P13.19: Coronal measurement of fetal lateral ventricles: an ultrasonographic study

The aim of this study was to compare the diameter of the lateral ventricles measured by traditional axial view with novel measurement at the coronal plane. Prospective study of 144 fetuses in which sonographic measurements of the lateral ventricles using axial and coronal planes were performed at 19 to 38 weeks of gestational. 77 were evaluated as part of a routine fetal scan and 67 were referred for targeted scan. For each fetus, only the distal lateral ventricle's diameter was measured by the “classical” transventricular axial plane, whereas both ventricles were measured at the posterior coronal plane at the level of the atria using transfontanellar approach. The mean gestational age was 27.7 ± 4.6 weeks. A good visualization of both ventricles was achieved in 91% of the cases using the coronal plane. In the entire study group, the mean width of the distal lateral ventricle on the axial plane was 7.9 ± 1.9 mm versus 8.2 ± 1.9 mm on the coronal plane [p-value < 0.001]. The mean axial width was 6.6 ± 1.1 mm in patients who came for a routine scan, versus 9.3 ± 1.6 mm in patients who were referred for a neurosonogram [p-value < 0.001]. Our study showed that Coronal measurement of both proximal and distal ventricles are feasible, which is advantage over the axial view in which only the distal ventricle is clearly visible and measurable.
