BACKGROUND The causes of bronchopulmonary dysplasia (BPD) are multifactorial. Overdistension of the lung (volutrauma) is considered an important contribution. As an alternative to traditional pressure-limited ventilation (PLV), modern neonatal ventilators offer modes which can target a set tidal volume. OBJECTIVES To determine whether volume-targeted neonatal ventilation, compared with PLV, r...
OBJECTIVE Using an evidence-based approach, a Vermont Oxford Network focus group whose goal was to reduce brain injury developed and implemented a number of potentially better practices. Each center approached implementation of the practices differently. Reducing the incidence of intraventricular hemorrhage and periventricular leukomalacia are important for improving long-term outcomes for low ...
This study was conducted to determine the incidence of cerebral injury as detected by postnatal brain scan in monochorionic twins with selective intrauterine growth restriction. Having excluded cases complicated with twin-to-twin transfusion syndrome and one co-twin suffering intrauterine fetal death, a total of 73 monochorionic twin pregnancies divided into absence (group I, n = 46) or presenc...
Twenty-four patients with ventricular septa are discussed. Seventeen patients had septa acquired during the neonatal period and seven exhibited septations at birth (cogenital septa). Among the acquired septa, there were true intraventricular septa and septa that originated outside the ventricles but later became part of the ventricular system (pseudosepta). Pseudosepta originate in necrotic, ca...
Magnetic resonance imaging (MRI) has proved to be a valuable tool for monitoring development and pathology in the preterm brain. This imaging modality is useful for assessing numerous pathologies including periventricular leukomalacia, intraventricular haemorrhage/germinal layer haemorrhage, and periventricular haemorrhagic infarction, and can help to predict outcome in these infants. MRI has a...
Recent findings point to the existence of a cortical-subcortical parietal network that drives attention-related integration of features and elements. Here we ask whether the functioning of this network might be modulated by early periventricular lesions. To this end, a cohort of adolescents who were born premature with different severity of bilateral periventricular leukomalacia (PVL) and two g...
There is a high incidence of periventricular leukomalacia, caused by hypoxia-ischemia, in preterm infants. These lesions damage the periventricular crossroads of commissural, projection and associative pathways, which are in a close topographical relationship with the lateral ventricles. We explored to what extent abnormalities of echogenicity of the periventricular crossroads correlate with ch...
Eleven infants were encountered (nine premature, two term) in whom well-defined small periventricular cavitations were found by sonography in the first week of life. The sonographic findings bore remarkable similarity to subependymal pseudocysts in neonates previously described in autopsy specimens. The cavitations, which were identified predominantly along the superolateral aspects of the late...
