21-Three Body Syndrome Screening Risk Assessment and Its Explanation

A 4D ultrasound at 22 weeks of pregnancy revealed that the baby’s left brain posterior width is 0.45cm, while the right side is 0.55cm. No enlargement was found in both sides of the brain at 33 weeks; however, at 39 weeks, the left brain posterior width had increased to 0.66cm. How should this situation be handled?

At 32 weeks pregnant, if the baby’s femur length is below average, further examination may be needed to confirm normal fetal development.

If it is trisomy 16, it is recommended to terminate early pregnancy, and it is suggested that you consult with a professional regarding genetic counseling. Maintain a good work and rest routine, and increase physical exercise regularly to enhance your body’s resistance and immunity.
