Can congenital biliary atresia be detected during prenatal examinations?

Congenital biliary atresia can generally be detected during prenatal examinations. The detailed analysis is as follows:

Congenital biliary atresia is a progressive disease affecting the intrahepatic and extrahepatic bile duct systems in newborns and is considered a genetic disorder. If a fetus has congenital biliary atresia, it can usually be identified during routine prenatal screening using four-dimensional color ultrasound (4D ultrasound). 4D ultrasound is a medical imaging technology that provides clear, real-time color images. It allows comprehensive and multi-angle visualization of the fetus's appearance, facial features, and organ development. As one of the most accurate methods for early diagnosis of fetal congenital surface abnormalities and congenital heart diseases, it can effectively detect congenital biliary atresia.

If congenital biliary atresia is confirmed during prenatal examination, it is recommended to seek timely medical consultation and, under the guidance of a physician, choose appropriate management options.
