Review
The anterior cerebral artery (ACA) varies considerably and this complicates the description of the normal anatomy. The segmentation of the ACA is mostly agreed on by different authors, although the relationship of the pericallosal and callosomarginal arteries (CmA) is not agreed upon. The two basi...
Original Investigation
AIM: Reconstruction technique advances have created renewed enthusiasm for the expanded endonasal approach (EEA). However, as with any new technique, early experiences inevitably lead to more selective use of these techniques. We reviewed our experience of the expanded endonasal endoscopic approac...
AIM: Total surgical resection of pituitary macroadenomas is difficult due to the location of the adenoma and the propensity to invade surrounding tissues. The purpose of this study was to evaluate the risk factors for invasive and aggressive pituitary macroadenomas using radiological, hormonal, cl...
AIM: To analyse the effect of MMP-3 (Matrix Metalloproteinase Enzyme-3)-one of the extracellular matrix proteins- on the prognosis and biological behaviour of meningiomas. MATERIAL and METHODS: 79 cases of meningioma that were operated in our clinic between 2005 and 2010 were retrospectively anal...
AIM: Hypervascular intracranial tumors may cause serious bleeding in surgery. Though pre-operative endovascular embolization of tumor is a widely accepted method, sometimes despite embolization, an effective and safer intraoperative hemostatic technique is needed to prevent or at least decrease th...
AIM: Tumors of various organs that metastasize to bone do not neglect calvarium as a target. The aim of this study was to characterize the calvarial tumors. MATERIAL and METHODS: We retrospectively reviewed 45 consecutive patients operated for calvarial masses from January 2002 till May 2012 at o...
AIM: To share the results of conventional surgery in rhinorrhea and the contribution of computerized tomography (CT) cisternography to determination of the site of cerebrospinal fluid (CSF) leak. MATERIAL and METHODS: Twelve cases treated for spontaneous rhinorrhea were included in this study. All...
AIM: Decompressive hemicraniectomy for a malignant middle cerebral artery infarct can be a life-saving surgical treatment. We aimed to investigate the surgical treatment results in cases that underwent decompressive hemicraniectomy for a malignant middle cerebral artery infarct in this study. MAT...
AIM: Giant arteriovenous malformations (i.e., those greater than 6 cm maximum diameter or volume > 33 cc) are difficult to treat and often carry higher treatment morbidity and mortality rates. In our study, we reviewed the angiographic results and clinical outcomes for 11 patients with giant arter...
AIM: To compare the beneficial effects of cisternal blood clot evacuation with or without microsurgical fenestration of the lamina terminalis (LT) on symptomatic vasospasm during the course of aneurysmal subarachnoid hemorrhage. MATERIAL and METHODS: This was a clinical, retrospective study that i...
AIM: Glasgow Coma Scale (GCS) is the most applied tool for classifying intensity of coma and predicting patient outcomes with traumatic brain injuries. The present study was conducted with the aim of comparing two criteria of Full Outline of UnResponsiveness (FOUR) scale and GCS in predicting prog...
AIM: Traumatic subdural effusion (TSE) occurs following traumatic brain injury and may be treated by either conservative methods or surgical procedure commonly according to the patients’ clinical information. We aimed to compare the effective rate of effusion removal and the standardized mor...
AIM: Traumatic brain injury is one of the leading causes of mortality and morbidity worldwide. The role of prophylactic anti-epileptic drugs has been established. Phenytoin used traditionally for this purpose carries a burden of adverse reactions and cumbersome need of monitoring and maintaining l...
AIM: Tyrosine kinase receptor-B (TrkB), a high-affinity receptor for brain-derived neurotrophic factor (BDNF), functions via specific binding with the BDNF. Although studies have shown that BDNF promotes the expression of glutamate transporter-1 (GLT-1) in the glial cells during neurodegeneration,...
AIM: To investigate the indications and clinical value of the surgical therapy of neurocysticercosis (NCC). MATERIAL and METHODS: We retrospectively reviewed all 10 patients with NCC treated surgically from January 2009 to January 2014 in our institute. The NCC types included parenchymal cysticerc...
AIM: Dynamic plates have been popularized to promote cervical spine fusion. There are no studies comparing the effectiveness and complications between traditional static plates and new dynamic plates (Vectra-T, Synthes, Switzerland). MATERIAL and METHODS: From June 2009 to October 2012, 70 patient...
AIM: To investigate whether C1-occipital condyle complex (CC complex) screws can be safely and rapidly placed without guidance in basilar invagination patients with atlas assimilation. MATERIAL and METHODS: The occipital-cervical (OC) junction was fixed posteriorly in 8 basilar invagination patien...
AIM: To assess the feasibility and efficacy of TLIF with unilateral pedicle screw and contralateral percutaneous lumbar transfacet screw fixation for the treatment of lumbar degenerative disorders. MATERIAL and METHODS: A series of computed tomography (CT) digital images from 60 patients (30 males...
AIM: Misplacement of pedicle screw is the serious complication of spinal surgeries. Intraoperative imaging techniques and navigation systems are currently in use for the prevention of this complication. The aim of this study was to document the results of our experience with the navigation and int...
AIM: Two different ventilation protocols during general anesthesia have been compared regarding their effects on amount of epidural bleeding during lumbar microdiscectomy in the prone position. Previous studies have not not revealed a relationship between ventilation mode and epidural bleeding in ...
AIM: To evaluate the effects of NMDA receptor antagonist memantine and pancaspase inhibitor Q-VD-Oph in combination or alone in experimental spinal cord injury. MATERIAL and METHODS: 45 male Sprague-Dawley rats were divided into five groups. Spinal cord injury was created with the clip compressio...
Case Report
Astroblastoma is a rare and distinct type of aggressive glial tumor for which there is much confusion regarding the diagnostic criteria. We present a case of astroblastoma and review all relevant literature, aiming to discuss astroblastoma from the clinical, pathological, management, and prognosti...
The aim of this report is to investigate the pathogenesis and surgical treatment of encephalocele located in the sphenoid sinus and presented with spontaneous rhinorrhea. The data of a patient with sphenoid sinus encephalocele was analyzed in association with the review of literature. The patient ...
Glioblastoma (GBM) is the most aggressive primary tumor of the central nervous system (CNS) in adults. Its growth has been always described as locally invasive. This tumor rarely penetrates dura mater and invades extracranial structures. We present a case of GBM, which occurred in a 39-year-old ma...
