We report a rare case of a ruptured dissecting anterior inferior cerebellar artery (AICA) aneurysm treated by endosaccular embolization with a Guglielmi detachable coil (GDC). An 85-year-old female presented with headache. Computed tomographic (CT) scan showed subarachnoid hemorrhage and intraventricular hemorrhage in the fourth ventricule. Cerebral(More)
We developed straight style transfer equipment for a person with disabled legs. It realizes travel in a standing position even on uneven ground, standing-up motion from a chair, and ascending stairs. This equipment comprises three modules: a pair of elastic crutches, a powered lower extremity orthosis, and a pair of mobile platforms. We show the conceptual(More)
Hemodynamic stress is considered one of the most important factors in the growth of cerebral aneurysms. The authors report a rare case of cerebral aneurysm located at the distal posterior cerebral artery (PCA) in which collateral circulation developed due to occlusion of the internal carotid artery (ICA). A 73-year-old male was admitted to our hospital with(More)
A 57-year-old female presented with a left petroclival meningioma fed by the meningohypophyseal trunk of the internal carotid artery (ICA). The enlarged tentorial marginal artery and inferior hypophyseal artery were successfully embolized with the TruFill DCS Detachable Coil System through a 0.019-inch inner diameter microcatheter. Superselective(More)
Intrasacral fixation technique devised by Jackson is said to provide rigid lumbosacral fixation. We treated 3 cases of lumbosacral lesions using this technique in which lumbosacral segment had become extremely unstable during surgical intervention adding to the effect of original lesions. In all cases, surgeries were performed in 2 stages, intrasacral(More)
The authors reviewed their clinical experience with preoperative embolization of metastatic spinal tumors. Between October 2000 and September 2003, 20 patients (13 men and 7 women; average age 68.3 years, range 44-82 years) underwent 24 spinal operations for 22 spinal metastatic tumors. Nineteen spinal operations (79%) were planned preoperative embolization(More)
A 68-year-old male presented with a traumatic subdural hematoma originating from a convexity meningioma the day after a motorcycle accident. Computed tomography disclosed a right temporal subdural and/or epidural mass. Emergent craniotomy revealed a convexity meningioma with thin subdural hematoma. The underlying brain was apparently healthy. The(More)
A 53-year-old man presented with malignant lymphoma manifesting as disturbances of walking and standing. Magnetic resonance (MR) imaging showed multifocal bifrontal lesions which were enhanced by gadolinium-diethylenetriaminepenta-acetic acid. Positron emission tomography (PET) with [18F]fluorodeoxyglucose showed high uptake of tracer in the lesion. The(More)
