BACKGROUND: Re-irradiation (Re-RT) is offered widely in clinical routine, and has been established as a key element in the treatment of recurrent gliomas. At our center, generally re-resection is performed widely by an experienced neurosurgical team. Thus, Re-RT mostly offered to patients with macroscopic residuals or irresectable lesions, is applied later compared to other centers. Therefore, we sought to validate the Combs Prognostic Score developed in 2012 using our independent patient cohort...

Background Ameloblastomas are a rare tumor entity accounting for only 10% of all odontogenic tumors. They mostly originate from the mandible. Only a few cases are known to grow aggressively and to invade the orbit, nasal cavity, or even the brain. Patient and Methods/Case Report We present the case of a 57-year-old patient who was admitted with a huge tumor involving the nasal cavity, the left maxilla, and the anterior fossa. Histologic diagnosis was made by biopsy. A combined two-stage neurosurgical maxillofacial approach was planned...

After a four-year planning period, a joint Ethiopian/Norwegian training program in neurosurgery was started in June 2006. The collaborating partners were the Addis Ababa University, Department of surgery, Tikur Anbessa specialized hospital, the University of Bergen, Haukeland University hospital and Myungsung Christian Medical Center, a Korean missionary hospital in Addis Ababa. A Memorandum of understanding was signed at Dean/CEO levels. Although other initiatives have been involved in supporting neurosurgery in Addis Ababa during the same period, this institutionally founded program has been the main external contributor to neurosurgical capacity building through the education of 21 Ethiopian neurosurgeons, and in supporting a sustainable environment for neurosurgical training within a network of five centres in Addis Ababa...

We propose a method for the automated identification of key white matter fiber tracts for neurosurgical planning, and we apply the method in a retrospective study of 18 consecutive neurosurgical patients with brain tumors. Our method is designed to be relatively robust to challenges in neurosurgical tractography, which include peritumoral edema, displacement, and mass effect caused by mass lesions. The proposed method has two parts. First, we learn a data-driven white matter parcellation or fiber cluster atlas using groupwise registration and spectral clustering of multi-fiber tractography from healthy controls...

Simulation of the actual procedure is a simple and yet effective method of increasing patient safety and reducing the rate of unexpected adverse effects. We present our experience with 2 cases of preprocedural simulation on healthy volunteers that were performed in the intraoperative magnetic resonance imaging suite. During one of the cases, we also simulated a scenario of sudden cardiac arrest. Such an approach helped us to refine the procedures and coordinate the work of different teams within the intraoperative magnetic resonance imaging suite as well as improve the quality of patient management...

BACKGROUND: Nonmissile penetrating head injuries (NPHIs) in the civilian population are rare but potentially fatal. Although numerous cases have been reported in the literature, the surgical management of such injuries is still ambiguous, especially with development of surgical techniques. Here, we report 5 cases of NPHIs managed with different surgical techniques and review the literature on surgical treatment of these injuries to outline the appropriate management for these patients from a neurosurgical perspective...

Quantitative susceptibility mapping (QSM) is an MR technique that depicts and quantifies magnetic susceptibility sources. Mapping iron, the dominant susceptibility source in the brain, has many important clinical applications. Herein, we review QSM applications in the diagnosis, medical management, and surgical treatment of disease. To assist in early disease diagnosis, QSM can identify elevated iron levels in the motor cortex of amyotrophic lateral sclerosis patients, in the substantia nigra of Parkinson's disease (PD) patients, in the globus pallidus, putamen, and caudate of Huntington's disease patients, and in the basal ganglia of Wilson's disease patients...

OBJECTIVE Craniopharyngiomas remain a particularly formidable challenge in the neurosurgical field. Because these lesions involve the hypothalamus and ophthalmological systems, their resection is associated with either higher rates of mortality and recurrence or a lower rate of radical resection. The authors report the outcomes of aggressive surgeries based on an anatomical subclassification of craniopharyngiomas. METHODS Clinical and ophthalmological examinations, imaging studies, endocrinological studies, neuropsychological function, and surgical complications in all patients who had undergone microsurgical resection for craniopharyngioma at Osaka City University hospital between January 2000 and December 2014 were retrospectively reviewed through the medical records...

: Laser-induced thermal therapy has become a powerful tool in the neurosurgical armamentarium. The physics of laser therapy are complex, but a sound understanding of this topic is clinically relevant, as many centers have incorporated it into their treatment algorithm, and educated patients are demanding consideration of its use for their disease. Laser ablation has been used for a wide array of intracranial lesions. Laser catheter placement is guided by stereotactic planning; however, as the procedure has popularized, the number of ways in which the catheter can be inserted has also increased...

BACKGROUND: Arterial blood gas (ABG) overutilization leads to increased costs, inefficient use of staff work-hours, patient discomfort and blood loss. We developed guidelines to optimize ABG utilization in the intensive care unit (ICU). METHODS: ABG utilization guidelines were implemented on all adult ICUs in our institution: three medical, two trauma-surgery, one cardiovascular and one neurosurgical ICU. While relying on pulse oximetry, we encouraged the utilization of ABGs after an acute respiratory event or for a rational clinical concern, and discouraged obtaining ABGs for routine surveillance, after planned changes of PEEP or FiO2 on the mechanical ventilator, for spontaneous breathing trials, or when a disorder was not suspected...

INTRODUCTION: Large (1.5-2.5 cm) and giant (>2.5 cm in diameter) aneurysms of the internal carotid artery (ICA) remain one of the complex neurosurgical pathologies in terms of microsurgery. In recent years, endovascular techniques for treatment of paraclinoid aneurysms, in particular ICA reconstruction using flow-diverting stents, have become a priority. However, surgery of flow stents has a number of limitations, therefore the choice of treatment in each case is individual. PURPOSE: To analyze the results of direct surgery in patients with large and giant aneurysms of the ICA and to determine the role and place of modern microsurgical techniques in the treatment of this vascular disease...

OBJECTIVE The use of high-field intraoperative MRI has been largely studied for the treatment of intracranial tumors in adult patients. In this study, the authors investigated the safety, advantages, and limitations of high-field iMRI for cranial neurosurgical procedures in pediatric patients, with particular attention to craniopharyngiomas and gliomas. METHODS The authors performed 82 surgical procedures in patients under 16 years of age (range 0.8-15 years) over an 8-year period (2007-2014) using iMRI. The population was divided into 3 groups based on the condition treated: sellar region tumors (Group 1), gliomas (Group 2), and other pathological entities (Group 3)...

Streamline tractography algorithms infer connectivity from diffusion MRI (dMRI) by following diffusion directions which are similarly aligned between neighboring voxels. However, not all white matter (WM) fascicles are organized in this manner. For example, Meyer's loop is a highly curved portion of the optic radiation (OR) that exhibits a narrow turn, kissing and crossing pathways, and changes in fascicle dispersion. From a neurosurgical perspective, damage to Meyer's loop carries a potential risk of inducing vision deficits to the patient, especially during temporal lobe resection surgery...

OBJECTIVE Endoscopic removal of intracerebral hematomas is becoming increasingly common, but there is no standard technique. The authors explored the use of a simple image-guided endoscopic method for removal of spontaneous supratentorial hematomas. METHODS Virtual reality technology based on a hospital picture archiving and communications systems (PACS) was used in 3D hematoma visualization and surgical planning. Augmented reality based on an Android smartphone app, Sina neurosurgical assist, allowed a projection of the hematoma to be seen on the patient's scalp to facilitate selection of the best trajectory to the center of the hematoma...
