In the neonate, ventriculitis and inflammatory infiltration of the choroid plexus usually accompany meningitis. Intracranial sonograms were reviewed from six infants referred for evaluation because of clinically suspected or confirmed ventriculitis. Findings included ventricular dilatation with irregularity of the ventricular margins and increased periventricular echogenicity. The choroid plexu...

Changes in ventricular size and brain parenchyma were documented in 40 preterm neonates with intracranial hemorrhage (ICH), who were serially examined for 3 weeks or more. Sonography disclosed a close relation between the severity of the intracranial hemorrhage and the development of progressive ventricular dilatation. Eighty percent of preterm neonates with minor degrees of intracranial hemorr...

Intraventricular diastolic right ventricular (RV) flow field dynamics were studied by functional imaging using three-dimensional (3D) real-time echocardiography with sonomicrometry and computational fluid dynamics in seven awake dogs at control with normal wall motion (NWM) and RV volume overload with diastolic paradoxical septal motion. Burgeoning flow cross section between inflow anulus and c...

1. The effect on rectal temperature of adrenoceptor blocking agents, injected through a cannula chronically implanted into a lateral cerebral ventricle, was examined in unanaesthetized rabbits, cats and rats, kept at room temperature (19-22 degrees C).2. In rabbits, the alpha-adrenoceptor blocking agent phenoxybenzamine (50 or 100 mug) produced marked hypothermia when injected intraventricularl...

The goal of this study was to compare the Spiegelberg intraventricular intracranial pressure (ICP)/intracranial compliance monitoring device, which features an air-pouch balloon catheter, with existing gold-standard methods of measuring ICP and intracranial compliance. A Spiegelberg intraventricular catheter, a standard intraventricular catheter, and a Codman intraparenchymal ICP microsensor we...

OBJECTIVE The objective of this study was to determine the effect of indomethacin on reducing the incidence of intraventricular hemorrhage in premature infants treated in our units at King Faisal Specialist Hospital and Research Centre. METHODS This historical cohort study included 45 infants born with birth weights of 1250g or less and received indomethacin in the first 12 hours of life for ...

Intraventricular hemorrhage (IVH) may occur as an isolated event from primary ventricular bleeding or as a complication of brain hemorrhage from another etiology. It is associated with high mortality and morbidity. The underlying risk factors include hypertension and aneurysms, among others. However, not all the exact etiologies are known. In this study, a case of a 24-year-old man who suffered...

To test the hypothesis that acute hypotension resulting from pneumothorax would be associated with severe brain injury (grade 3 or 4 intraventricular haemorrhage), 67 very low birthweight (VLBW) infants of 32 weeks' gestation or less with respiratory distress syndrome and pneumothorax were studied. Thirty six had pneumothorax associated with systemic hypotension and 31 had pneumothorax with nor...

OBJECTIVE The purpose of this paper was to investigate the role of two three-dimensional magnetic resonance (MRI) sequences: enhanced spoiled gradient recalled echo (SPGR), and fast imaging employing steady-state acquisition (FIESTA) in the evaluation of intraventricular neurocysticercosis cysts and scolices. METHOD Seven neurocysticercosis patients suspected of presenting intraventricular le...

The effects of synchronized direct current countershock on ventricular automaticity, intraventricular conduction, and atrioventricular conduction were studied before and after ouabain administration and after diphenylhydantoin. At the level of electrical energy that induced ventricular arrhythmias, averaging 159 watt-seconds, countershock transiently increased ventricular automaticity and prolo...
