VP44.02: Accuracy of ultrasound‐based prenatal scoring system for placenta accreta spectrum disorders

Abstract

Virtual poster abstractsConclusions: In this study we assume that if the decrease of PI-CMA is a consequence of a mild hypoxia which accompanies prolonged pregnancy, the decrease of PI-UA, especially in large fetuses, may be a sign of covert cardiac function deterioration. In such situations normal CPR does not indicate the satisfactory fetal condition. An assessment of the type of AoI blood flow velocity waveforms is a valuable adjunct to current fetal surveillance protocols used in the prolonged pregnancy. Such dynamics of changes in Doppler tests requires also an expert assessment of the fetal and neonatal cardiac function before delivery and postpartum.
