Prenatal diagnosis of placenta and umbilical cord pathologies by three-dimensional ultrasound: Pictorial essay

Abstract

The authors present their experience in prenatal diagnosis of placental and umbilical cord pathologies, using three-dimensional ultrasound (3DUS) in the rendering and tomography ultrasound imaging (TUI) modes, associated with color Doppler in some cases. Cases of placenta accreta/placenta previa, circumvallate placenta, succenturiate lobe, true knot of the umbilical cord, nuchal cord, and marginal/velamentous umbilical cord insertion are presented. 3DUS can contribute to improve the accuracy of prenatal diagnosis of placenta and umbilical cord pathologies.
