Clinical Significance of Slightly Lateral Ventricular Enlargement in Healthy Infants.

Minowa et al, J Matern Fetal Neonatal Med. 2016 Jul 18


OBJECTIVE: The aim of this study was to determine the clinical significance of slightly lateral ventricular enlargement.

METHODS: 1,151 infants with a gestational age of 36 weeks or greater, 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. Forty-five infants showed only enlargement of the anterior horn (Type A), 97 infants showed enlargement from the body to the posterior horn (Type B), and 108 infants showed whole enlargement from the anterior to the posterior horn (Type C). The infants with Type A correlated with intrauterine growth restriction, placenta previa, male gender, and birth weight. The infants with Type B correlated with Cesarean delivery. The infants with Type C correlated with diabetes mellitus, respiratory disturbance at delivery, RIAC, and feeding hypoxemia.

CONCLUSIONS: Slightly lateral ventricular enlargement should be considered clinically significant.
