Abstract

Aim of the work: To evaluate the role of the new placental score (PLS) by combining the Doppler umbilical artery score (blood flow classes, BFC) and the uterine artery score (UAS) to predict the pregnancy outcome in high risk pregnancy. Patients and methods: Forty pregnant ladies with high risk pregnancy were included in the study. The UAS and the BFC were combined to form a placental score (PLS) as an expression of general placental vascular resistance PLS = BFC + UAS, with figures in the range 0-7. Serial examinations were performed for each patient, in the 3d trimester. The results of last examination were related to the three perinatal outcome variables; premature birth, small for gestational age (SGA), and delivery by cesarean section (CS). Results: The relation between placental score and pregnancy outcome revealed - score (0) in 62.5% of patients, which was significant for CS (52%) followed by SGA + CS (28%) - score (I) in 20% of patients, was significant for CS (50%) and SGA (37.5%) - score (II) in 12.5% of patients, was mainly significant for preterm delivery + SGA (80%) - score (III) in 5% of patients, was highly significant for CS + preterm delivery (100%). Conclusion: The new PLS showed a better relationship to adverse perinatal outcome than the BFC and the UAS. The PLS can simplify evaluation of uteroplacental and fetoplacental Doppler velocimetry. © 2011 Egyptian Society of Radiology and Nuclear Medicine. Production and hosting by Elsevier B.V.
