Ultrasound studies in preterm infants with hydrocephalus

Investigation of infant brain with or without hydrocephalous in our environment using anterior transfontanelle ultrasound scan

“…Graziani et al [7] conducted serial ultrasound studies of cerebral ventricular size on 40 small pre-term infants, 26 of whom were believed to be at risk of intracranial hemorrhage or hydrocephalus secondary to intracranial hemorrhage or both. Hydrocephalus was diagnosed by ultrasound study in 12 of the high-risk infants, eight of whom required a surgical shunt procedure because of progressive ventricular enlargement.…”

Frequency and cause of disagreements in imaging diagnosis in children with ventriculomegaly diagnosed prenatally

“…However, to our knowledge, there is no such definition for ventriculomegaly in the postnatal population. There are a wide variety of methods for characterizing neonatal ventricles using ultrasound including: the ratio of the distance from the falx to the lateral wall of the ventricle to the hemispheric width; the ratio of the ventricular diameter to the diameter of the brain at the same level; the displacement of the medial wall of the ventricle toward the midline; and subjective assessment15–26. Similarly, on neonatal MRI, ventricular size has been assessed using a ventricular/brain ratio27.…”

Neonatal intracranial hemorrhage and complicating hydrocephalus

“…progressive enlargement of the ventricles does not always occur and shunting is not always needed. 17 One review of the literature reported a 25% (range 6%-55%) incidence of progressive dilatation following intracranial hemorrhage.' In our series only two infants required surgical shunting for their hydrocephalus.…”
