The effort required to introduce simulation in neurosurgery academic programs and the benefits perceived by residents have not been systematically assessed.To create a curriculum encompassing basic advanced skills, cadaveric dissection, cranial spine surgery simulation, endovascular computerized haptic training.A with 68 core exercises per year was distributed individualized sets of 30 simulations 6 residents. total number procedures completed during set 180. includes 79 physical models, 57...
Objective:This study explores the usefulness of virtual simulation training for learning to place pedicle screws in lumbar spine.Methods:Twenty-six senior medical students anonymously participated and were randomized into two groups (A = no simulation; B simulation). Both given 15 minutes a sawbones model. Students Group A underwent traditional visual/verbal instruction whereas on screw placement ImmersiveTouch® simulator. The both then placed each models that triplanar thin slice...
Background Flow-diverter stents (FDS) have become the standard of care for a wide range intracranial aneurysms, but their efficacy/safety in context recurrent/recanalized aneurysms following stent-assisted coiling (SAC) is not well established. We evaluate outcomes FDS retreatment large multicenter cohort. Methods retrospectively analyzed data from 118 patients across 22 institutions who underwent recurrent/persistent after SAC (2008–22). The primary outcome was angiographic occlusion status...
Remote tele-proctoring has been conducted in neuro-endovascular surgery, however, evidence to support its use the fellowship training is limited. We demonstrate a novel augmented reality platform enable remote attending guide fellow.A consecutive series of cases were performed by fellow with guidance from an surgeon. The and connected using commercially available cloud-based designed capture stream up four live video feeds clinical environment user. In this setting, two streams obtained...
Angioplasty and stenting is a treatment option for patients with medically refractory symptomatic intracranial atherosclerotic disease (sICAD). Currently the Wingspan Stent System (WSS) only FDA approved device this indication. We find Resolute (R) Onyx Stent, drug-eluting balloon mounted stent (DES), better alternative to WSS of sICAD. Herein, we present our findings comparing two stents based on single center experience.
We report two unusual cases of a 17-month-old boy with previously undiagnosed lumbar dermal sinus tract terminating in an intradural dermoid cyst and holocord edema or syrinx, presenting paraparesis sphincter dysfunction secondary to intramedullary abscess 26-month-old infected abscess, recurrent episodes meningitis hydrocephalus. Pre-operative magnetic resonance imaging (MRI) studies these patients were initially confused for spinal cord tumor; however, the presence associated made this...
Ruptured blister, dissecting, and iatrogenic pseudoaneurysms are rare pathologies that pose significant challenges from a treatment standpoint. Endovascular via flow diversion represents an increasingly popular option; however, drawbacks include the requirement for dual antiplatelet therapy potential thromboembolic complications, particularly acute complications in ruptured setting. The Pipeline Flex embolization device with Shield Technology (PED-Shield) offers reduced material...
OBJECT The authors have previously reported on their early experience with sublaminar polyester bands in spine surgery. In this paper, the describe use of long-segment posterior instrumented spinal fusions from upper thoracic to ilium 21 children and transitional adults progressive neuromuscular scoliosis. Transitional were patients older than 18 years age a disorder pediatric onset, such as spina bifida. This dedicated study represents first surgery for scoliosis patient population US....
Spinal arthrodesis was the first successful treatment for scoliosis, performed by Dr. Russell A. Hibbs in 1911 and later Fred H. Albee tuberculosis. In 1914, H.P.H. Galloway began using method to treat neuromuscular scoliosis patients with poliomyelitis. However, this approach plagued loss of deformity correction over time high pseudarthrosis rates.

Background We report the largest multicenter experience to date of utilizing Comaneci device for endovascular treatment refractory intracranial vasospasm. Methods Consecutive patients undergoing mechanical dilatation vasospasm were extracted from prospectively maintained registries in 11 North American centers (2020–2022). Intra-arterial vasodilators (IAV) allowed, with utilized after absence vessel dilation post-infusion. Pre- and post-vasospasm scores recorded each segment, primary...
Symptomatic intracerebral hemorrhage (sICH) after stroke is a devastating neurological complication. Current guidelines support "possible benefit" of decompressive craniectomy (DC) for large supratentorial sICH with significant mass effect.
The authors describe rare cases of congenital hypoplasia the L-5 pedicles and absence left S-1 pedicle in 2 young girls, respectively, including presentation, diagnosis, treatment. Moreover, they review literature on this clinical entity. patients presented with intractable chronic low-back pain. Plain radiographs 2D CT scanning revealed presence aforementioned anomalies. Degenerative changes to adjacent level contralateral facet joints were thought be result overload instability seemed have...
Developmental venous anomalies (DVA) are among the most common congenital malformations of cerebral angioarchitecture. Spontaneous thrombosis this entity is rare, and our review literature found only 31 reported cases symptomatic spontaneous developmental anomalies. Here, we report a unique case describing DVA leading to infarction subsequent recanalization. The patient was previously healthy 21-year-old male who presented with an acute onset partial seizures. Following negative...
<b>Aims:</b> Lateral transtemporal approaches are useful for addressing lesions located ventral to the brainstem, especially when pathologic diagnosis of tumor dictates that a gross or near total resection improves outcomes. One approach, presigmoid approach receives little attention in pediatric population thus far. We sought characterize morphometric changes, particularly clival depth and petroclival Cobb angle, occur temporal bones children draw implications about doing children....
Middle meningeal artery (MMA) embolization and the Subdural Evacuation Port System (SEPS) are minimally invasive treatment paradigms for chronic subdural hematoma (cSDH). Although SEPS offers acute decompression of local mass effect from a cSDH, MMA has been shown to reduce rate cSDH recurrence. In combination, these procedures present potentially safer strategy challenging pathology. The authors multi-institutional retrospective case series that assessed safety, efficacy, complications cSDH.
The use of intraoperative CT-guidance during the percutaneous treatment trigeminal neuralgia has become increasingly popular due to greater ease foramen ovale cannulation and decreased procedure times. Concerns regarding radiation dose patient, however, remain unaddressed. We sought compare emitted from fluoroscopy with CT for these procedures.A retrospective review lesioning procedures performed between 2010 until 2012 at our institution was conducted doses patient were recorded....
EMBOLISE (NCT04402632) is an ongoing randomized controlled trial investigating the safety and efficacy of middle meningeal artery embolization for treatment subacute or chronic subdural hematoma (SDH). Viz RECRUIT SDH artificial intelligence (AI)-based software platform that can automatically detect in noncontrast computed tomography (NCHCT) images report volume, maximum thickness, midline shift. We hypothesized mobile recruitment would aid enrollment coordinate communication image sharing...
Chronic subdural hematoma in children can be pathognomonic of abusive head trauma. Treatment options for these range from observation to surgical evacuation depending on clinical circumstance and presenting features, which include mental status changes, headaches, focal neurologic deficits, or asymptomatic presentation. Standalone endovascular treatments represent an area growing interest the adult population as effective treatment modality. However, embolization a singular approach has not...
Surgical resection is the current standard of therapy for treatment arteriovenous malformation (AVM). Endovascular embolization commonly used as an adjunct prior to surgical because it believed reduce risk intraoperative bleeding. Embolization has been associated with other complications including visual deficits, vessel perforation, and catheter adhesion. Catheter adhesion in which retained segments are contained within cast not necessarily cause concern, but retention larger portions may...
