EP08.03: The first trimester fetal ventricular system: validating three-dimensional ultrasonography with embryology

Prenatal diagnosis of pentalogy of cantrell with craniorachischisis by three-dimensional ultrasonography in the first trimester.

Assessment of fetal malformations in the first trimester of pregnancy by three-dimensional ultrasonography in the rendering mode. Pictorial essay.

We present our experience in the contribution of three-dimensional ultrasonography, using the rendering mode, to the prenatal diagnosis of congenital anomalies including neurological defects (acrania/anencephaly, encephalocele, holoprosencephaly), facial anomalies (cyclopia and facial clefts), abdominal wall defects (omphalocele and gastroschisis) and defects of extremities (fetal muscle-skelet...

First trimester ultrasonography in screening and detection of fetal anomalies.

An obstetrical ultrasound examination provides invaluable information regarding the fetus. Until the mid-1980s, ultrasound in the first trimester was limited to localization of the pregnancy, establishing viability, and accurate dating. With the advent of high-resolution ultrasound and transvaginal scanning, a significant amount of information about the fetus can be gained and provided to the p...

Prenatal Diagnosis of Ectrodactyly in the First Trimester by Three-Dimensional Ultrasonography.

Introduction Ectrodactyly, also known as split hand/foot malformation, is a rare developmental abnormality of the limbs that consists of absent central digits, a deep median cleft, and fusion of the remaining lateral digits, ultimately producing clawlike extremities. This case represents one of the earliest reported diagnoses of this anomaly to utilize three-dimensional (3D) ultrasonography. Ca...

Three-dimensional Ultrasonography in the Evaluation of the Fetal Cerebellum*

For the last years three-dimensional ultrasonography has become an imaging diagnosis method of great importance in obstetrics. One of its advantages would be the higher sensitivity compared with two-dimensional ultrasound in the diagnosis of some fetal malformations. The potential applications of this new method would be an improved accuracy in the measurement of fetal organs, the possibility o...
