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...
Severe cerebral intraventricular hemorrhage (IVH) in preterm infants continues to be a major clinical problem, occurring in about 15-20% of very preterm infants. In contrast to other brain lesions the incidence of IVH has not been reduced over the last decade, but actually slightly increased. Currently over 50% of surviving infants develop post-hemorrhagic ventricular dilatation and about 35% d...
Hydrocephalus is the most common developmental disability and leading cause of brain surgery for children. Current treatments are limited to surgical intervention, as the factors that contribute to the initiation of hydrocephalus are poorly understood. Here, we describe the development of obstructive hydrocephalus in mice that are null for Wrp (Srgap3). Wrp is highly expressed in the ventricula...
BACKGROUND AND PURPOSE Hypertension results in a spectrum of subcortical cerebrovascular disease. It is unclear why some individuals develop ischemia and others develop hemorrhage. Risk factors may differ for each population. We identify factors that predispose an individual to subcortical symptomatic intracerebral hemorrhage (sICH) compared with ischemia. METHODS Demographic and laboratory d...
Computed tomographic scans in 81 consecutive patients wih subarachnoid hemorrhage due to ruptured aneurysm were analyzed for patterns of hemorrhage and lucency and correlated with the development of spasm and hydrocephalus. The circulation time was measured angiographically in representative cases of spasm. Hemorrhage corresponded in a general way to the fossa of aneurysm origin and, when there...
BACKGROUND AND PURPOSE The purpose of this study was to determine whether leukoaraiosis (LA) predicts hemorrhagic transformation and poor outcome in patients with acute ischemic stroke treated by mechanical thrombectomy. METHODS We retrospectively analyzed patients with anterior circulation stroke treated with Merci devices and identified LA in the deep white matter (DWM) and periventricular ...
PURPOSE To review the cranial CT and MR examinations of 29 children with perinatally transmitted HIV infection and correlate the imaging findings with clinical and pathologic data. METHODS 28 children were examined with CT, four with MR. RESULTS CT abnormalities were seen in 25 children studied (89%), including cerebral atrophy (25 children), basal ganglia calcification (10 children), periv...
Doppler velocimetry of ductus venous in preterm fetuses with brain sparing effect: neonatal outcome.
OBJECTIVE to evaluate the relationship between ductus venous (DV) and Doppler velocimetry in neonatal outcome in severe compromised preterm fetuses. METHODS the study was designed as an observational and cross-sectional study with 52 premature neonates with brain sparing effect. The criteria of neonatal severe morbidity were: severe intraventricular hemorrhage (grades 3 or 4), retinopathy of ...
