The aim of the present study was to examine the changes of inflammatory and coagulation factors in blood of the internal jugular vein, not of peripheral vein, in patients with subarachnoid hemorrhage (SAH). The results show that while interleukin-6 (IL-6) and platelet activating factor (PAF) concentrations increased within first 4 days after SAH and(More)
This report describes a preoperative simulation and intraoperative localization system for use with three-dimensional functional images in intracranial surgery. The system, which produces three-dimensional functional images by superimposition of the generators of somatosensory evoked potentials derived from dipole tracing, was applied in the preoperative(More)
Brain temperature was measured at various depths beneath the pial surface in patients with hydrocephalus of varying aetiology. Temperature increased gradually with depth in all patients, with the highest temperature found in the ventricle. The difference between intraventricular and rectal temperatures (delta v-r) was greater in patients who underwent(More)
Moyamoya formations at the base of the brain are not congenital vascular malformations but represent collateral pathways associated with chronic progressive stenosis of the carotid fork. The authors have studied 44 personal cases, 18 children under 15 years of age, and 26 adults. In children the Moyamoya vessels change through six stages: (1) carotid fork(More)
Percutaneous transvenous embolization is one of the most effective treatments of intracranial dural arteriovenous fistulas (AVFs) involving the dural sinuses. We present a unique case of surgical transvenous embolization in a 48-year-old man with a dural AVF of the cavernous sinus who presented with intracerebral hematoma. The dural AVF drained only into(More)
OBJECT The goal of this study was to evaluate the efficacy of direct packing of the isolated sinus (occluded both distally and proximally) in patients with dural arteriovenous fistulas (AVFs) of the transverse-sigmoid sinus. METHODS Eight patients were included in this study. There were seven men and one woman, ranging in age from 47 to 75 years (mean(More)
A case is reported of acoustic neurinoma unrelated to Von Recklinghausens' disease in a child. A 14-year-old boy had suddenly become aware of impaired hearing associated with tinnitus, in August, 1988. He was admitted to our department in October, 1988. On admission, he had no neurological deficits except for right tinnitus. Acoustic tumor was found on air(More)
No marker that predicts accurately the time of occurrence of cerebral vasospasm due to subarachnoid hemorrhage (SAH) has been reported. In the present study, membrane-bound tissue factor (mTF) and myelin basic protein (MBP) concentrations in cerebrospinal fluid (CSF) were evaluated as a predictor of the time of occurrence of cerebral vasospasm. The mTF and(More)
OBJECT It has been suggested that nuclear factor (NF)-kappaB, a pleiotropic transcription factor, controls cell proliferation. The authors examined NF-kappaB activity and its participation in the growth of human malignant astrocytoma. METHODS The authors examined NF-kappaB activity in human malignant astrocytoma cell lines and high-grade astrocytoma(More)
