Question
After all the detailed checks like the four-dimensional ultrasound and the non-invasive prenatal test, everything was normal. Suddenly, during the late pregnancy, there was an excessive amount of amniotic fluid. Is there a high possibility of fetal malformation? Do I need to have an amniocentesis?
Answer
Based on the description from the pregnant woman, the amniotic fluid index is 32cm, indicating a sudden and continuous increase in amniotic fluid. This suggests that the fetus may have malformations, such as hydrocephalus or urinary system abnormalities. It is recommended to undergo amniocentesis for further examination. The non-invasive prenatal test mainly checks for conditions like trisomy 21 and neural tube defects, while the four-dimensional ultrasound primarily examines the development of the fetus’s heart and major organs. However, due to potential changes in fetal development over time, it cannot be completely ruled out that there may be malformations. It is recommended to have an amniocentesis to obtain more accurate information. Wishing you good luck.
