Prediction of low birth weight infants from ultrasound measurement of placental diameter and placental thickness
Abstract
Background: The aim of the study was to help to predict low birth weight infants by measuring placental diameter and thickness.
Subjects and methods: A prospective study was conducted of 70 consecutive singleton pregnancies to evaluate placental diameter and thickness by ultrasonographic measurement at 36 weeks gestation. The individual data were fitted to a logistic regression analysis.
Results: A "warning limit" of a placental diameter of 18 cm and placental thickness of 2 cm at 36 weeks gestation were calculated to predict low birth weight infants.
Conclusion: Ultrasonographic placental diameter and thickness measurements appears to be of prognostic value in identifying the subsequent occurrence of fetal growth retardation.
