ABSTRACT Objective Correlate the middle cerebral artery bifurcation aneurysm morphology with the pre-operative and intra-operative risk of rupture. Methods Forty patients with 46 middle cerebral artery bifurcation aneurysms were treated microsurgically by the same surgeon. Aneurysms were classified according to shape and the Fisher test was applied to analyze the effect of morphology on the pre-operative and in...
OBJECTIVE: The authors show their experience with brainstem cavernomas, comparing their data with the ones of a literature review. METHODS: From 1998 to 2009, 13 patients harboring brainstem cavernomas underwent surgical resection. All plain films, medical records and images were reviewed in order to sample the most important data regarding epidemiology, clinical picture, radiological findings and surgical outc...
CONTEXTO: O conhecimento das estruturas anatômicas da artéria carótida externa por meio do estudo estereoscópico pode determinar melhores resultados em microcirurgias da artéria carótida externa. OBJETIVO: Descrever as estruturas da artéria carótida externa sob a visão estereoscópica, identificando seus múltiplos aspectos. MÉTODOS: Doze regiões cervicais foram dissecadas, utilizando-se microscópico cirúrgico co...
CONTEXTO: O espaço infratentorial do crânio é uma região que possui complexa rede de artérias que vascularizam o tecido cerebelar e o tronco encefálico. Sua complexa anatomia tridimensional deve ser profundamente entendida pelo neurocirurgião vascular e pelo radiologista intervencionista. OBJETIVO: Descrever as principais artérias do espaço infratentorial e seu trajeto, bem como sua relação com a topografia das...
BACKGROUND: Postoperative cerebrospinal fluid (CSF) fistula is the most serious complication after transsphenoidal surgery. OBJECTIVE: To analyze the incidence of CSF fistula after endoscopic transsphenoidal surgery for tumor removal in sellar region; to discuss associated factors and methods used for sellar closure. METHOD: Retrospective study of 67 patients (73 surgeries) operated via transsphenoidal endoscop...
OBJECTIVE: Ependymomas are rare intracranial neuroepithelial tumors and the most common location is intramedullary. The aim was to analyze the characteristics of these tumors to determine the patients' overall survival and the likelihood of recurrence. METHOD: Data of clinical presentation, tumor location, duration of symptoms, degree of resection and complementary treatment of 34 patients with intracranial epe...
OBJECTIVE: The main objective when resecting benign brain lesions is to minimize risk of postoperative neurological deficits. We have assessed the safety and effectiveness of craniotomy under local anesthesia and monitored conscious sedation for the resection of lesions involving eloquent language cortex. METHODS: A retrospective review was performed on a consecutive series of 12 patients who underwent cranioto...
The goal of this study was to accomplish the cross-cultural adaptation of a quality of life instrument, specific for neurosurgical patients, called Innsbruck Health Dimensions Questionnaire for Neurosurgical Patients (IHD-NS). Thirty patients participated in this study, male and female, all having been submitted to brain tumor surgery more than twelve months before, and whose ages ranged from 26 to 66. After th...
OBJECTIVE: To present the magnetic resonance (MR) imaging findings of 78 patients with meningiomas diagnosed in a single institution. METHOD: 78 patients with histological proven intracranial meningioma were studied. There were 52 female and 26 male patients (median=56 years). All MR imaging examinations were performed with 1.5-T MR imaging unit with standard protocol. The images were studied by two neuroradiol...
