BACKGROUND AND OBJECTIVES Stereotactic radiosurgery (SRS) marginal dose is associated with successful obliteration of cerebral arteriovenous malformations (AVM). SRS dose rate-how old the cobalt-60 sources are-is known to influence outcomes for some neurological conditions and benign tumors. The objective of this study was to determine the association between cobalt-60 treatment dose rate and cerebral

Association of Cerebrovascular Injury and Secondary Vascular Insult With Poor Outcomes After Gunshot Wound to the Head in a Large Civilian Population. Neurosurgery (IF 4.8) Pub Date : 2023-10-05 Jason J Lamanna,Juanmarco Gutierrez,Ali Alawieh,Chadd Funk,Rima S Rindler,Faiz Ahmad,Brian M Howard,Sanjay K Gupta,David A Gimbel,Randi N Smith,Gustavo Pradilla,Jonathan A Grossberg
BACKGROUND AND OBJECTIVES Cerebrovascular injury (CVI) after civilian gunshot wound to the head (GSWH) likely contributes to poor outcomes, but little supporting evidence exists. The purpose of this study was to determine whether intracranial CVI from GSWH and secondary vascular insult (stroke or rehemorrhage) were associated with poor outcomes in a large civilian population. METHODS This was a single-institution

Chinese Neurosurgical Randomized Controlled Trials: Dynamics in Trial Implementation and Completion. Neurosurgery (IF 4.8) Pub Date : 2023-10-05 Tao Liu,Mingqi Liu,Zhuang Sha,Chenrui Wu,Zhihao Zhao,Jiangyuan Yuan,Dongyi Feng,Meng Nie,Rongcai Jiang
BACKGROUND AND OBJECTIVES The focus on evidence-based neurosurgery has led to a considerable amount of neurosurgical evidence based on randomized controlled trials (RCTs) being published. Nevertheless, there has been no systematic appraisal of China's contribution to RCTs. Information about the changes in characteristics of Chinese neurosurgical RCTs before and during the COVID-19 pandemic is limited

Guidelines for Prehospital Management of Traumatic Brain Injury 3rd Edition: Executive Summary. Neurosurgery (IF 4.8) Pub Date : 2023-09-26 Gregory W J Hawryluk,Al Lulla,Randy Bell,Andy Jagoda,Halinder S Mangat,Bentley J Bobrow,Jamshid Ghajar
Prehospital care markedly influences outcome from traumatic brain injury, yet it remains highly variable. The Brain Trauma Foundation's guidelines informing prehospital care, first published in 2002, have sought to identify and disseminate best practices. Many of its recommendations relate to the management of airway, breathing and circulation, and infrastructure for this care. Compliance with the

Gender Differences in Procedural Clinical Complications and Outcomes of Intracranial Aneurysms: Analysis of the Stroke Thrombectomy and Aneurysm Registry. Neurosurgery (IF 4.8) Pub Date : 2023-09-25 Kazutaka Uchida,Hidetoshi Matsukawa,Mohammad-Mahdi Sowlat,Sameh Samir Elawady,Ali Alawieh,Pascal Jabbour,Justin Mascitelli,Michael R Levitt,Hugo Cuellar,Edgar A Samaniego,Peter Kan,Mark Moss,Alejandro M Spiotta,Shinichi Yoshimura
BACKGROUND AND OBJECTIVES Some studies have shown that female patients had a poorer prognosis after endovascular treatment for ruptured intracranial aneurysm than male patients. However, data have been sparse regarding differences in the periprocedural and perioperative complication rate with ruptured and unruptured intracranial aneurysms. METHODS This retrospective cohort study used data from the

Automated Preoperative and Postoperative Volume Estimates Risk of Retreatment in Chronic Subdural Hematoma: A Retrospective, Multicenter Study. Neurosurgery (IF 4.8) Pub Date : 2023-09-25 Jan Vargas,Matthew Pease,M Harrison Snyder,Jonathan Blalock,Shandong Wu,Enyinna Nwachuku,Aditya Mittal,David O Okonkwo,Ryan T Kellogg
BACKGROUND AND OBJECTIVES Several neurosurgical pathologies, ranging from glioblastoma to hemorrhagic stroke, use volume thresholds to guide treatment decisions. For chronic subdural hematoma (cSDH), with a risk of retreatment of 10%-30%, the relationship between preoperative and postoperative cSDH volume and retreatment is not well understood. We investigated the potential link between preoperative

Consensus-Based Development of a Global Registry for Traumatic Brain Injury: Establishment, Protocol, and Implementation. Neurosurgery (IF 4.8) Pub Date : 2023-09-25 Alexis J Joannides,Tommi K Korhonen,David Clark,Sujit Gnanakumar,Sara Venturini,Midhun Mohan,Thomas Bashford,Ronnie Baticulon,Indira Devi Bhagavatula,Ignatius Esene,Rocío Fernández-Méndez,Anthony Figaji,Deepak Gupta,Tariq Khan,Tsegazeab Laeke,Michael Martin,David Menon,Wellingson Paiva,Kee B Park,Jogi V Pattisapu,Andres M Rubiano,Vijaya Sekhar,Hamisi K Shabani,Kachinga Sichizya,Davi Solla,Abenezer
BACKGROUND AND OBJECTIVES Global disparity exists in the demographics, pathology, management, and outcomes of surgically treated traumatic brain injury (TBI). However, the factors underlying these differences, including intervention effectiveness, remain unclear. Establishing a more accurate global picture of the burden of TBI represents a challenging task requiring systematic and ongoing data collection

Global Outcomes for Microsurgical Clipping of Unruptured Intracranial Aneurysms: A Benchmark Analysis of 2245 Cases. Neurosurgery (IF 4.8) Pub Date : 2023-09-21 Richard Drexler,Thomas Sauvigny,Tobias F Pantel,Franz L Ricklefs,Joshua S Catapano,John E Wanebo,Michael T Lawton,Aminaa Sanchin,Nils Hecht,Peter Vajkoczy,Kunal Raygor,Daniel Tonetti,Adib Abla,Kareem El Naamani,Stavropoula I Tjoumakaris,Pascal Jabbour,Brian T Jankowitz,Mohamed M Salem,Jan-Karl Burkhardt,Arthur Wagner,Maria Wostrack,Jens Gempt,Bernhard Meyer,Michael Gaub,Justin R Mascitelli,Philippe
BACKGROUND AND OBJECTIVES Benchmarks represent the best possible outcome and help to improve outcomes for surgical procedures. However, global thresholds mirroring an optimal and reachable outcome for microsurgical clipping of unruptured intracranial aneurysms (UIA) are not available. This study aimed to define standardized outcome benchmarks in patients who underwent clipping of UIA. METHODS A total

Quantifying Patient-Initiated Upper Extremity Movement After Surgical Reconstruction for Adult Pan-Brachial Plexus Injury. Neurosurgery (IF 4.8) Pub Date : 2023-09-21 Whitney E Muhlestein,Tommy Nai-Jen Chang,Kate W-C Chang,Johnny Chuieng-Yi Lu,Pei-Ju Chen,Kevin C Chung,Lynda J-S Yang,Susan H Brown,David Chwei-Chin Chuang
BACKGROUND AND OBJECTIVES Determining functional recovery in adult patients with traumatic pan-brachial plexus injury (pBPI) is hampered by the fact that most outcome measures are collected in the clinical setting and may not reflect arm use in the real world. This study's objectives were to demonstrate the feasibility of using wearable motion sensor technology to quantify spontaneous arm movement

Thromboembolic Events With the Woven Endobridge Device: Incidence, Predictive Factors, and Management. Neurosurgery (IF 4.8) Pub Date : 2023-09-20 Fernanda Rodriguez-Erazú,Jonathan Cortese,Cristian Mihalea,Adrian Popica,Vanessa Chalumeau,Natalia Vasconcellos,Sophie Gallas,Leon Ikka,Lamiae Grimaldi,Jildaz Caroff,Laurent Spelle
BACKGROUND AND OBJECTIVES The Woven EndoBridge (WEB) device has been increasingly used to treat wide-neck aneurysms showing a safe and effective profile, but a relatively high number of thromboembolic events (TEEs) have been reported with such treatment. We aimed to evaluate the incidence and management of TEEs and possible predictive factors related to WEB embolization of ruptured and unruptured intracranial
