Rheologia in ductus venosus metoda predictivă utilă pentru evoluția neonatală

Abstract

Many prenatal tests aim to predict foetal hypoxia and perinatal poor outcome. They are more or less invasive. The huge development of the ultrasound equipment opens many doors for the foetal examination. Among hose the foetal umbilical and portal vessels scan using Doppler shift is very useful for predicting the fetal status. The waves shape in the foetal ductus venosus (DV) can select those foetuses at risk for hypoxia. Our study’s aim is to evaluate the efficiency of that test for detecting poor perinatal outcome. 231 pregnancies were evaluated from the circulations in DV point of view. Abnormal shapes of the Doppler waves were correlated with poor perinatal outcome in 95.7% cases. The risk to have an Apgar score less than 7 at birth was 11.69 times greater for the babies with abnormal circulation in DV.
