OBJECT The purpose of this study was to evaluate an original neurofiberscope-guided strategy for the management of slit-ventricle syndrome that occurs after shunt placement. METHODS Between 1995 and 2003 15 patients with slit-ventricle syndrome (mean age 14.2 years) underwent endoscopic third ventriculostomy (ETV) and shunt removal. During the initial(More)
BACKGROUND Subarachnoid hemorrhage (SAH) often causes a prolongation of the corrected QT (QTc) interval during the acute phase. The aim of the present study was to examine independent risk factors for QTc prolongation in patients with SAH by means of multivariate analysis. METHOD We studied 100 patients who were admitted within 24 hours after onset of(More)
A 46-year-old man presented with right hemiparesis. Cranial magnetic resonance (MR) imaging revealed both an acute cerebral infarction in the territory of the left anterior cerebral artery (ACA) and a thin subarachnoid hemorrhage in the left superior frontal sulcus. MR angiography revealed stenosis at the A2 segment of the left ACA. MR cisternography was,(More)
OBJECT The authors report their investigation on the current status of neuroendoscopic biopsy for ventricular and paraventricular tumors as well as treatment for associated hydrocephalus in Japan. METHODS Patients who had undergone therapeutic neuroendoscopy between 2005 and 2009 were included in this study. The main items examined were age; sex;(More)
Progressive supranuclear palsy-Richardson's syndrome (PSP-RS) is a neurodegenerative disease characterized by postural instability and vertical gaze palsy, but the clinical diagnosis of PSP-RS is often difficult in the early stage of the disease. A 64-year-old male experienced frequent falls, followed by dysarthria and dysphagia. Neurological examination at(More)
OBJECTIVE Evaluation of results of the neurofiberscopic biopsy of tumors of the pineal region and posterior third ventricle. METHODS From 2001 to 2004, 23 patients (mean age, 30.6 yr) with tumors located in the pineal region or posterior third ventricle underwent neurofiberscopic biopsy with simultaneous third ventriculostomy. The procedure was indicated(More)
BACKGROUND We retrospectively analyzed factors related to the outcomes of patients with basilar artery occlusion. METHODS Twenty-eight patients with basilar artery occlusion admitted to our hospital within 24 hours after onset between April 2007 and December 2010 were included. We investigated parameters related to outcome, such as coexisting disease,(More)
PURPOSE We report a case of type 1 proatlantal intersegmental artery (PIA) associated with multiple anomalies of the aortic arch, and discuss the possible embryonic mechanism and clinical importance of the multiple cerebrovascular variants in this patient. METHODS A 65-year-old woman with dizziness underwent cerebral magnetic resonance (MR) imaging and(More)
We describe two recent cases of spontaneous intracranial hypotension. A 38-year-old woman developed a severe postural headache. Magnetic resonance imaging (MRI) showed marked dural enhancement. Histopathological findings of dural biopsy showed numerous dilated vessels in the dura, rather than hypertrophic change. Lumber CSF pressure was 5 cmH2O and RI(More)
The aim of this study was to assess the subcellular localization of basic fibroblast growth factor (bFGF) and fibroblast growth factor receptor 1 (FGFR1) in pituitary adenomas. We studied 61 patients who had primary pituitary adenomas and underwent operation. The immunohistochemistry for bFGF, FGFR1, and MIB-1 was examined in paraffin-embedded tissues. The(More)
