Preterm neonates with a very low birth weight of less than 1,500 g are at increased risk for developing intraventricular hemorrhage (IVH). Progressive ventricle dilatation of IVH patients may cause increased intracranial pressure, leading to neurological damage, such as neurodevelopmental delay and cerebral palsy. The technique of 3D ultrasound (US) imaging has been used to quantitatively monitor the ventricular volume in IVH neonates, which may elucidate the ambiguity surrounding the timing of interventions in these patients as 2D clinical US imaging relies on linear measurement and visual estimation of ventricular dilation from a series of 2D slices...

INTRODUCTION: Current ACOG technical bulletin #144, 2014 states "Women with monoamniotic twin gestations should undergo cesarean delivery to avoid an umbilical cord complication of the nonpresenting twin at the time of the initial twin's delivery." To assess feasibility of vaginal delivery, we compared neonatal outcomes after attempted VD versus planned cesarean delivery (CD). METHODS: This retrospective cohort study from 2 tertiary-care centers, reviewed all viable MoMo twin pregnancies beyond 24 weeks gestation, delivered over last 15 years...

Due to the possibility to examine at the patient bedside or incubator, ultrasound imaging of the central nervous system, particularly through the anterior fontanelle, is the most common diagnostic examination performed in neonates and infants with neurological problems. Despite its common application, this method has certain limitations. These limitations are associated with cross-sections of the cerebral structures that can be obtained when examining through the anterior fontanelle. The aim of the paper was to assess the usefulness of three dimensional sonography of the central nervous system in neonates and infants in the assessment of intracranial bleeding and its consequences when examined through the anterior fontanelle...

PURPOSE: Intraventricular hemorrhage (IVH) is a major cause of brain injury in preterm neonates. Three dimensional ultrasound (US) imaging systems have been developed to visualize 3D anatomical structure of preterm neonatal intracranial ventricular system with IVH and ventricular dilation. To allow quantitative analysis, the ventricle system is required to be segmented accurately and efficiently from 3D US images. Although semiautomatic segmentation algorithms have been developed, local segmentation accuracy and variability associated with these algorithms should be evaluated statistically before they can be applied in clinical settings...

Intraventricular hemorrhage (IVH) or bleed within the cerebral ventricles is a common condition among very low birth weight pre-term neonates. The prognosis for these patients is worsened should they develop progressive ventricular dilatation, i.e., post-hemorrhagic ventricle dilatation (PHVD), which occurs in 10-30% of IVH patients. Accurate measurement of ventricular volume would be valuable information and could be used to predict PHVD and determine whether that specific patient with ventricular dilatation requires treatment...

Germinal matrix intraventricular hemorrhage (IVH) is the most common type of intracranial hemorrhage observed in preterm neonates. It is a precursor of poor neurocognitive development, cerebral palsy, and death. The pathophysiology is not well defined, but damage to the fragile germinal matrix vasculature may be due to free radicals generated during inflammation and as a consequence of ischemia followed by reperfusion. Assessment of the oxidative stress status in these infants is therefore important. Urinary allantoin concentration was measured in preterm neonates as a marker of oxidative stress associated with IVH...

Intracerebral haemorrhage (ICH) occurring during pregnancy and the puerperium is an infrequent but severe complication with a high mortality and poor prognosis. Until recently, previous studies have mainly focused on the effect of different treatments on prognosis. However, few studies have provided solid evidence to clarify the key predisposing factors affecting the prognosis of ICH. In the present study, based on a unique sample with a high ICH incidence and mortality rate, we described the main clinical characteristics of ICH patients and found that the prognosis of patients who underwent surgical intervention was not better than that of patients who received other treatment modalities...

OBJECTIVE: The purpose of this study was to determine whether planned vaginal delivery is associated with increased risk of perinatal death and morbidity in twin pregnancies that are complicated by a very low birthweight of the second twin. STUDY DESIGN: We conducted a retrospective cohort study of twin pregnancies in which the second twin's birthweight was ≤1500 g. One hundred ninety-three twin gestations met the study criteria; patients were classified into 2 groups according to the planned mode of delivery: (1) cesarean delivery (n = 142) and (2) vaginal delivery (n = 51)...

BACKGROUND: Up to 40% of infants with persistent pulmonary hypertension (PPHN) remains refractory to conventional therapies, and extracorporeal membrane oxygenation (ECMO) is offered as an effective support for this group. However, ECMO is a highly invasive and risky procedure with devastating complications such as intracranial hemorrhage (ICH). In this study, we aimed to determine the risk factors for ICH in infants with PPHN. METHODS: A case-control study of patients admitted to the pediatric intensive care unit (PICU) with PPHN requiring ECMO support was conducted...

A three-dimensional (3-D) ultrasound (US) system has been developed to monitor the intracranial ventricular system of preterm neonates with intraventricular hemorrhage (IVH) and the resultant dilation of the ventricles (ventriculomegaly). To measure ventricular volume from 3-D US images, a semi-automatic convex optimization-based approach is proposed for segmentation of the cerebral ventricular system in preterm neonates with IVH from 3-D US images. The proposed semi-automatic segmentation method makes use of the convex optimization technique supervised by user-initialized information...
