Introduction: Primary CNS leiomyosarcomas are rare, dural-based intracranial or intravertebral tumors seen in immunocompromised patients and are associated with latent EBV infection. They may mimic a meningioma or schwannoma on imaging but their clinical presentation progresses much more rapidly. Often times, these tumors are hard to distinguish from secondary, metastatic leiomyosarcoma.

Article Synopsis
  • Dural arteriovenous fistulas (DAVF) at the craniocervical junction are rare, showing different venous drainage patterns, with patients presenting symptoms like hemorrhage or myelopathy.
  • A study reviewed 50 case reports involving 115 patients, revealing that inferior drainage is linked to myelopathy, while superior drainage often leads to hemorrhage.
  • Proper classification of venous drainage is crucial for treatment decisions, with transvenous embolization being optimal for superior drainage and surgical clipping being an alternative if endovascular methods are unsuitable.

Background: Several predictors have been studied for shunt dependency after stroke and other brain injuries. However, little is known about the association between ventriculostomy-associated infections (VAIs) and impaired cerebrospinal fluid (CSF) outflow. Moreover, gram-negative (GN) VAIs induce a potent neuroinflammatory process and are clinically challenging to treat.

Objective We aim to demonstrate the safety and effectiveness of extra-femoral endovascular access for mechanical thrombectomy for acute ischemic stroke patients whose vascular anatomy precludes safe or maneuverable trans-femoral access. Methods Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to conduct a systematic review and meta-analysis with articles published until March 2018. The search protocol, including research questions and inclusion and exclusion criteria, were developed a priori.

Background: Realistic virtual reality (VR) simulators have greatly expanded the tools available for training surgeons and interventionalists. While this technology is effective in improving performance in many fields, it has never been evaluated for neuroendovascular procedures. This study aims to determine whether VR is an effective tool for improving neuroendovascular skill among trainees.

Glioblastoma multiforme (GBM) has the highest rate of vascular proliferation among solid tumors. Angiogenesis is the central feature of rapid tumor growth in GBM and therefore remains an appealing therapeutic target in the treatment of these highly malignant tumors. Antiangiogenic therapy is emerging as an important adjuvant treatment.

Background: Bone morphogenetic protein-2 (BMP-2) is an available bone graft option in spinal fusion surgery. The purpose of this study is to investigate the trends of BMP-2 utilization in adult spinal deformity (ASD) surgery.

Methods: The Nationwide Inpatient Sample database from 2002 to 2011 was reviewed.

Study Design: Retrospective study of a prospectively collected database.

Objective: To investigate the rate and risk factors for 30-day readmissions and reoperations after 3-column osteotomy (3CO).

Methods: The American College of Surgeons National Surgical Quality Improvement Program database (2012-2014) was reviewed.

Objective: Somatosensory function is critical to normal motor control. After stroke, dysfunction of the sensory systems prevents normal motor function and degrades quality of life. Structural neuroplasticity underpinnings of sensory recovery after stroke are not fully understood.

Background: To identify predictive factors for critical care unit-level complications (CCU complication) after long-segment fusion procedures for adult spinal deformity (ASD).

Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database [2010-2014] was reviewed. Only adult patients who underwent fusion of 7 or more spinal levels for ASD were included.

Introduction: Sagittal synostosis affects 1 in 1000 live births and may result in increased intracranial pressure, hindrance of normal neural development, and cosmetic deformity due to scaphocephaly. Historically, several approaches have been utilized for surgical correction and recently, computed tomography (CT)-guided reconstruction procedures are increasingly used. In this report, the authors describe the use of a CT-derived virtual and stereolithographic (3D printed) craniofacial models, which are used to guide intraoperative bone placement, and intraoperative CT guidance for confirmation of bone placement, to ensure the accuracy of surgical correction of scaphocephaly, as demonstrated to parents.

Background: Intracavernous aneurysms constitute up to 9% of all intracranial aneurysms and 6% are infectious (IIA). First line therapy is a protracted antibiotic course, yet with failure, surgery and endovascular parent vessel sacrifice have been utilized. Reconstructive endovascular therapies have emerged for aneurysm control and may demonstrate a safer therapeutic alternative.

Background: Intracerebral ring enhancing lesions can be the presentation of a variety of pathologies, including neoplasia, inflammation, and autoimmune demyelination. Use of a precise diagnostic algorithm is imperative in correctly treating these lesions and minimizing potential adverse treatment effects.

Case Description: A 55-year-old patient presented to the hospital with complaints of a post-concussive syndrome and a non-focal neurologic exam.

Background: The relatively decreased time spent in the operating room and overall reduction in cases performed by neurosurgical trainees as a result of duty-hour restrictions demands that the pedagogical content within each surgical encounter be maximized and crafted toward the specific talents and shortcomings of the individual. It is imperative to future generations that the quality of training adapts to the changing administrative infrastructures and compensates for anything that may compromise the technical abilities of trainees. Neurosurgeons in teaching hospitals continue to experiment with various emerging technologies-such as simulators and virtual presence-to supplement and improve surgical training.

Cortical herniation through subdural membrane formation is a rare complication of chronic subdural fluid collections and may occur following subdural shunting. The authors present a unique case of progressive cortical herniation through a compressive subdural membrane that occurred concomitant with a functioning subdural-peritoneal shunt.
