Early identification of fetuses with chromosomal abnormalities enables health
care providers to form an appropriate management plan for each patient. The
main objective of this study was to determine the role of ultrasonography in screening
and identifying fetuses at risk for chromosomal abnormalities.
A retrospective review of 6480 patients from the Obstetrics and Gynecology
ward of Firouzgar hospital in Tehran was undertaken. Computer databases of
patients were correlated to compare the results of the fetal ultrasonographic examination
with the cytogenetic results from amniocentesis. Univariate and multivariate
analyses were used to determine the best correlations between ultrasonography
findings and chromosomal abnormalities.
Thirty-seven chromosomal abnormalities were found in 6480 fetuses (0.57%).
Down syndrome was the most common finding with trisomy 18 and 13 being the
next two most common abnormal findings. Multivariate analysis showed significant
correlations between anomalies of the central nervous system, heart, face
and neck, and extremities and increased nuchal fold, increased bowel echogenicity,
abnormal biparietal diameter to femur ratio and the presence of chromosomal
abnormalities (p value
