M2 segment thrombectomy is not associated with increased complication risk compared to M1 segment: A meta-analysis of recent literature.

Introduction: Recent clinical comparisons of M1 and M2 segment endovascular thrombectomy have reached incongruous results in rates of complication and functional outcomes. This study aims to clarify the controversy surrounding this rapidly advancing technique through literature review and meta-analysis.

Methods: A Pubmed search was performed (January 2015-September 2019) using the following keywords: "M2 AND ("stroke" OR "occlusion") AND ("thrombectomy" OR "endovascular")".

Usefulness and Impact of Intraoperative Imaging for Glioma Resection on Patient Outcome and Extent of Resection: A Systematic Review and Meta-Analysis.

Background: Diffusion tensor imaging (DTI), functional magnetic resonance imaging (fMRI), and intraoperative magnetic resonance imaging (iMRI) permit greater visualization and more accurate presurgical planning. Meta-analysis of these techniques for maximizing resection, postoperative functionality, and survival may further validate purported strengths of these techniques compared with standard neuronavigation.

Methods: A systematic search of the PubMed database was conducted in line with the PRISMA guidelines for meta-analysis with the following keywords: "Diffusion tensor imaging" OR "intraoperative MRI" OR "functional MRI" AND "glioma surgery resection outcome.

Patients with Parkinson Disease Experience Increased Perioperative Complications Following Cervical Decompression and Fusion: A Retrospective Review of the National Inpatient Sample.

Background: Despite improved medical management, the incidence of spinal pathology remains high in patients with Parkinson disease (PD). Several studies have investigated lumbar spine surgery in this population, but data regarding costs and perioperative complications for patients undergoing cervical decompression/fusion on a nationwide scale are lacking.

Methods: Cases of cervical spinal decompression, fusion, or exploration in years 2008-2014 were collected via the Healthcare Cost and Utilization Project National Inpatient Sample.
