Two-Dimensional Ultrasound Evaluation of the Fetal Cerebral Aqueduct: Improving the Antenatal Diagnosis and Counseling of Aqueductal Stenosis

Abstract

Our study demonstrated that it is possible to visualize and measure the cerebral aqueduct directly through a 2D ultrasound median plane. In fetuses with severe ventriculomegaly, the morphology and width of this structure could represent a relevant tool in improving AS diagnosis, differentiating it from other causes of significant ventricular dilation that carry a different outcome.
