- W2065256906 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, whereas the other foetuses had pulsatility indices within the range for foetuses with a normal karyotype. In the third trimester, 7 of 10 foetuses with chromosomal abnormalities had pathological Doppler findings. Four cases had absent or reversed enddiastolic (ARED) flow velocities. Altogether 10 of 13 foetuses beyond the 19th weeks of gestation had pathological Doppler findings (sensitivity = 77%). The structure and the function of the placenta is influenced by the abnormal karyotype, which is demonstrated by pathological Doppler findings. Only 3 of 43 investigations in foetuses with malformations but normal karyotype, showed abnormal PI values and there was no case of ARED flow. In a group of 24 foetuses with ARED flow, 6 foetuses had chromosomal abnormalities. All foetuses with malformations and ARED flow had an abnormal karyotype. Prenatal chromosome analyses of foetuses with suspicious sonographic findings, revealed a rate of 29% chromosomal abnormalities, nearly all of them with a maternal age under 35 years. Whereas Doppler sonography cannot exclude chromosomal abnormalities before the 20th weeks of gestation, there is a good correlation between chromosomal abnormalities and abnormal Doppler findings later on.(ABSTRACT TRUNCATED AT 250 WORDS)" @default.
