Patient's question:
Please ask if an NT value of 2.6mm without obvious thickening is okay? I am 25 years old. At 13 weeks for the check-up, the results showed the uterus size was 107.4×88.2×102.1mm, with a fetus echo seen in the uterine cavity. The spinal diameter was 71.7mm, the spine was faintly visible, the nasal bone was visible, fetal movement was visible, and the instantaneous fetal heart rate was 149 times per minute. The placenta was located on the anterior wall of the uterus, with a thickness of about 16.7mm, and the maximum depth of amniotic fluid was 41.3mm. The NT value was 2.6mm. The ultrasound showed normal-sized ovaries in the pregnant woman. The ultrasound suggests: single live fetus in the uterus at 13w3d, NT not obviously thickened, please combine clinical data, and it is recommended to re-examine. Please ask about my NT.Doctor's answer:
Analysis of the condition: NT thickening: Chromosomal abnormalities (such as trisomy 21, as well as triploidy, trisomy 13, trisomy 18, trisomy 22, 12p tetrasomy, etc., are also commonly associated with NT thickening), congenital cardiac structural malformations (congenital cardiac structural malformations are the most common non-chromosomal abnormality leading to NT thickening. Hyett et al. found NT thickening, and the incidence of cardiac and major vascular structural malformations increased. They recommended that early pregnancy NT measurement be used as an early screening indicator for fetal congenital heart disease.)
