Background: This study aims to address the safety and efficacy of mechanical thrombectomy (MT) in acute ischemic stroke with an established infarction equal to or >50 mL with a significant difference between penumbra and established infarction detected by perfusion cerebral computed tomography (CT) with the Rapid system.
Methods: This was a retrospective case-control study. Patients diagnosed with established and extensive ischemic stroke, defined by an ischemic volume equal to or >50 mL on CT or magnetic resonance imaging perfusion using the RAPID system, were examined.
Introduction: Mechanical thrombectomy (MT) has changed the standard of care for patients presenting with acute ischemic stroke (AIS). The window of treatment has significantly increased the number of patients who would benefit from intervention and operators may be confronted with patients harboring preexistent neurological disorders. Still, the epidemiology of patients with AIS and neurological disorders has not been established.

However, the systemic inflammatory nature of these disease processes often necessitates therapy with disease-modifying antirheumatic drugs (DMARDs). Alteration of these agents in the perioperative period for surgery requires a careful risk-benefit analysis to limit disease flares, infection rates, and secondary revisions.

TLICS is one of the few classifications that provides treatment recommendations.We sought to analyze intervention modality selection based on the TLICS scoring system.

This systematic review and meta-analysis aims to assess the current evidence regarding favorable outcome as measured by Glasgow Outcome Scale (GOS) scores following treatment of PTV.
Methods: A systematic review of PubMed, Ovid MEDLINE, and Ovid EMBASE was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
Background And Objective: For chronic subdural hematoma (cSDH), bedside subdural drains (SDD) provide a useful alternative to more invasive neurosurgical techniques, including evacuation through multiple burr holes or formal craniotomy. However, no scale currently exists adequately predicting SDD candidacy or treatment response. The present study sought to characterize predictors of revision surgery after initial treatment with bedside SDD for cSDH.

Early intervention is necessary to halt progression of disease and minimize irreversible dysfunction. We sought to characterize initial treatment success and recurrence rates following interventional treatment of various types of SVMs.

Neurostimulation is a potentially useful treatment option, should the neuropathic pain remain refractory to more invasive procedures such as orchiectomy. We provide a case report of spinal cord stimulation (SCS) for successful treatment of genitofemoral neuropathy and have also reviewed the literature to find similar cases which required a similar treatment paradigm.

Utilization of endovascular techniques for aneurysm repair increased dramatically during the last decade. We sought to analyze recent national trends for electively treated (open and endovascular) UIAs focusing on pre-existing patient disease burden and intervention modality selection.
View Article and Find Full Text PDFObjective: Super-refractory status epilepticus (SRSE) is a neurologic emergency with high mortality and morbidity. Although medical algorithms typically are effective, when they do fail, options may be limited, and neurosurgical intervention should be considered.
Methods: We report a case of SRSE treated acutely with responsive neurostimulation (RNS) and focal surgical resection after intracranial monitoring.
Purpose: To determine whether the published literature supports the current practice of utilizing antibiotics postoperatively in spine surgery.
Methods: A systematic review from PubMed and Cochrane Central Register of Controlled trials databases was performed. Search terms used: "Antibiotic Prophylaxis"[Mesh], antibiotic*, antibacterial*, "Spine"[Mesh], "Surgical Procedures, Operative"[Mesh].
Background: Ischemic stroke is a frequently encountered neurologic process with wide-spanning impact. A dreaded complication is "malignant" cerebral edema, necessitating decompression to reduce herniation risk. Following the publication of several landmark trials in 2015, endovascular thrombectomy (EVT) with novel clot-removal devices has emerged as an effective treatment for proximal large vessel disease.

The present review aims to describe the current status of intraoperative AR for the treatment of cerebrovascular pathology. A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
View Article and Find Full Text PDFBackground: In preparation for surgery, patients being treated with disease-modifying antirheumatic drugs (DMARDs) are recommended to either continue or withhold therapy perioperatively. Some of these drugs have known effects against bone healing, hence the importance of adequately managing them before and after surgery.
Objective: We aim to assess the current evidence for managing conventional synthetic and/or biologic DMARDs in the perioperative period for elective spine surgery.
Seizures are common presenting symptoms of intracranial arteriovenous malformations (AVMs). This systematic review and meta-analysis aims to assess the current evidence regarding complete seizure freedom rates following surgical resection, stereotactic radiosurgery (SRS), and/or endovascular embolization of intracranial AVMs. A systematic review of PubMed, Ovid MEDLINE, and Ovid EMBASE was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Several smaller studies are available using 3D printing; however, there is a lack of a concise review. This article provides a systematic review of 3D models in use by neurosurgical residents, with emphasis on training, learning, and simulation.

Objective: The objective of this study was to evaluate the rate of dysphagia for Parkinson disease (PD) patients undergoing cervical spine surgery for cervical myelopathy.
Summary Of Background Data: Cervical spondylotic myelopathy (CSM) is an increasingly common problem in the aging population.
Background: Carotid cavernous fistulas (CCFs) are pathologic connections between the carotid arteries and the cavernous sinus and have been classically treated with endovascular coil embolization, although flow diverters have been used for treatment successfully multiple times. The aim of this study is to systematically review the literature for efficacy of flow diverters in treating CCFs.
Methods: A systematic review was conducted using the PRISMA guidelines.
Purpose: Thromboembolic events represent the most common procedure-related complication associated with neurointerventions. Cangrelor is a potent, intravenous (IV), P2Y12-receptor antagonist with a rapid onset and offset presented as an alternative antiplatelet agent. We aim to evaluate the safety and effectiveness of IV cangrelor in neurovascular intervention.

Methods: All patients undergoing ventriculoperitoneal shunt creation between November 2013 and September 2017 at a single academic institution were evaluated.
Introduction: Wide-necked intracranial aneurysms (IAs) are complex lesions that may require different microsurgical or endovascular strategies, and stent-assisted coiling (SAC) has emerged as a feasible alternative to treat this subset of aneurysms.
Methods: The objective was to assess the rate of complications of unruptured wide-necked IAs treated with SAC. We retrospectively identified patients with unruptured wide-necked IAs treated with SAC.

Objective: Surgical performance evaluation was first described with the OSATS (Objective Structured Assessment of Technical Skills) and modified for aneurysm microsurgery simulation with the OSAACS (Objective Structured Assessment of Aneurysm Clipping Skills). These methods rely on the subjective opinions of evaluators, however, and there is a lack of objective evaluation for proficiency in the microsurgical treatment of brain aneurysms. The authors present a new instrument, the Skill Assessment in Microsurgery for Brain Aneurysms (SAMBA) scale, which can be used similarly in a simulation model and in the treatment of unruptured middle cerebral artery (MCA) aneurysms to predict surgical performance; the authors also report on its validation.
