Sonographic Assessment of Normal Fetal Cerebral Lateral Ventricular Diameter at Different Gestational Ages

ABSTRACT

Abnormal dilatation of ventricles has been shown to be the most common abnormality of the brain & fetus in most of the geographical zones, but the normal dimension of the fetal lateral ventriclein south-southgeopolitical zones of Nigeria has not been evaluated.The aim of this study was to determine the normal feto-lateral ventricular diameter using ultrasound at different gestational ages. Measurement of the fetal-lateral ventricular diameter was obtained from 685 fetuses of pregnant mothers that met the inclusion criteria during routine ultrasound scan in Calabar metropolis. Measurement of the ventricular diameter was taken at the levelof the atria, measured according to Australian society for ultrasound in medicineguidelines.Original ResearchArticle
