An 11-year-old Japanese girl was diagnosed as having type 3 GM1 gangliosidosis by clinical symptoms and enzyme assay. She was the youngest among the patients with type 3 GM1 gangliosidosis whose clinical and neuroradiological findings have been documented. Clumsiness since early infancy and dystonia since early childhood which progressed slowly without(More)
OBJECTIVE Transcranial Doppler (TCD) findings for evaluation of the severity of vasospasm (VSP) in patients with ruptured aneurysmal subarachnoid hemorrhage are controversial. To clarify these TCD findings, intra-arterial digital subtraction angiography was used to simultaneously investigate the angiographic features of cerebral vessels and the cerebral(More)
A case of subarachnoid hemorrhage from ruptured aneurysm of the basilar bifurcation associated with occlusions of both internal carotid arteries at the neck is presented. Each internal carotid artery mainly received collateral flow at the cavernous portion from the internal maxillary artery through anastomotic artery of the foramen rotundum. Posterior(More)
PURPOSE We studied cerebral circulation in patients with occlusion of the main cerebral artery and investigated the efficacy of STA-MCA anastomosis. PATIENTS AND METHODS Thirty-six patients with occlusion of the main cerebral artery were studied. Twenty-three patients had occlusion of the internal carotid artery and 13 had occlusion of the middle cerebral(More)
The ostium of the recipient artery and the orifice of the donor artery must be clearly visualized for the establishment of microvascular anastomosis. Specially designed colored flexible cylindrical or T-shaped silicone rubber stents were made in various sizes (400 or 500 microns diameter and 5 mm length) and applied to bypass surgery in patients with(More)
Twelve patients associated with stenosis of the extracranial carotid artery underwent intraluminal balloon dilatation during carotid endarterectomy (CEA). There were 11 men and 1 woman, and age ranged from 56 to 73 years old. The rate of stenosis, shown by angiography, in each patient was from 60 to 85% in width. After securing carotid blood flow by a(More)
The authors report a case of metastatic brain tumor of tracheal cancer origin, itself a rare condition. A 55-year-old man was admitted with complaints of headache, atonic seizure of left lower limb and right temporal swelling. On admission, the patient had left recurrent nerve palsy. CT scan displayed right temporal bone destruction and ring-enhanced mass.(More)
There have been few guidelines in the field of nutritional management with regard to neurosurgical patients. In this review, caloric intake and nutritional parameters were measured in 24 patients in the acute stage and 32 patients in the chronic stage (prolonged unconscious state). We ascertained (1) whether the caloric intake was adequate or not, (2) the(More)
Two cases of subarachnoid hemorrhage caused by rupture of a basilar bifurcation aneurysm associated with occlusion of the internal carotid artery (ICA) at the neck are presented. Case 1, a 71-year-old female, was hospitalized in a coma. Angiography demonstrated occlusion of the bilateral ICA, collateral blood supply through the branches of the foramen(More)
