Clinical Significance of Slightly Lateral Ventricular Enlargement in Healthy Infants

Minowa et al, J Matern Fetal Neonatal Med. 2016 Jul


OBJECTIVEThe aim of this study was to determine the clinical significance of slightly lateral ventricular enlargement.

METHODS 1,151 infants were examined with a gestational age of 36 weeks or greater. The presence of ventricular enlargement was assessed when apparent space was observed in the frontal horn or body of lateral ventricle by a transfontanel ultrasound scan.

RESULTS:Two hundred forty-eight infants had ventricular enlargement. The atrial widths in most infants were less than 10 mm. Ventricular enlargement correlated with Cesarean delivery, gestational age, birth weight, respiratory disturbance at delivery, and respiratory inhibition after crying (RIAC). Ventricular enlargement could be divided into three types by ultrasound findings. 

CONCLUSIONSSlightly lateral ventricular enlargement should be considered clinically significant.
