311 Predictive ability of cerebroplacental ratio for adverse perinatal outcome in the third trimester

Abstract

Introduction and aims: Fetal growth restriction is associated with increased risk of adverse perinatal outcome. The aim was to investigate the potential of cerebroplacental ratio (CPR) to predict adverse perinatal outcome in high-risk pregnancies in the third trimester. Another aim was to study if CPR has better predictive value than its components, middle cerebral artery (MCA) pulsatility index (PI) and umbilical artery (UA) PI. Methods: A register-based study including 1573 singleton high-risk pregnancies with Doppler examinations at 32+0 to 40+6 gestational weeks at two perinatal centers between 1994 and 2017.
