Middle Cerebral to Umbilical artery Doppler ratio and amniotic fluid volume measurement in postdated pregnancies

Abstract

Postdate pregnancy is defined as the one that persists for 41 completed weeks or more. Postdate pregnancies account for about 5 – 10 % of the deliveries and are known to be associated with increased risk for perinatal complications. Maternal risks of post-term pregnancies include increased operative delivery, postpartum hemorrhage and maternal puerperal infection. In addition, post-term pregnancies are associated with considerable psychological morbidity. The pregnancy is perceived by many women as becoming high risk once the estimated date of confinement is passed; this leads to increased maternal anxiety.
