Introduction
A routine B-ultrasound for minor anomaly screening generally examines whether the fetal organ systems are malformed. This type of B-ultrasound can assess fetal growth and development, placental function, amniotic fluid depth, umbilical cord around the neck, and the development of various organs and systems. It enables timely detection of fetal abnormalities, such as urinary and reproductive tract anomalies, gastrointestinal obstructions, etc., helping to identify problems early for prompt intervention and preventing serious outcomes.
B-ultrasound screening for minor fetal anomalies generally involves checking whether the fetal organ systems have any malformations. The specific details are as follows:
B-ultrasound screening for minor anomalies is typically performed around week 29 of pregnancy. This prenatal examination uses ultrasound equipment to evaluate the fetus's growth and development, placental function, amniotic fluid depth, presence of nuchal cord, and the development status of various organs and systems. It can timely detect fetal abnormalities such as urinary and reproductive tract defects, gastrointestinal obstructions, anencephaly, spina bifida, and congenital heart disease. Early identification helps enable prompt intervention and prevent serious outcomes.
After undergoing B-ultrasound screening for minor anomalies, if abnormalities are detected, a definitive diagnosis should be made under the guidance of a clinician, integrating patient history and results from other laboratory tests. In cases of severe abnormalities, termination of pregnancy may be considered.
