BACKGROUND To predict success of endoscopic third ventriculostomy (ETV) in patients with obstructive hydrocephalus, we evaluated pre- and post- operative phase-contrast cine magnetic resonance images (PC MRI) on cerebrospinal fluid (CSF), cine flow in basal cisterns around the brain stem, and cervical medullar junction (CMJ) retrospectively. METHODS The study involved 102 patients with mean a...

PURPOSE To evaluate sonographic criteria for the diagnosis of subarachnoid, and particularly cisternal, hemorrhage in the preterm infant. METHODS The subarachnoid cisterns were studied on cadaveric anatomic sections and on postmortem ultrasonograms, as well as on in vivo ultrasonograms of healthy neonates. Based on the normal ultrasound appearances of these cisterns, criteria were developed f...

C-terminals on motoneurons are defined as those accompanied by characteristic postsynaptic specializations termed subsurface cisterns. We have previously shown, by light microscope immunolabelling methods, that subsurface cisterns occur regularly beneath choline acetyltransferase- and acetylcholinesterase-containing boutons on motoneurons. In the present study, the cholinergic nature of C-termi...

BACKGROUND Lack of access to safe and secure water is an international issue recognized by the United Nations. To address this problem, the One Million Cisterns Project was initiated in 2001 in Brazil's semi-arid region to provide a sustainable source of water to households. The objectives of this study were to determine the 30-day period prevalence of diarrhoea in individuals with and without ...

BACKGROUND AND PURPOSE The purpose of this study was to investigate the effect of nicardipine prolonged-release implants (NPRIs) on cerebral vasospasm and clinical outcome after severe subarachnoid hemorrhage. METHODS Thirty-two patients with severe subarachnoid hemorrhage and undergoing aneurysm clipping were included into this single center, randomized, double-blind trial. Sixteen patients ...

Lymphangioma circumscriptum is a congenital lymphatic malformation that results in gradual dilatation of lymphatic vessels and development of lymphatic cisterns. The treatment of choice is radical surgery. Other treatment methods including cryotherapy, sclerosing agent injections, radiation therapy and CO2 laser were suggested. We report successful treatment of a 14-year-old boy affected with l...

Normal imaging of cerebrospinal fluid (CSF) flow in the primate Macaca mulatta 99m using Tc labeled human serum albumin shows flow from the basal cisterns over the cerebral cortex in 4 hours. Anatomical correlation of basal cisterns with cisternographic images was demonstrated with latex casts of the normal CSF spaces. Cisternographic images from nonhuman primates with experimental communicatin...

Results The CT images in each patient revealed diffuse hyperdensity in the basal cisterns in an appearance similar to aneurysmal SAH. None of the patients had the typical distribution of nonaneurysmal perimesencephalic-SAH. In two of the patients, the prospective CT interpretation by the radiologist cited true SAH as the etiology of this increased attenuation within the subarachnoid spaces. In ...

We evaluated the use of a bypass between the middle meningeal artery (MMA) and P2 segment of the posterior cerebral artery (PCA) as an alternative to an external carotid artery (ECA-to-PCA) anastomosis. Five adult cadaveric heads (10 sides) were used. After a temporal craniotomy and zygomatic arch osteotomy were performed, the dura of the floor of the middle cranial fossa was separated and elev...
