Aortoiliac occlusion mimicking cauda equina syndrome, a diagnostic dilemma: A case report and review of the literature.

Background: Cauda equina syndrome (CES) is a consequence of a variety of etiologies. CES is most commonly due to compression of the thecal sac and nerve roots by a massive disc herniation. However, it rarely presents secondary to aortic occlusion.

Impact of COVID-19 on Saudi Neurosurgery Residency: Trainers' and Trainees' Perspectives.

Introduction: After the official announcement of the coronavirus disease-19 pandemic on March 11, 2020, the disease impacted most aspects of health care delivery, especially postgraduate education and training.

Method: A cross-sectional, online questionnaire-based assessment was performed. The study participants involved neurosurgery residents and program directors (PDs) across the country between May 16 and May 27, 2020.

Vascular Eagle's Syndrome: Two Cases Illustrating Distinct Mechanisms of Cerebral Ischemia.

We report two cases of Vascular Eagle's Syndrome, which demonstrate two distinct mechanisms of cerebral ischemia. In the first case, hemodynamic transient cerebral ischemia arose as a direct result of compression of the internal carotid artery (ICA). In the second, embolic large left middle cerebral artery (MCA) infarction as a result of a thrombus from a pseudoaneurysmal dilatation of the left ICA.

Effects of decompressive craniectomy on functional outcomes and death in poor-grade aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis.

OBJECTIVE Patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH) (World Federation of Neurosurgical Societies Grade IV or V) are often considered for decompressive craniectomy (DC) as a rescue therapy for refractory intracranial hypertension. The authors performed a systematic review and meta-analysis to assess the impact of DC on functional outcome and death in patients after poor-grade aSAH. METHODS A systematic review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Predictors of Delayed Cerebral Ischemia in Patients with Aneurysmal Subarachnoid Hemorrhage with Asymptomatic Angiographic Vasospasm on Admission.

Background: Risk of delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH) with asymptomatic angiographic vasospasm on admission is unclear in the literature. The goal of this study is to identify predictors of clinical DCI in this group of patients.

Methods: An exploratory subgroup analysis was conducted in the SAHIT (Subarachnoid Hemorrhage International Trialists) data repository to identify predictors of clinical DCI in patients with good-grade aSAH (World Federation of Neurological Surgeons grade I and II) with angiographic vasospasm on admission.

Social Media Metrics and Bibliometric Profiles of Neurosurgical Departments and Journals: Is There a Relationship?

Background: Social media plays an increasingly important role in dissemination of knowledge and raising awareness of selected topics among the general public and the academic community.

Objective: To investigate the relationship between social media metrics and academic indices of neurosurgical programs and journals.

Methods: A 2-step online search was performed to identify official social media accounts of neurosurgical departments that were accredited by the Accreditation Council for Graduate Medical Education and the Royal College of Physicians and Surgeons of Canada.

Bridging the Gap between Evidence and Practice for Adults with Medically Refractory Temporal Lobe Epilepsy: Is a Change in Funding Policy Needed to Stimulate a Shift in Practice?

Objective. Surgery for medically refractory epilepsy (MRE) in adults has been shown to be effective but underutilized. Comprehensive health economic evaluations of surgery compared with continued medical management are limited.

A Practical Methodological Approach Towards Identifying Core Competencies in Medical Education Based on Literature Trends: A Feasibility Study Based on Vestibular Schwannoma Science.

Background: Competency-based medical education (CBME) is gaining momentum in postgraduate residency and fellowship training. While randomized trials, consensus statements, and practice guidelines can help delineate some of the core competencies for CBME, they are not applicable to all clinical scenarios.

Objective: To propose and assess the feasibility of a practical methodology for addressing this issue using radiosurgery for vestibular schwannoma (VS) science as an example.

Length of MRI signal may predict outcome in advanced cervical spondylotic myelopathy.

Objective: To study clinical and radiological factors that may correlate with independent walking (IW) following advanced cervical spondylotic myelopathy (CSM) surgery.

Methods: A retrospective case series including all advanced CSM patients (Nurick 4 and 5) who underwent surgery from 2003-2010 in the Division of Neurosurgery, Department of Surgery, College of Medicine, King Saud University and King Khalid University Hospital, Riyadh, Saudi Arabia. Only patients with 6 months or more follow-up were included.
