BACKGROUND To investigate the value of prenatal diagnosis in fetal ultrasound abnormalities. METHODS Amniotic fluid samples of pregnant women who underwent invasive amniocentesis for ultrasound examination suggestive of fetal ultrasound structural abnormalities and soft markers of abnormalities during pregnancy from January 2016 to June 2021 at the Prenatal Diagnostic Center of Putian College Hospital were collected for amniotic fluid cell culture and G manifest band karyotype analysis. RESULTS (1) Most pregnant women with ultrasound abnormalities were delivered at the age of 23 to 32 years. (2) There were 66 cases of abnormal karyotype with an abnormal incidence of 9.64% (66/685), with chromosomal number abnormalities predominating. (3) Fetal ultrasound abnormalities are mainly soft markers of abnormalities. (4) The comparison of ultrasound abnormalities in the low and high maternal-fetal age groups was not statis-tically significant. CONCLUSIONS (1) Fetal ultrasound abnormalities are mainly soft markers of abnormalities. (2) The rate of fetal chromosomal abnormalities was the highest among the soft ultrasound indicators with NT thickening. (3) The incidence of fetal ultrasound abnormalities did not increase with increasing age. There was no statistical difference in the incidence of chromosomal abnormalities between the low age group and the high age group. (4) Fetal ultrasound testing provides a scientific and accurate basis for clinical heritage counseling and rebirth counseling, especially for chromosomal aneuploidy number abnormalities.
