Abstract:We performed 77 Doppler blood flow studies of the umbilical artery in 45 foetuses with malformations and/or chromosomal abnormalities. 20 foetuses had chromosomal abnormalities and 34 records of the second and third trimester were analysed. In 25 foetuses with malformations, but without chromosomal abnormalities, 43 investigations were performed between 21st and 40th weeks of gestation. In the second trimester, 3 of 11 foetuses with chromosomal abnormalities had an absence of enddiastolic flow velocities, wher… Show more

The basic purpose of prenatal fetal monitoring in the situation of hindered fetal growth with chronic hypoxia is to predict the phase of decompensation and to terminate pregnancy before it is developed. The major problem is in great individual variations at the moment of development of decompensation phase, so the major obstetric aim in the monitoring of the fetus hindered in growth is to determine the optimal time and way of delivery.

Fetuses with trisomy 21 often present with elevated UA PI in the late second or third trimester, irrespective of small for gestational age growth, malformations or histopathological findings of impaired placentation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
