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)
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)
BACKGROUND AND PURPOSE No marker that reflects and predicts brain injury due to subarachnoid hemorrhage (SAH) and cerebral vasospasm has been reported. We hypothesized that membrane-bound tissue factor (mTF) and thrombin-antithrombin III complex (TAT) in the cerebrospinal fluid (CSF) of patients with SAH become markers indicating brain injury. To evaluate(More)
gamma-Aminobutyric acid is synthesized by glutamic acid decarboxylase (GAD), which has two forms, GAD65 and GAD67. Genomic clones coding mouse GAD67 (mGAD67) have been isolated. The restriction map of the overlapping clones covers a region of more than 45 kb of genomic DNA. The mGAD67 gene contains 16 translated exons in addition to an exon which is(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)
We measured the distance between the infundibular recess and the tip of the basilar artery (BA) on midsagittal magnetic resonance (MR) images in 217 subjects (mean age, 54.7 years) without intracranial disorders and 8 patients with hydrocephalus treated neuroendoscopically. The mean distance measured in the 217 subjects without intracranial disorders was(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)
