Rapid reduction of acute subdural hematoma and redistribution of hematoma: case reportArata Watanabe
Department of Neurosurgery, Faculty of Medicine, University of Yamanashi, Chuo, Yamanashi, Japan
Neurol Med Chir (Tokyo) 50:924-7. 2010..The present case illustrates that rapid spontaneous reduction of ASDH may occur by redistribution of hematoma, mainly to the supratentorial subdural space because of brain atrophy...
Bony carotid canal hypoplasia in patients with moyamoya diseaseArata Watanabe

Internal carotid artery occlusion manifesting only as oculomotor nerve palsyArata Watanabe
Department of Neurosurgery, Faculty of Medicine, University of Yamanashi, Chuo, Yamanashi, Japan
J Stroke Cerebrovasc Dis 17:433-5. 2008..Distal blood flow was compensated through an anastomosis from other arteries. Ischemia of the oculomotor nerve was thought to be caused by loss of supply from branches arising from the occluded cavernous portion of the ICA...
Diagnostic value of spinal MR imaging in spontaneous intracranial hypotension syndromeA Watanabe
Department of Neurosurgery, Faculty of Medicine, University of Yamanashi, Chuo, Yamanashi, Japan
AJNR Am J Neuroradiol 30:147-51. 2009..SIH is believed to be caused by CSF leakage from the spinal dural sac, whereas the usefulness of MR imaging of the spine remains unclear. Our aim was to elucidate the diagnostic value of brain and spinal MR imaging..
Effect of intracranial pressure on the diameter of the optic nerve sheathArata Watanabe
Department of Neurosurgery, Faculty of Medicine, University of Yamanashi, Chuo, Yamanashi, Japan
J Neurosurg 109:255-8. 2008..The authors investigated the relationship between subdural pressure measured at the time of surgery and ONS diameter measured on MR images in patients with chronic subdural fluid collection...
Decreased diameter of the optic nerve sheath associated with CSF hypovolemiaA Watanabe
Department of Neurosurgery, Faculty of Medicine, University of Yamanashi, Chuo, Yamanashi, Japan
AJNR Am J Neuroradiol 29:863-4. 2008..We showed that the subarachnoid space is decreased in patients with CSF hypovolemia and the usefulness of this finding...
[Dilation of subarachnoid space around the optic nerve in a patient with subdural effusion: a case report]Tomoko Futaki
Department of Neurosurgery, Graduate School of Medicine and Engineering, University of Yamanashi, 1110 Shimokato, Chuo City, Yamanashi 409 3898, Japan
No Shinkei Geka 37:881-5. 2009..These findings suggest that the diameter of the optic subarachnoid space co-relates with the intracranial pressure, and may be an indication for increased intracranial pressure...
Subdural effusions in the posterior fossa associated with spontaneous intracranial hypotensionArata Watanabe
Department of Neurosurgery, Faculty of Medicine, University of Yamanashi, Japan
Can J Neurol Sci 33:205-8. 2006..CONCLUSIONS: Subdural effusions in the posterior fossa can be identified by T2-weighted axial MR imaging, and are useful for the diagnosis of spontaneous intracranial hypotension and for verifying the effectiveness of treatment...
[The association of age and tracer clearance determined radionuclide cisternography]Yasuhiro Asari
Department of Neurosurgery, Interdisciplinary Graduate School of Medicine and Engineering, University of Yamanashi, 1110 Shimokato, Chuo shi, Yamanashi 409 3898, Japan
Brain Nerve 62:165-71. 2010..These results indicate that age should be taken in account while establishing the reference values for tracer kinetics in normal individuals...
Effectiveness of an epidural blood patch for patients with intracranial hypotension syndrome and persistent spinal epidural fluid collection after treatmentToru Horikoshi
Department of Neurosurgery, Interdisciplinary Graduate School of Medicine and Engineering, University of Yamanashi, Japan
J Neurosurg 113:940-6. 2010..Magnetic resonance imaging may show a fluid collection in the spinal epidural space of patients with spontaneous intracranial hypotension syndrome (SIHS), but the chronological changes remain unclear...
Unsuccessful tracer injection in radionuclide cisternography revisitedToru Horikoshi
Department of Neurosurgery, University of Yamanashi, Japan
Ann Nucl Med 20:333-6. 2006..Excessive tracer clearance from the body suggests such technical failure...
[Semi-quantiative RI cisternographic patterns in patients with chronic headache: a resemblance to those of intracranial hypotension syndrome]Toru Horikoshi
Department of Neurosurgery, University of Yamanashi, 1110 Shimokato, Tamaho-cho, Nakakoma-gun, Yamanashi 409-3898, Japan
No To Shinkei 58:51-6. 2006..In 3 patients who underwent post-treatment RI study, tracer kinetics was normalized. These findings may indicate that some of patients with chronic headache actually have CSF leakage that can be treated with epidural blood patch...
Expression of syndecans, a heparan sulfate proteoglycan, in malignant gliomas: participation of nuclear factor-kappaB in upregulation of syndecan-1 expressionArata Watanabe
Department of Neurosurgery, University of Yamanashi, Faculty of Medicine, 409 3898, Nakakoma gun, Yamanashi, Japan
J Neurooncol 77:25-32. 2006....
Quantification of thrombospondin-1 secretion and expression of alphavbeta3 and alpha3beta1 integrins and syndecan-1 as cell-surface receptors for thrombospondin-1 in malignant glioma cellsHirofumi Naganuma
Department of Neurosurgery, University of Yamanashi Faculty of Medicine, Nakakoma gun, Yamanashi, Japan
J Neurooncol 70:309-17. 2004..These results suggest that malignant glioma cells secrete high levels of TSP-1, which may be important in the migration of glioma cells via interactions with alphavbeta3 and alpha3beta1 integrins, and syndecan-1...
