Objective: Endovascular intracranial aneurysm (IA) management has significantly evolved over the last 2 decades. Despite these advancements, the aneurysm recanalization rate after coil embolization remains a concern. Statins have been found to affect vascular repair and remodeling; therefore, the authors hypothesized that patients receiving statin therapy at the time of coil embolization would have lower aneurysm recurrence and retreatment rates compared with patients not receiving statin therapy.

Background And Objectives: Histologic and transcriptomic analyses of retrieved stroke clots have identified features associated with patient outcomes. Previous studies have demonstrated the predictive capacity of histology or expression features in isolation. Few studies, however, have investigated how paired histologic image features and expression patterns from the retrieved clots can improve understanding of clot pathobiology and our ability to predict long-term prognosis.

Background And Objectives: The performance of select neurosurgical procedures is being transitioned to an outpatient setting rather than an inpatient setting to increase healthcare cost-effectiveness. Despite numerous technological advancements in the treatment of unruptured intracranial aneurysms (UIAs), the procedures are solely performed in an inpatient setting. We aimed to compare the rate of short-term outcomes associated with inpatient endovascular treatment of UIAs with those for established outpatient neurosurgical procedures, including anterior cervical discectomy and fusions (ACDFs) and lumbar discectomies.

Background: The EXCELLENT registry aimed to evaluate the effectiveness of the EMBOTRAP Revascularization Device in an all-comer population in a real-world setting, with a focus on the composition of retrieved clots.

Methods: EXCELLENT is a prospective, global registry of patients with acute ischemic stroke treated with EMBOTRAP as the first-line mechanical thrombectomy device conducted at 34 sites (25 sites contributing clot) from September 2018 to March 2021, utilizing core imaging and central histology laboratories blinded to clinical data, independent 90-day modified Rankin Scale assessment and Clinical Events Committee.

Results: After screening 3799 patients, a total of 997 subjects (mean age, 70.

Background: The Woven EndoBridge (WEB) is a treatment modality available for the treatment of intracranial aneurysms, specifically beneficial in wide-necked bifurcation aneurysms. Conventional sizing methods rely on the manipulation of aneurysm width and height measurements. This results in frequent need for re-sizing after initial WEB insertion attempts.

Objective: The authors sought to quantify the role of social media-related academic activity through use of the Altmetric score (a composite score based on social media attention from a variety of sources) and investigate its potential impact on the number of citations received at 3 years postpublication (articles published between January 2019 and December 2019).

Methods: Articles published in the top 12 neurosurgical journals according to Google Scholar (based on 5-year Web of Science impact factors, 2017-2021) were identified. Data collected included days since publication, Altmetric scores, and total number of tweets (posts), and 3-year citations were obtained from Google Scholar.

Background: Utilizing an endovascular rat glioma model, this study aimed to analyze the efficacy of intra-arterial (IA) carboplatin and bevacizumab delivery with blood-brain barrier breakdown (BBBB) for glioblastoma treatment.

Methods: C6-glioma cells were stereotactically injected into the left frontal lobe of Wistar rats. Tumor growth was confirmed on day 8 via MRI.

Background And Objective: Ambulatory surgery centers (ASCs) are increasingly common venues for same-day neurosurgical procedures, allowing for cost-effective, high-quality patient care. We present the first and largest series of patients undergoing diagnostic cerebral angiography at an ASC to demonstrate the effectiveness, safety, and efficiency of outpatient endovascular care.

Methods: We retrospectively reviewed data for consecutive patients who underwent diagnostic cerebral angiography at our ASC between January 1, 2024, and May 29, 2024.

Article Synopsis
  • - The study compared the effectiveness and safety of four first-generation flow diverters (FDs) used for treating sidewall ICA intracranial aneurysms, which include Pipeline, Silk, FRED, and Surpass devices, using data from 444 patients across 18 institutions from 2009-2016.
  • - Analysis revealed no significant differences in retreatment rates or complications among the devices; however, the Surpass device showed the highest probability of achieving effective occlusion at follow-up, followed by FRED, Pipeline, and Silk.
  • - Although all devices had good clinical outcomes, the study highlights the need for prospective research to further clarify the differences and long-term effects of these flow diverters.

Background: With transradial access (TRA) being more progressively used in neuroendovascular procedures, we compared TRA with transfemoral access (TFA) in middle meningeal artery embolization (MMAE) for chronic subdural hematoma (cSDH).

Methods: Consecutive patients undergoing MMAE for cSDH at 14 North American centers (2018-23) were included. TRA and TFA groups were compared using propensity score matching (PSM) controlling for: age, sex, concurrent surgery, previous surgery, hematoma thickness and side, midline shift, and pretreatment antithrombotics.

Article Synopsis
  • * Researchers conducted a review of procedures performed at their center from 2004 to 2022, involving 55 pediatric patients who had various vascular conditions, such as aneurysms and arteriovenous malformations.
  • * Results showed a low rate of complications, with only 1.7% experiencing access-site issues and a 1.8% rate of treatment-related mortality, suggesting that neurointerventions can be safely carried out in pediatric patients.

Aneurysm wall enhancement (AWE) has the potential to be used as an imaging biomarker for the risk stratification of intracranial aneurysms (IAs). Radiomics provides a refined approach to quantify and further characterize AWE's textural features. This study examines the performance of AWE quantification combined with clinical information in detecting symptomatic IAs.

Objective: Neurosurgeons demonstrate some of the highest levels of burnout among surgeons, yet little research has been done to understand the underlying stressors that neurosurgeons and trainees experience and the emotional responses to them. Our goal was to conduct a feasibility study identifying job stressors and emotional responses among neurosurgeons rather than generalize findings across the profession.

Methods: Emphasizing a qualitative approach in this feasibility and descriptive study, we strategically selected a small sample of neurosurgical attendings, residents, and fellows at 2 United States academic neurosurgical departments to ensure an in-depth analysis laying the groundwork for future extensive research.

Background: Transcriptomic profiling has emerged as a powerful tool for exploring the molecular landscape of ischemic stroke clots and providing insights into the pathophysiological mechanisms underlying stroke progression and recovery. In this study, we aimed to investigate the relationship between stroke clot transcriptomes and stroke thrombectomy outcome, as measured by early neurological improvement (ENI) 30 (i.e.

Objective: Aneurysmal subarachnoid hemorrhage (aSAH) is associated with high mortality rates. There is a significant gap in the literature describing global disparities in demographics, management, and outcomes among patients with aSAH. We aimed to conduct a systematic review and meta-analysis to assess global disparities in aSAH presentation and management.

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.
