OBJECT Brainstem gliomas are common in children and have the worst prognosis of any brain tumor in this age group. On the other hand, brainstem gliomas are rare in adults, and the authors of some clinical studies have suggested that this lesion behaves differently in adults than in children. In the present study, the authors test an orthotopic C6 brainstem(More)
Fusiform dilation of the internal carotid artery (FDICA) is an infrequent vascular complication following resection of suprasellar lesions in the pediatric population, and its course appears to be benign without apparent clinical symptoms. However, data correlating symptomatic FDICA with bypass surgery are scarce. The authors here report 2 symptomatic cases(More)
The primary intracranial endodermal sinus tumor (EST) is regarded as a rare histological subtype that is often associated with components of other germ cell tumors, and there are no reports on the onset of intracranial ESTs after growth hormone (GH) replacement therapy. The authors report an extremely rare case of pure primary EST associated with GH(More)
BACKGROUND Ischemic cerebrovascular diseases are traditionally treated using an extracranial-intracranial (EC-IC) bypass. The use of the internal maxillary artery (IMA) in the subcranial-intracranial (SC-IC) bypass was recently described as an alternative treatment. However, the haemodynamics of this new approach have not been defined. METHODS The(More)
OBJECTIVE A retrospective review of the surgical outcome for patients with craniopharyngioma (CP) treated in a single neurosurgical center with surgical resection using visualization to ensure hypothalamic preservation. METHODS The study included 1054 patients. Before 2003, a pterional cranial approach was preferred for 78% of patients; after 2004, the(More)
OBJECTIVE To evaluate the usefulness of virtual reality (VR) technique for individualized preoperative planning of sphenoidal ridge meningioma. METHODS Multiple imaging data of CTA/MR were acquired from 41 surgical patients with sphenoidal ridge meningioma during the period from July 2009 to June 2013 were transferred into the Dextroscope system. A suite(More)
OBJECTIVE To retrospectively review 179 cases surgical treatments of craniopharyngiomas over a 7-year period, surgical experience as following. METHODS Dependent on the locations of the tumors to the floor of the third ventricle, they were classified into the superior type of the third ventricle floor in which tumors grew on the superior part of the third(More)
OBJECTIVE To evaluate the effectiveness of internal maxillary artery (IMA) - radial artery graft (RAG) - middle cerebral artery (MCA) bypass surgery for chronic arterial-sclerotic severe stenosis or occlusion of the internal carotid artery (ICA) or MCA. METHODS A retrospective study was conducted in 31 patients with ischemic cerebrovascular disease who(More)
BACKGROUND Giant intracranial aneurysms (GIAs) can be approached via microsurgical and endovascular techniques. Utilization of flow diversion devices (FDDs) has yielded favorable outcomes, and indications for cerebral revascularization have dramatically decreased. OBJECTIVE To evaluate the safety and validity of using internal maxillary artery (IMA)(More)
