BACKGROUND The purpose of this study was to present the clinical results of our retrospective series of carpal tunnel release (CTR) operations. For these operations we used a unique type of incision, for the first time, for treatment of carpal tunnel syndrome (CTS) consisting of a 1-cm semi-vertical (SV) incision made into the wrist crease for macroscopic open CTR. MATERIAL AND METHODS This retrospective study included 114 patients (101 females and 13 males) with CTR who were operated upon in our neurosurgery clinic between December 2010 and June 2015...

BACKGROUND: Cranioplasty, the repair of a skull vault defect by insertion of an object (bone or nonbiological materials such as metal or plastic plates), is a well-known procedure in modern neurosurgery. Brain protection and cosmetic aspects are the major indications of cranioplasty. A retroprospective study was conducted for evaluating the indications, materials used, complications, and outcome of cranioplasty. METHODS: This study was prospective from August 2013 to September 2015 and retrospective from August 2010 to July 2013...

INTRODUCTION: Prematurely fused metopic suture results in developmental anomaly named trigonocephaly. The treatment of trigonocephaly is a surgical reconstruction, starting from the simple suturectomy toward the complicated cranial vault reconstructions with aim to obtain enough endocranial space for normal development of the brain and aesthetic correction as well. THE AIM: The aim of our paper is to present our experience on this pathology in the Republic of Macedonia, stressing the trigonocephaly as one of the rare forms of craniosynostosis...

BACKGROUND: Ventriculoperitoneal (VP) shunt placement is one of the most commonly performed procedures in neurosurgery. One rare complication is the formation of an abdominal pseudocyst, which can cause shunt malfunction. CASE DESCRIPTIONS: We present four unique cases of abdominal pseudocyst formation. Our first patient initially presented with a right upper quadrant pseudocyst. Shunt was externalized and the distal end was revised with placement of catheter on the opposite side...

A software framework is described which was designed to process EEG, video of one eye, and head movement in real time, towards achieving early detection of microsleeps for prevention of fatal accidents, particularly in transport sectors. The framework is based around a pipeline structure with user-replaceable signal processing modules. This structure can encapsulate a wide variety of feature extraction and classification techniques and can be applied to detecting a variety of aspects of cognitive state. Users of the framework can implement signal processing plugins in C++ or Python...

The purpose of this study is to show the methodology for the examination of the white matter connections of the supplementary motor area (SMA) complex (pre-SMA and SMA proper) using a combination of fiber dissection techniques on cadaveric specimens and magnetic resonance (MR) tractography. The protocol will also describe the procedure for a white matter dissection of a human brain, diffusion tensor tractography imaging, and three-dimensional documentation. The fiber dissections on human brains and the 3D documentation were performed at the University of Minnesota, Microsurgery and Neuroanatomy Laboratory, Department of Neurosurgery...

BACKGROUND: In this manuscript the authors describe the application of a new exoscope which offers three-dimensional (3D) visualization in cranial and spinal neurosurgery in detail. METHODS: Five cranial and eleven spinal procedures were performed using a 3D-exoscope. Instrument handling, repositioning of the exoscope, handling of the image control unit, the adjustment of magnification and focal length, the depth perception, the image quality, the illumination, and the comfort level of the posture during the procedure were assessed via a questionnaire...

The field of pituitary surgery was born in the first decade of the twentieth century in Europe, and it evolved rapidly with the development of numerous innovative surgical techniques by some of the founding fathers of neurosurgery. This study investigates the pioneering Italian treatise on pituitary surgery, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), published in 1911 by Giovanni Verga (1879-1923), a surgeon from Pavía and one of Golgi's disciples. This little-known monograph compiles the earliest experience on pituitary surgery through the analysis of the first 50 procedures performed between 1903 and 1911...

Placement of a ventricular catheter is the most common and easiest procedure in neurosurgery. Usually, the procedure is performed using anatomical landmarks. However, despite the apparent ease of this manipulation, its results are not always satisfactory. According to the literature data, the rate of improperly placed ventricular catheters amounts to 10-40%, which is directly correlated with the risk of shunt dysfunction. The use of special equipment, such as ultrasound scanners, endoscopes, stereotactic devices, and neuronavigation systems, significantly increases success of surgery...

BACKGROUND: Poor outcomes of surgical treatment for complex cerebral aneurysms due to the development of cerebral ischemia were the cause to use cerebral revascularization surgery for this pathology. OBJECTIVE: the study objective was to master a high-flow extracranial-intracranial (EC-IC) artery bypass technique and evaluate its application in surgical treatment of complex and giant cerebral aneurysms as well as complex lesions of the brachiocephalic arteries. MATERIAL AND METHODS: Fifty two patients underwent high-flow IC-EC bypass surgery; of these, 34 patients had complex cerebral aneurysms, and 18 patients had complex stenotic occlusive lesions of the brachiocephalic arteries...

In the early days of modern neurological surgery, the inconveniences and potential dangers of general anesthesia by chloroform and ether using the so-called "open-drop technique" led to the quest for alternative methods of anesthesia. This became all the more necessary, since patient positioning and the surgical arrangements often hindered the use of a drop bottle. One approach to solve this problem was intra-rectal ether application. The present article aims to shed light on this original, less well-known anesthesia technique in the neurosurgical field...

BACKGROUND: Brain abscess is a focal infection of the brain, that begins as a localized area of cerebritis. In immunocompetent patients, bacteria are responsible for >95% of brain abscess, and enter the brain either through contiguous spread following otitis, sinusitis, neurosurgery, or cranial trauma, or through hematogenous dissemination. AIMS: To identify recent advents in the field. Sources We searched Medline and Embase for articles published during years 2012-2016, with the keywords 'brain', and 'abscess'...

INTRODUCTION: The recent introduction of incision-less lesional neurosurgery using Gamma Knife and MRI-guided focused ultrasound has revived interest in lesional treatment options for tremor disorders. Preliminary literature researches reveal that the consistency of treatment effects after lesional neurosurgery for tremor has not formally been assessed yet. Similarly, the efficacy of different targets for lesional treatment and incidence of persistent side effects of lesional neurosurgical interventions has not been comprehensively assessed...

Robot-assisted stereotactic neurosurgery is an emerging technology with a growing range of applications. The ROSA system is a robotic stereotactic system that has been shown to be accurate in laboratory studies and large case series. The goal of this study was to examine the accuracy of the ROSA across different registration methods as well as different clinical applications. Sixteen patients with one hundred and seventeen stereotactic trajectories were examined. Accuracy was compared by measuring the distance between the trajectory target and the actual termination of the device as determined by imaging...

During the last 10 years, microscope-integrated indocyanine green fluorescence (m-ICG) has been widely used for assessing real-time blood flow during aneurysm surgery. More recently, an endoscope-integrated indocyanine green fluorescence (e-ICG) has been adopted as a versatile tool during different endoscopic neurosurgical procedures. The purpose of the present report is to evaluate multimodal applications of e-ICG during different endonasal, intraventricular, aneurysm and brain tumor surgeries and provide technical nuances...
