Endovascular and surgical techniques are conventional options for treating intracranial aneurysms, but criteria for selecting an optimal approach for individual patients remain variable across practitioners and institutions. While endovascular and surgical approaches are generally used alone, both modalities combined in single patients can produce efficacious outcomes. The aim of this study was to evaluate outcomes of combined, concomitant endovascular and surgical modalities in the treatment of multiple and/or complex aneurysms in single patients...

A lumbar disc herniation resulting in surgery may be an incisive event in a patient's everyday life. The patient's recovery after sequestrectomy may be influenced by several factors. There is evidence that regular physical activity can lower pain perception and improve the outcome after surgery. For this purpose, we hypothesized that patients performing regular sports prior to lumbar disc surgery might have less pain perception and disability thereafter. Fifty-two participants with a single lumbar disc herniation confirmed on MRI treated by a lumbar sequestrectomy were included in the trial...

As a result of the demographic shift in western societies, the mean age at presentation of patients suffering from chronic subdural hematomas (cSDH) is increasing. Therapeutic strategies, surgical and non-surgical, need to be reevaluated and adapted accordingly. Age is considered to be a positive risk factor for a higher perioperative morbidity and mortality. The purpose of this study is to determine if old age (≥85 years) should be seen as a contraindication for surgical treatment. Two groups (56 patients each) with cSDH over and below 85 years of age from a single neurosurgical department with well-defined surgical treatment guidelines were retrospectively analyzed...

The surgical procedures used for arthrodesis in the lumbar spine for degenerative lumbar diseases remain controversial. This systematic review aims to assess and compare clinical outcomes along with the complications and fusion of each technique (minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) or minimally invasive lateral lumbar interbody fusion (MIS LLIF)) for treatment of degenerative lumbar diseases. Relevant studies were identified from Medline and Scopus from inception to July 19, 2016 that reported Oswestry Disability Index (ODI), back and leg pain visual analog score (VAS), postoperative complications, and fusion of either technique...

In clipping surgery for aneurysmal subarachnoid hemorrhage (aSAH), critical steps include clot removal and dissection of aneurysms without premature rupture or brain injuries. To pursue this goal, a piezo actuator-driven pulsed water jet (ADPJ) system was introduced in this study. This study included 42 patients, who suffered aSAH and underwent clipping surgery. Eleven patients underwent surgery with the assistance of the ADPJ system (ADPJ group). In the other 31 patients, surgery was performed without the ADPJ system (Control group)...

The indications of surgery for thalamic high-grade gliomas are not well established. The present study investigated the outcome of 21 patients treated by surgery and reports the high incidence of distant recurrences including disseminations after successful removal. Twenty-one patients with thalamic high-grade gliomas not invading the pyramidal tract or midbrain underwent cytoreductive surgery at our institute from June 1997 to August 2015. Surgery was performed with the aid of a neuronavigation system, electrophysiological monitoring, and fluorescence navigation...

It is difficult to treat large internal carotid aneurysms with simple surgical clipping. Here, we present a retrograde suction decompression (RSD) procedure for large internal carotid aneurysms using a balloon guide catheter combined with a blood-returning circuit and a superficial temporal artery to middle cerebral artery (STA-MCA) bypass.All patients underwent an STA-MCA bypass before the temporary occlusion of the internal carotid artery (ICA). A 6-French sheath was inserted into the common carotid artery (CCA), and a 6-French Patrive balloon catheter was placed into the ICA 5 cm past the bifurcation...

The objective of this study is to explore the cause of early abnormal muscle response (AMR) disappearance during microvascular decompression for hemifacial spasm and the clinical outcomes of these patients. Three hundred seventy-two patients received microvascular decompression (MVD) under intraoperative electrophysiological monitoring in Nanjing Drum Tower Hospital in 2014; the characteristic AMR of HFS was observed in 359 patients during the operation. And the 359 patients were divided into two groups based on whether AMR had remained before the beginning of the decompression procedure for offending vessels...

REVIEW
Soha Alomar, Mohamad Bakhaidar
The goal of this review is to discuss the various imaging modalities to study neuropathic pain and its future implication in understanding pain network, for the diagnosis and management of patients with chronic neuropathic pain. Neuropathic pain is characterized by pain secondary to lesions or dysfunction of the central nervous system (CNS) or the peripheral nervous system. Neuropathic pain is generally chronic and disabling, and responds poorly to conventional treatment. Although our understanding of the imaging changes in chronic pain state is evolving, we still face practical challenges in implementing these finding to objectively diagnose and follow treatment response in patients with chronic pain and to guide targeted and individualized treatment to each chronic pain condition...

The improvement of pain and functionality is the major goal of a surgical intervention. Thus, the purpose of the present prospective study was to evaluate whether subjective sensory deficits in patients with lumbar radiculopathy caused by a lumbar disc herniation are related to clinical status, using several outcome scores and the quantitative sensory testing (QST) pre- and 12 months postoperatively. We applied the QST in 52 patients with a single lumbar disc herniation treated by lumbar sequestrectomy pre- and 12 months postoperatively...

Hemodynamic parameters play a significant role in the development of cerebral aneurysms. Parameters such as wall shear stress (WSS) or velocity could change in time and may contribute to aneurysm growth and rupture. However, the hemodynamic changes at the rupture location remain unclear because it is difficult to obtain data prior to rupture. We analyzed a case of a ruptured middle cerebral artery (MCA) aneurysm for which we acquired imaging data at three time points, including at rupture. A patient with an observed MCA aneurysm was admitted to the emergency department with clinical symptoms of a subarachnoid hemorrhage...

Tumor consistency is a critical factor that influences operative strategy and patient counseling. Magnetic resonance imaging (MRI) describes the concentration of water within living tissues and as such, is hypothesized to predict aspects of their biomechanical behavior. In meningiomas, MRI signal intensity has been used to predict the consistency of the tumor and its histopathological subtype, though its predictive capacity is debated in the literature. We performed a systematic review of the PubMed database since 1990 concerning MRI appearance and tumor consistency to assess whether or not MRI can be used reliably to predict tumor firmness...

High-grade craniofacial osteosarcoma (CFOS) is an aggressive malignancy with a poor prognosis. Our goals were to evaluate treatment outcomes in those treated at a single referral institution over 35 years and to compare our results to the available literature. A retrospective analysis of all 42 patients treated between 1980 and 2015 at Oslo University Hospital, Norway, identified in a prospectively collected database, was conducted. Mean follow-up was 79.6 months. Overall survival at 2 and 5 years was 70...

As it grows in size, an intracranial aneurysm (IA) is prone to rupture. In this study, we compared two extreme groups of IAs, ruptured IAs (RIAs) smaller than 10 mm and un-ruptured IAs (UIAs) larger than 10 mm, to investigate the genes involved in the facilitation and prevention of IA rupture. The aneurismal walls of 6 smaller saccular RIAs (size smaller than 10 mm), 6 larger saccular UIAs (size larger than 10 mm) and 12 paired control arteries were obtained during surgery. The transcription profiles of these samples were studied by microarray analysis...

Endoscopy in cerebellopontine angle surgery is an increasingly used technique. Despite of its advantages, the shortcomings arising from the complex anatomy of the posterior fossa are still preventing its widespread use. To overcome these drawbacks, the goal of this study was to define the anatomy of different endoscopic approaches through the retrosigmoid craniotomy and their limitations by surgical windows. Anatomical dissections were performed on 25 fresh human cadavers to describe the main approach-routes...

P Dammann, C Schaller, U Sure
In this review, the authors perform a database search and summarize and discuss all eligible studies that provide (subgroup) analysis of the postoperative seizure outcome of patients with cavernoma-related epilepsy undergoing sole lesionectomy or lesionectomy including the hemosiderin rim. Based on the currently available data, the authors conclude that if surgical treatment of cavernoma-related epilepsy is performed, the peri-lesional hemosiderin should be resected. However, cases of eloquent or multiple localization or widespread hemosiderin deposit in which a complete resection is challenging should undergo a specific preoperative work-up...

The authors describe a case of a purely primary extramedullary spinal germinoma in a young Chinese male. Primary spinal germinoma is extremely rare tumor. Currently, less than 30 histologically verified spinal germinoma cases have been reported previously, mostly involving Asian of Japanese descent. This 24-year-old male suffered from progressive low back pain radiating to both legs. Magnetic resonance imaging showed a well-demarcated, intradural extramedullary mass at the level of L2 and L3. The lesion was totally removed and was confirmed as a germinoma...
