Analysis on the ultrasonic manifestations of fetuses with chromosomal aneuploidy abnormality in second trimester of pregnancy

Objective:To analyze the ultrasonic manifestations of fetuses with chromosomal abnormality in second trimester of pregnancy,provide some clues for the diagnosis of fetal chromosomal abnormality. Methods:The ultrasonic manifestations of 49 fetuses with chromosomal abnormality in second trimester of pregnancy were analyzed retrospectively. Results:Among 49 fetuses with chromosomal aneuploidy abnormality,72 fetuses were found with abnormal ultrasonic manifestations,30 fetuses were found with abnormal morphology and structure,18 fetuses were found with ultrasonic soft indexes,6 fetuses were combined with abnormal structure,7 fetuses were not found with apparent abnormality. Conclusion:Most of the fetuses with chromosomal aneuploidy abnormality in second trimester of pregnancy have abnormal ultrasonic manifestations,including morphological abnormality and abnormal soft indexes,the phenomenon indicates that the possibility of chromosomal abnormality should be considered and corresponding genetic consultation should be provided when the fetuses are found with abnormal ultrasonic manifestations.
