so the chance of next healthy pregnancy is very high, both of you have proved your capability to have children. I know you had two bad incidents, but accidents do occur. Let me explain about NT (nuchal translucency), it shows the thickness behind the neck of the baby, which indirectly increases when baby has a genetic problem, we use it to screen for Down's syndrome, also called Mongolism or Trisomy 21. It can also diagnose problems like cardiac problems, musculoskeletal and lymphatic abnormalities in the baby. Since the baby's growth is matching with gestational age, only Down's syndrome has to be thought. Hopefully, with God's grace, I am sure the reading will be normal and your pregnancy will proceed normally. Hope I have clarified your query, do write back. All the best.
