Sonography of ventricular size and germinal matrix hemorrhage in premature infants.
Using the anterior fontanelle as an acoustic window, high resolution gray scale sonography brain scans with mobile apparatus were obtained in 35 premature infants. The sonographic technique provided accurate assessment of ventricular size and detected the subependymal germinal matrix and intraventricular hemorrhages. Ventricular size measurements correlated closely with computed tomography (CT)...
متن کاملRisk Factors of Germinal Matrix Intraventricular Hemorrhage in Premature Infants
OBJECTIVE To determine whether some clinical parameters can be used to predict the hemorrhage and whether the relationship between these clinical variables and the grades of hemorrhage is linear. METHODS A total of 230 premature infants, born at a gestational age less than 34 weeks were retrospectively reviewed. Germinal matrix-intraventricular hemorrhage (GM-IVH), the grade of the hemorrhage...
متن کاملPaucity of pericytes in germinal matrix vasculature of premature infants.
Germinal matrix (GM) is a richly vascularized collection of neuronal-glial precursor cells in the developing brain, which is selectively vulnerable to hemorrhage in premature infants. It has rapid angiogenesis associated with high levels of vascular endothelial growth factor (VEGF). Because pericytes provide structural stability to blood vessels, we asked whether pericytes were fewer in the GM ...
متن کاملCaudothalamic groove: value in identification of germinal matrix hemorrhage by sonography in preterm neonates.
A prospective study of 25 consecutive premature infants under 1,500 g was undertaken to evaluate the frequency and sonographic appearance of subependymal germinal matrix hemorrhage. In all 12 sonographically positive cases, the hemorrhage was initially imaged in the area immediately anterior to the caudothalamic groove. Special attention to this area permits early detection of germinal matrix h...
متن کاملGerminal matrix hemorrhage-intraventricular hemorrhage: pathogenesis and outcomes
Germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) is one of the CNS injuries affecting preterm infants occurring in about 15%–20% of subjects weighing less than 1500 g. Currently, using ultrasonography, we recognize three grades of GMH-IVH. Grade I involving the subependymal parenchyma and/or extending in less than 10% of the ventricle, grade II with intraventricular bleeding not...
