OBJECTIVE: Since the publication of A Randomized Trial of Unruptured Brain AVMs (ARUBA), the management of unruptured brain arteriovenous malformations (bAVMs) has been controversially discussed. Long-term follow-up data on the exclusively conservative management of unruptured bAVMs are scarce. The authors evaluated the long-term outcomes of patients with unruptured untreated bAVMs in a real-life cohort. METHODS: A retrospective observational cohort of 107 patients (of 897 bAVM patients referred to the authors' institution) with a diagnosis of unruptured and conservatively managed bAVMs is presented...

OBJECTIVE: Despite in utero spina bifida (SB) repair, more than two-thirds of patients with SB are unable to ambulate independently, and 1 in 4 children need surgery for tethered cord by school age. The objective of this study was to test the cryopreserved human umbilical cord (HUC) as an antiscarring material to reduce tethering and improve function in a modified in utero SB repair model. METHODS: An SB defect (L2-6 levels) without myelotomy was created in fetuses of timed-pregnant ewes at gestational day (GD) 75...

OBJECTIVE: The authors aimed to explore the feasibility and efficiency of an interrupted intraarterial selective cooling infusion (IA-SCI) combined with mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS). METHODS: This prospective, nonrandomized observational cohort study included consecutive patients with AIS who had undergone MT at a stroke center from December 2018 to April 2022. Subjects were classified into an interrupted IA-SCI group and MT-alone group...

OBJECTIVE: Surgery for giant diffuse lower-grade gliomas (LGGs) is challenging, and very few data have been reported on this topic in the literature. In this article, the authors investigated surgical, functional, and oncological aspects in patients who underwent awake resection for large LGGs with a volume > 100 cm3. METHODS: The authors retrospectively reviewed a consecutive cohort of patients who underwent surgery in an awake condition for an LGG (WHO grade 2 with possible foci of grade 3 transformation) with a volume > 100 cm3...

OBJECTIVE: The ability to predict final lesion characteristics during magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy for the treatment of essential tremor remains technically challenging, yet it is essential in order to avoid off-target ablation and to ensure adequate treatment. The authors sought to evaluate the technical feasibility and utility of intraprocedural diffusion-weighted imaging (DWI) in the prediction of final lesion size and location. METHODS: Lesion diameter and distance from the midline were measured on both intraprocedural and immediate postprocedural diffusion and T2-weighted sequences...

OBJECTIVE: Endonasal endoscopic odontoidectomy (EEO) is an alternative to transoral surgery for symptomatic ventral compression of the anterior cervicomedullary junction (CMJ), allowing for earlier extubation and feeding. Because the procedure destabilizes the C1-2 ligamentous complex, posterior cervical fusion is often performed concomitantly. The authors' institutional experience was reviewed to describe the indications, outcomes, and complications in a large series of EEO surgical procedures in which EEO was combined with posterior decompression and fusion...

OBJECTIVE: Preoperative differentiation of facial nerve schwannoma (FNS) from vestibular schwannoma (VS) can be challenging, and failure to differentiate between these two pathologies can result in potentially avoidable facial nerve injury. This study presents the combined experience of two high-volume centers in the management of intraoperatively diagnosed FNSs. The authors highlight clinical and imaging features that can distinguish FNS from VS and provide an algorithm to help manage intraoperatively diagnosed FNS...

OBJECTIVE: Newly diagnosed patients with a familial cavernous malformation (FCM) and their families are concerned about their future outlook, which is scarcely discussed in the literature. The authors studied a prospective contemporary cohort of patients with FCMs to assess demographics, mode of presentation, prospective risk of hemorrhage and seizures, need for surgery, and functional outcome over an extended interval. METHODS: A prospectively maintained database beginning January 1, 2015, of patients diagnosed with a cavernous malformation (CM) was queried...

OBJECTIVE: Timing of mobilization after chronic subdural hematoma (cSDH) surgery is highly heterogeneous among neurosurgical centers. Past studies have suggested that early mobilization may reduce medical complications without increasing recurrence, but evidence remains scarce. The purpose of this study was to compare an early mobilization protocol with a 48-hour bed rest practice, with a focus on the occurrence of medical complications. METHODS: The GET-UP Trial is a prospective, randomized, unicentric, open-label study with an intention-to-treat primary analysis designed to evaluate the impact of an early mobilization protocol after burr hole craniostomy for cSDH on the occurrence of medical complications and functional outcomes...

OBJECTIVE: Characterizing changes in the geographic distribution of neurosurgeons in the United States (US) may inform efforts to provide a more equitable distribution of neurosurgical care. Herein, the authors performed a comprehensive analysis of the geographic movement and distribution of the neurosurgical workforce. METHODS: A list containing all board-certified neurosurgeons practicing in the US in 2019 was obtained from the American Association of Neurological Surgeons membership database...

OBJECTIVE: Carotid stenosis can lead to both cognitive impairment (CI) and ischemic stroke. Although carotid revascularization surgery, which includes carotid endarterectomy (CEA) and carotid artery stenting (CAS), can prevent future strokes, its effect on cognitive function is controversial. In this study, the authors examined resting-state functional connectivity (FC) in carotid stenosis patients with CI undergoing revascularization surgery, with a particular focus on the default mode network (DMN)...

OBJECTIVE: The management of Spetzler-Martin grade (SMG) III brain arteriovenous malformations (bAVMs) may be challenging, whatever the exclusion treatment modality chosen. The purpose of this study was to evaluate the safety and effectiveness of endovascular treatment (EVT) as a first-line treatment of SMG III bAVMs. METHODS: The authors performed a retrospective, two-center, observational cohort study. Cases recorded in institutional databases between January 1998 and June 2021 were reviewed...

OBJECTIVE: Transfemoral access (TFA) has been the traditional route of arterial access for neurointerventional procedures. Femoral access site complications may occur in 2%-6% of patients. Management of these complications often requires additional diagnostic tests or interventions, each of which may increase the cost of care. The economic impact of a femoral access site complication has not yet been described. The objective of this study was to evaluate the economic consequences of femoral access site complications...

OBJECTIVE: The "presigmoid corridor" covers a spectrum of approaches using the petrous temporal bone either as a target in treating intracanalicular lesions or as a route to access the internal auditory canal (IAC), jugular foramen, or brainstem. Complex presigmoid approaches have been continuously developed and refined over the years, leading to great heterogeneity in their definitions and descriptions. Owing to the common use of the presigmoid corridor in lateral skull base surgery, a simple anatomy-based and self-explanatory classification is needed to delineate the operative perspective of the different variants of the presigmoid route...
