The authors report the treatment of seven intracranial aneurysms in six patients with direct infusion of cellulose acetate polymer solution, a new liquid thrombotic material. These aneurysms were considered inoperable because of their size or location, or because of the patient's neurological condition. This material avoids the difficulties associated with(More)
A 34-year-old woman was admitted for the chief complaints of headache and blurred vision. She had bilateral papilledema and slight increase in CSF pressure (175mmH2O) with normal visual acuity and field. Neurological and hormonal examination were normal except for over response of PRL and TSH to TRH test. The sella was enlarged and MRI and metrizamide CT(More)
Cellulose acetate polymer solution is a liquid thrombotic material that hardens into the shape of an aneurysm into which it is injected. Therapy using this solution is a rapid technique that helps prevent the rupture of aneurysms, especially those that extravasate contrast material during angiography in the acute stage of subarachnoid hemorrhage. Using this(More)
Twenty-eight patients with spontaneous carotid-cavernous sinus fistulas (CCFs) were treated using a variety of techniques. Three of four patients with direct CCFs underwent intravascular embolization with a detachable balloon. Embolization with polyvinyl alcohol particles through an external carotid endoarterial route was used in six patients with indirect(More)
Moyamoya syndrome is defined as the development of collateral anastomosis pathways at the base of the brain, associated with chronic progressive stenosis of the carotid fork. Both reconstructive vascular surgery and conservative strategies are used to treat this syndrome, but the latter cannot prevent the disease from progressing. We describe the procedure(More)
PURPOSE To elucidate the coronal plane locations of extraocular muscle (EOM) pulleys following torsional muscle surgery. DESIGN Case report. METHODS A 76-year-old man underwent advancement of the anterior part of the inferior oblique muscle to treat full macular translocation-induced incyclotropia. Postoperatively, magnetic resonance imaging was used to(More)
Cell therapy using stem cells is awaited by stroke patients with impaired movement and cognitive functions, although intravenous alteplase-administration ameliorated outcomes of patients receiving the therapy within 3 h of onset. In this study, we explored the therapeutic effects of neural progenitor cells (NPC) upon middle cerebral artery occlusion (MCAO)(More)
The authors have developed a liquid material for thrombosing aneurysms. This material is a mixture of cellulose acetate polymer and bismuth trioxide dissolved in dimethyl sulfoxide. On contact with blood, the dimethyl sulfoxide diffuses and cellulose acetate polymer forms, which balloons when slowly injected into the blood. The polymer solidifies from(More)
A patient with an olfactory neuroblastoma in the frontal skull base was treated with primary tumor excision and partial resection of the A2 segment of both anterior cerebral arteries (ACA's). Revascularization was carried out using a superficial temporal artery (STA) interposition graft between the proximal and distal stumps with A3 segment-to-A3 segment(More)
UNLABELLED We report on the successful identification of epileptic foci in two children with partial epilepsy using ictal magnetoencephalography (MEG). Case 1 is a 12-year-old male suffering with simple partial seizures with leftwards nystagmus. Ictal SPECT revealed a hyperperfusion area in the right lateral occipital area, and MRI revealed cortical(More)
