Fetuses with trisomy 21 having conflicting findings on antenatal testing for fetal well-being.
OBJECTIVE
This series reports 3 cases with conflicting antenatal sonographic findings: intrauterine growth restriction, absent or reversed end-diastolic flow in umbilical artery Doppler imaging, and reassuring biophysical test results.


METHODS
We conducted a retrospective review of medical records.


RESULTS
Three fetuses had intrauterine growth restriction and absent or reversed end-diastolic flow in umbilical artery Doppler studies, but the biophysical test results and amniotic fluid volume assessment were normal. We found no other signs of fetal jeopardy from placental insufficiency. In these cases, trisomy 21 was established after birth by karyotyping. Ventricular septal defects and aortic regurgitation were noted in 2 of the 3 affected fetuses.


CONCLUSIONS
When there is an unusual combination of antenatal sonographic findings such as presented here, fetal cardiac abnormalities and aneuploidy should be considered.
