Mashup Score: 10
OBJECTIVE This study was conducted to investigate the impact of antiplatelet administration in the periprocedural period on the occurrence of thromboembolic complications (TECs) in patients undergoing treatment using the Woven EndoBridge (WEB) device for intracranial wide-necked bifurcation aneurysms. The primary objective was to assess whether the use of antiplatelets in the pre- and postprocedural phases reduces the likelihood of developing TECs, considering various covariates. METHODS A retrospective multicenter observational study was conducted within the WorldWideWEB Consortium and comprised 38 academic centers with endovascular treatment capabilities. Univariable and multivariable logistic regression analyses were performed to determine the association between antiplatelet use and TECs, adjusting for covariates. Missing predictor data were addressed using multiple imputation. RESULTS The study comprised two cohorts: one addressing general thromboembolic events and consisting of 1

OBJECTIVE The recent introduction of the Woven EndoBridge (WEB) has presented an alternative treatment modality for intracranial bifurcation and wide-neck aneurysms with a growing body of literature evaluating its efficacy. However, no previous systematic review has focused on comparing WEB with previously using endovascular approaches, specifically primary coiling (PC) and stent-assisted coiling (SAC). Herein, the authors present the first systematic review summarizing available literature to reach a consensus regarding the safety and effectiveness of WEB. METHODS A systematic review of articles identified through a search of PubMed, Embase, Scopus, and Web of Science was conducted. Studies were included if they compared WEB with PC or SAC from any aspect for intracranial aneurysms. Risk of bias was assessed using the Risk of Bias in Non-Randomized Studies–of Interventions tool. Meta-analyses of the outcomes based on stent use and rupture status were performed. RESULTS A total of 16 s

Mashup Score: 12The impact of regular aspirin use on aneurysm recanalization rates after endovascular coiling - 1 month(s) ago
OBJECTIVE Intracranial aneurysms (IAs) pose a significant health risk, often leading to subarachnoid hemorrhage and severe neurological outcomes. Endovascular coiling has been a principal treatment method, but it comes with the challenge of high recanalization rates. Aspirin has recently emerged as a potential agent to reduce these rates. In this study, the authors aimed to investigate the impact of regular aspirin use on aneurysm recanalization rates following endovascular coiling in a 10-year single-institution study. METHODS A retrospective analysis was conducted on a dataset of 2236 aneurysms treated by a single neurosurgeon over a period of 10 years. The primary outcome measure was aneurysm recanalization, defined by a change in the Raymond-Roy Occlusion Classification of at least one grade. RESULTS A total of 525 aneurysms were coiled, 109 of which involved patients who reported regular use of aspirin. The recanalization rate was significantly lower in the aspirin group (9.2%) co

OBJECTIVE The primary aim of this retrospective study was to assess differences in the pathogens causing surgical site infections (SSIs) following craniectomies/craniotomies and open spinal surgery. The secondary aim was to assess differences in rates of SSI among these operative procedures. METHODS ANOVA tests with Bonferroni correction and incidence risk ratios (RRs) were used to identify differences in pathogens by surgical site and procedure using retrospective, de-identified records of 19,993 postneurosurgical patients treated between 2007 and 2020. RESULTS The overall infection rates for craniotomy/craniectomy, laminectomy, and fusion were 2.1%, 1.1%, and 1.5%, respectively, and overall infection rates for cervical, thoracic, and lumbar spine surgery were 0.3%, 1.6%, and 1.9%, respectively. Craniotomy/craniectomy was more likely to result in an SSI than spine surgery (RR 1.8, 95% CI 1.4–2.2, p < 0.0001). Cutibacterium acnes (RR 24.2, 95% CI 7.3–80.0, p < 0.0001); coagulase-negati

Mashup Score: 10The natural history of aneurysms incompletely occluded by placement of a flow diverter: a multiinstitutional study - 2 month(s) ago
OBJECTIVE Treatment of intracranial aneurysms by flow diversion is safe and effective and is increasingly popular. However, the correct treatment paradigm for aneurysms incompletely treated by initial placement of a flow diverter has not been established, nor have the subsequent natural history and occlusion rates of such aneurysms. The authors sought to outline the natural history of such aneurysms, which to date have been considered partially treated. METHODS The authors retrospectively reviewed consecutive cases from 6 high-volume neurointerventional services, including all cases in which the first follow-up imaging after placement of a flow diverter showed incomplete occlusion of the aneurysm, and for which subsequent clinical and/or radiological follow-up was available. All included patients were treated with the Pipeline Flex embolization device or the Pipeline Flex embolization device with Shield Technology. Subsequent radiographic and clinical outcome data were collected and an

OBJECTIVE Sagittal alignment measured on standing radiography remains a fundamental component of surgical planning for adult spinal deformity (ASD). However, the relationship between classic sagittal alignment parameters and objective metrics, such as walking time (WT) and grip strength (GS), remains unknown. The objective of this work was to determine if ASD patients with worse baseline sagittal malalignment have worse objective physical metrics and if those metrics have a stronger relationship to patient-reported outcome metrics (PROMs) than standing alignment. METHODS The authors conducted a retrospective review of a multicenter ASD cohort. ASD patients underwent baseline testing with the timed up-and-go 6-m walk test (seconds) and for GS (pounds). Baseline PROMs were surveyed, including Oswestry Disability Index (ODI), Patient-Reported Outcomes Measurement Information System (PROMIS), Scoliosis Research Society (SRS)–22r, and Veterans RAND 12 (VR-12) scores.

OBJECTIVE In this research, the authors sought to characterize the incidence and extent of cerebrovascular lesions after penetrating brain injury in a civilian population and to compare the diagnostic value of head computed tomography angiography (CTA) and digital subtraction angiography (DSA) in their diagnosis. METHODS This was a prospective multicenter cohort study of patients with penetrating brain injury due to any mechanism presenting at two academic medical centers over a 3-year period (May 2020 to May 2023). All patients underwent both CTA and DSA. The sensitivity and specificity of CTA was calculated, with DSA considered the gold standard. The number of DSA studies needed to identify a lesion requiring treatment that had not been identified on CTA was also calculated. RESULTS A total of 73 patients were included in the study, 33 of whom had at least 1 penetrating cerebrovascular injury, for an incidence of 45.2%. The injuries included 13 pseudoaneurysms, 11 major arterial occl

Mashup Score: 3Awake brain mapping paradigms for nondominant hemisphere gliomas - 4 month(s) ago
OBJECTIVE Traditionally, resection of nondominant hemisphere brain tumors was performed under general anesthesia. An improved understanding of right-lateralized neural networks has led to a paradigm shift in recent decades, where the right or nondominant hemisphere is no longer perceived as “functionally silent.” There is an increasing interest in awake brain mapping for nondominant hemisphere resections. The objective of this study was to perform a comprehensive review of the existing brain mapping paradigms for patients with nondominant hemisphere gliomas undergoing awake craniotomies. METHODS In accordance with PRISMA guidelines, systematic searches of the Medline, Embase, and American Psychological Association PsycInfo databases were undertaken from database inception to July 1, 2023. Studies providing a description of the intraoperative mapping paradigm used to assess cognition during an awake craniotomy for resection of a nondominant hemisphere glioma were included.

Mashup Score: 3Enhancing brain entry and therapeutic activity of chimeric antigen receptor T cells with intra-arterial NEO100 in a mouse model of CNS lymphoma - 5 month(s) ago
OBJECTIVE Malignancies of the CNS are difficult to treat because the blood-brain barrier (BBB) prevents most therapeutics from reaching the intracranial lesions at sufficiently high concentrations. This also applies to chimeric antigen receptor (CAR) T cells, for which systemic delivery is inferior to direct intratumoral or intraventricular injection of the cells. The authors previously reported on a novel approach to safely and reversibly open the BBB of mice by applying intra-arterial (IA) injections of NEO100, a pharmaceutical-grade version of the natural monoterpene perillyl alcohol. The authors hypothesized that this method would enable enhanced brain entry and therapeutic activity of intravenously delivered CAR T cells, which the authors tested in a mouse model of CNS lymphoma. METHODS Human Raji lymphoma cells were implanted into the brains of immune-deficient mice. After tumor uptake was confirmed with bioluminescent imaging, 0.3% NEO100 was injected intra-arterially, which was
