disadvantages include the lack of an electrophysiological guide, delayed effectiveness such that clinical improvement can take months, and late complications that may arise and are irreversible. 72 , 83 Consequently, certain specialists reserve SRS for patients who are not candidates for surgery. The purpose of this systematic review was to identify and summarize the literature to provide consensus guidelines for practice as endorsed by the International Stereotactic Radiosurgery Society. Methods Article Selection This systematic review was conducted according to PRISMA

number of case series and imaging studies evaluating the significance of regional ischemia have emerged. A systematic review of the literature pertaining to CPA and the role of cerebral revascularization may highlight a treatment paradigm for this difficult-to-treat condition. Fig. 1. Representative angiograms demonstrating CPA that occupies the right temporal and occipital lobes. A: Right internal carotid artery (ICA) angiogram obtained during the arterial phase with anteroposterior projection demonstrating no early venous phase, normal caliber of proximal vessels

our knowledge, this is the first systematic review of cost-effectiveness studies of cranial neurosurgery procedures. Methods Search Strategy and Study Selection This study was registered at the International Prospective Register of Systematic Reviews (PROSPERO; CRD42017064708). We performed a systematic review of literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, using 3 databases—PubMed, EMBASE, and the Cochrane Library—to identify all economic evaluation studies of cranial neurosurgery. 48 We used the

occur with progression in the epidural space. 2 , 22 Thus, the purpose of this study was to systematically review the literature for outcomes in patients with spinal metastases treated with SBRT in the “de novo” setting, that is, patients who have not had previous surgery or irradiation to the affected spinal segment. Methods A systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards of quality for reporting systematic reviews with the assistance of a designated medical librarian team. 14 Search

a readmitted and the overall group. Excluded studies comprised those that reported readmission as re-operation, complications, mortality, morbidity, or as part of a composite outcome. Based on the inclusion and exclusion criteria, 25 articles were retained for full-text examination, of which 12 were chosen to be included in this review. Figure 2 is a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flow diagram, which illustrates the number of articles at each data acquisition level, the number of excluded articles, and the reasons for

incidentally found asymptomatic SDAVFs. 41 We present 5 cases of asymptomatic SDAVFs and report the results of our systematic review to investigate the differences between symptomatic and asymptomatic SDAVFs in terms of clinical features, imaging findings, and therapies. Methods The protocol of this study was approved by the ethics committees of Hiroshima University and Kagoshima University. Because this was a retrospective noninvasive study, written informed consent was not obtained from patients. The methods and guidelines of this systematic review followed PRISMA

to assess the totality of trial evidence on this topic, especially as we could not identify any existing systematic reviews. To best understand how the efficacy and safety of osteoinductive bone graft substitutes compare with those of autografts and allografts in lumbar fusion, we performed a systematic review and metaanalysis of all published controlled trials comparing the 2 strategies. Methods Study Selection We searched MEDLINE (1950 to April 2009), EMBASE (1980 to April 2009), and the Cochrane Central Register of Controlled Trials (1950 to April 2009

complications are transient, some result in permanent deficit and severe disability in patients undergoing lumbar spine surgery. 7 , 11 , 15 , 21 , 23 , 28 , 32 Thus, surgeons must be mindful of intraoperative patient positioning to relieve potentially harmful pressure upon susceptible structures. 4 Complications related to positioning during lumbar spine surgery are typically analyzed from an institutional perspective. 14 , 26 , 29 , 46 A systematic review of complications following the numerous positioning options for lumbar spine surgery has not been previously

the evolution of neuroimaging came refinement in the technique and the target. Several large Gamma Knife surgery (GKS) series have already advocated for the safety and efficacy of RS, in particular, by reporting long-term and very-long-term results. 63 , 110 , 114 , 115 , 144 Additionally, a small number of studies have reported outcomes for the other RS techniques, including the LINAC and CKR, though with a more limited number of patients and follow-up periods. 1 , 12 , 31 , 102 , 119 , 124 , 125 , 129 , 138 The aims of this systematic review are to provide an

verify the claims that MIS techniques for lumbar microdiscectomy are better than conventional methods. 34 Complications related to lumbar microdiscectomy are typically analyzed from an institutional or individual surgeon perspective. 4 , 5 , 31 A systematic review and meta-analysis of complications following the various surgical techniques to perform lumbar microdiscectomy has not been previously performed. Accurate knowledge of complication rates following conventional open, MED, and percutaneous approaches can be used to help educate patients and surgeons during
