Emergence of the novel corona virus (severe acute respiratory syndrome (SARS)-CoV-2) in December 2019 has led to COVID-19 pandemic. The extent involvement central nervous system is not well established, and presence or absence SARS-CoV-2 particles cerebrospinal fluid (CSF) a topic debate.We present two patients with concurrent neurological symptoms. Our first patient 31-year-old man who had flu-like symptoms due later developed an acute-onset severe headache loss consciousness was diagnosed...
Robots in surgery aid performing delicate, precise maneuvers that humans, with inherent physical abilities, may be limited to perform. The CorPath 200 system is FDA approved and being implemented the US for interventional cardiology procedures. GRX robotic-assisted platform next-generation successor of 200.To discuss feasibility early experience use neuroendovascular procedures, including transradial diagnostic cerebral angiograms carotid artery stenting.The cases 10 consecutive patients who...
Background Endovascular embolization of the middle meningeal artery (MMA) has emerged as an adjunctive and stand-alone modality for management chronic subdural hematomas (cSDH). We report our experience utilizing proximal MMA coil to augment cSDH devascularization in embolization. Methods cases with coiling were retrospectively identified from a prospectively maintained IRB-approved database senior authors. Results Of 137 cases, all patients (n = 89, 100%) symptomatic underwent procedure...
Background Monocular vision loss, attributed to either central retinal artery occlusion ( CRAO ), branch BRAO or ocular ischemic syndrome OIS is thought be associated with an increased prevalence of cerebral infarcts. However, there a paucity data substantiating this. We aimed investigate this relationship in Canadian center and further understand the importance internal carotid stenosis potential clinical decision making. Methods Results performed retrospective cohort study at comprehensive...
With increasing use of endovascular techniques in the treatment ruptured and unruptured aneurysms, issue obliteration efficacy has become increasingly important. We have previously reported Aneurysm Recanalization Stratification Scale, which uses accessible predictors including aneurysm-specific factors (size, rupture, intraluminal thrombosis) treatment-related features (treatment modality immediate angiographic result) to predict retreatment risk after therapy.To assess external validity...
The advent of metal flow-diverting stents has provided neurointerventionalists with an option for treating aneurysms without requiring manipulations within the aneurysm sac. large amount in these stents, however, can lead to early and late thrombotic complications, thus requires long-term antiplatelet agents. Bioabsorbable have been postulated mitigate risk complications. Here we present data on first self-expandable primarily bioabsorbable stent aneurysms.Braided were developed using...
In this study, the authors aimed to investigate procedural and clinical outcomes between radial femoral artery access in patients undergoing thrombectomy for acute stroke.
Background The COVID-19 pandemic forced a reconsideration of surgical patient management in the setting scarce resources and risk viral transmission. Herein we assess impact implementing protocol more rigorous education, recovery room assessment for non-ICU admission, earlier mobilization post-discharge communication patients undergoing brain tumor surgery. Methods A case-control retrospective review was undertaken at community hospital with dedicated neurosurgery otolaryngology team using...
OBJECTIVE The authors’ objective was to compare the indications, outcomes, and anatomical limits of supraorbital (SO) mini-pterional (MP) craniotomies in patients with intra- extraaxial brain tumors, assess approach selection, utility endoscopy, surgical field overlap. METHODS A retrospective analysis conducted all tumor who underwent an SO or MP approach. analyzed characteristics included pathology, endoscopy use, extent resection, length stay (LOS), complications. On basis preoperative MRI...

Introduction Dural venous sinus stenosis (DVSS) may lead to increased intracranial pressure, sometimes requiring a stent if high pressure gradient exists. Many neuroendovascular physicians use microcatheters measure gradients, yet there are no studies comparing the accuracies and precisions of modern day microcatheters. We examined recordings from five commonly used in an experimental DVSS model. Methods Using programmable pump, dynamic flow was established closed circuit mimicking waveform....
Abstract BACKGROUND The transradial access (TRA) is rapidly gaining popularity for neuroendovascular procedures as there strong evidence its benefits compared to the traditional transfemoral (TFA). However, transition TRA bears some challenges including optimization of interventional suite set-up and workflow well impact on fellowship training. OBJECTIVE To compare learning curves TFA diagnostic cerebral angiograms in METHODS We prospectively collected angiogram procedural data performance 2...
In endoscopic endonasal approaches (EEAs) for skull base pathologies, endoscope view obscuration remains a persistent, time-consuming, and distracting issue surgeons may result in increased operative time. The access guide (EAG) has been demonstrated as possible adjunct to minimize these events. However, date, there have no comparative studies performed the potential time savings by using EAGs yet be quantified. This cohort study aimed determine efficiency benefits of EAG EEA operations.
Reliable animal models are an important aspect of translational research, especially for relatively uncommon clinical entities such as fusiform aneurysms. While several exist, very few tailored to cerebral aneurysms, which have unique attributes compared abdominal The authors aimed build from previous create a aneurysm model that is simple use and reliable.
Abstract Neuroangiography has seen a recent shift from transfemoral to transradial access. In neuroangiography, the right dominant hand is main access used. However, left side may be used specifically for posterior circulation pathologies and when cannot This study describes our initial experience with radial diagnostic neuroangiography assesses feasibility safety of this technique. We performed retrospective review prospective database consecutive patients between April 2018 January 2020,...
Several studies have demonstrated a potential interaction between mesenchymal stem cells (MSCs) and saccular aneurysms. In this study, we sought to determine whether allogenic bone marrow-derived MSCs had the ability prevent aneurysm formation in known rabbit elastase model. were injected intravenously experimental rabbits at time of surgical creation two weeks postcreation compared with control receiving vehicle injection. Angiography was used compare measurements four postcreation,...
Indocyanine green (ICG) videoangiography is an intraoperative technique recently used in vascular neurosurgery to assess the presence or absence of blood flow during critical times a procedure. These include, but are not limited to, detecting whether daughter branches perforators patent after placing clip determining aneurysm has been completely isolated from cerebral circulation clipping. We present case less-commonly reported application ICG involving selection vessel act as bypass...
Cavernous haemangiomas, or cavernous malformations, have been reported during pregnancy, most of which either supratentorial spinal lesions. We encountered a 15-year old pregnant patient with rapidly progressive and haemorrhagic brainstem haemangioma. The case presented here describes the history findings this patient, as well less-commonly utilized technique we used to access floor fourth ventricle via occipital craniotomy for complete macroscopic resection lesion, resulting in gradual...
Though endometrial carcinomas are a relatively common cancer of the female genitourinary tract, they rarely metastasize. Similarly, clival metastases make up tiny fraction all brain metastases. To authors' knowledge, an carcinoma metastasis has never been described in literature; therefore, authors present following unusual case 69-year-old with history initially grade 2 adenocarcinoma that metastasized to her clivus.
