Novel Radiologic Parameter to Simulate Decompression Efficacy in Cervical Laminoplasty: The Magnetic Resonance Imaging Laminar Line

模拟颈椎椎板成形术减压效果的新型影像学参数：磁共振成像椎板线

The goal of this study was to investigate the clinical value of magnetic resonance imaging (MRI) laminar line (LL)-simulated decompression for predicting the efficacy of cervical laminoplasty (CLP). The application of MRI LL-simulated decompression can predict radiological outcomes of spinal cord decompression and aid in the preoperative planning of CLP.

本研究的目的是探讨磁共振成像（MRI）层状线（LL）模拟减压在预测颈椎板成形术（CLP）疗效方面的临床价值。应用MRI LL模拟减压可预测脊髓减压的影像学结果，并有助于CLP的术前规划。

Clinical Classification of Adolescent Cervicothoracic Hemivertebra Treated with Surgical Intervention Incorporating Shoulder Balance Considerations

结合肩部平衡考量手术治疗青少年颈胸段半椎体的临床分类

Achieving shoulder balance is a critical factor in evaluating the outcomes of cervicothoracic hemivertebra surgery in adolescents. Current classification systems for hemivertebrae fail to adequately consider shoulder balance. This study introduces a novel classification system for adolescent cervicothoracic hemivertebrae, incorporating both the positional characteristics of the hemivertebrae and an assessment of shoulder balance. This classification system provides spinal surgeons with a structured framework to achieve optimal curve correction and postoperative shoulder balance during hemivertebra resection. Its high interobserver reproducibility and intraobserver reliability establish it as an invaluable tool for guiding the surgical treatment of adolescent cervicothoracic hemivertebrae in clinical practice.

实现肩部平衡是评估青少年颈胸椎半椎体手术效果的关键因素。目前的半椎体分类系统未能充分考虑肩部平衡。本研究引入了一种针对青少年颈胸椎半椎体的新型分类系统，该系统既考虑了半椎体的位置特征，又对肩部平衡进行了评估。这一分类系统为脊柱外科医生提供了一个结构化的框架，有助于在半椎体切除术中实现最佳的脊柱侧弯矫正和术后肩部平衡。其较高的观察者间可重复性和观察者内可靠性使其成为临床实践中指导青少年颈胸椎半椎体手术治疗的宝贵工具。

Higher Improvement in Oswestry Disability Index Is Appropriate to Increase Satisfaction of Frail Patients After Lumbar Fusion Surgery

奥斯特里残疾指数的更大改善有助于提高腰椎融合手术后虚弱患者的满意度

To determine extent of improvement in the Oswestry Disability Index (ODI) required to achieve patient satisfaction among frail patients undergoing lumbar fusion surgery. Frail patients with lower preoperative ODI were significantly more likely to experience postoperative satisfaction, whereas nonfrail/prefrail patients with higher preoperative ODI were significantly more likely to experience postoperative satisfaction. Among frail patients, relative ODI improvement ≥67% or postoperative ODI ≤17 indicated patient satisfaction; in nonfrail/prefrail patients, relative ODI improvement ≥55% or postoperative ODI ≤26 indicated patient satisfaction.

确定接受腰椎融合手术的虚弱患者达到患者满意度所需的Oswestry功能障碍指数（ODI）改善程度。术前ODI较低的虚弱患者术后更有可能感到满意，而术前ODI较高的非虚弱/前虚弱患者术后更有可能感到满意。在虚弱患者中，相对ODI改善≥67%或术后ODI≤17表明患者满意；在非虚弱/前虚弱患者中，相对ODI改善≥55%或术后ODI≤26表明患者满意。

Endovascular Management and Long-Term Outcomes of Aneurysmal Subarachnoid Hemorrhage Among a Large Cohort of Patients Managed at a Specialist Hospital in KwaZulu-Natal, South Africa from 2012 to 2021

2012年至2021年南非夸祖鲁 - 纳塔尔省一家专科医院收治的大批动脉瘤性蛛网膜下腔出血患者的血管内治疗及长期预后情况

Aneurysmal subarachnoid hemorrhage (aSAH) is a severe stroke subtype with high morbidity and mortality, particularly in low- and middle-income countries. Endovascular treatment is underused in Africa due to resource constraints. This study evaluates clinical characteristics, radiological findings, treatment outcomes, and long-term follow-up of aSAH patients treated endovascularly at a South African quaternary hospital. This study, the largest in an African cohort, confirms safety, efficacy, and durability of endovascular management of aSAH in resource-constrained settings, supporting its expansion in Africa.

动脉瘤性蛛网膜下腔出血（aSAH）是一种严重的卒中亚型，发病率和死亡率都很高，在低收入和中等收入国家尤为如此。由于资源限制，血管内治疗在非洲未得到充分应用。本研究评估了南非一家四级医院接受血管内治疗的aSAH患者的临床特征、影像学表现、治疗结局和长期随访情况。这项针对非洲人群开展的规模最大的研究证实，在资源有限的环境下，血管内治疗aSAH具有安全性、有效性和持久性，支持在非洲扩大该治疗方法的应用。

Synovial Cyst of Thoracic Spine: A Systematic Literature Review and Meta-Analysis

胸椎滑膜囊肿：系统文献综述与荟萃分析

Thoracic spine synovial cysts (TSSC) are rare. Only case reports and a few small series, but no systematic review, have been published so far. This article aimed to update all the TSSC cases and analyze data in addition to reporting three cases. TSSC are more common in elderly males, mostly occur in the lower thoracic spine, below T7. Most of them present with myelopathy and motor weakness and are cured with resection of the cyst without the need for spinal fusion. There was no report of recurrence or revision surgery.

胸椎滑膜囊肿（TSSC）较为罕见。截至目前，仅有病例报告和少数小规模系列研究发表，尚无系统综述。本文旨在更新所有TSSC病例并分析数据，同时报告三例病例。TSSC在老年男性中更为常见，大多发生于胸椎下段（T7以下）。大多数患者表现为脊髓病和运动无力，切除囊肿即可治愈，无需进行脊柱融合手术。目前尚无复发或翻修手术的报告。

The Risk of Dysphagia After Short-Segment Posterior Occipital-C2 Fusion versus C1-C2 Cervical Fusion: A Retrospective Cohort Study

短节段枕骨 - C2 后路融合与 C1 - C2 颈椎融合术后吞咽困难的风险：一项回顾性队列研究

We examined whether short-segment posterior occipital-C2 (O-C2) fusion is associated with a higher risk of postoperative dysphagia than short-segment posterior C1-C2 fusion to enhance preoperative education and shared decision-making. Compared to C1-C2 fusion, O-C2 fusion was associated with a nearly 2-fold increase in risk of dysphagia through 2 years, along with potential increases in other oropharyngeal and respiratory complications. Surgeons should be aware of these findings when planning O-C2 versus C1-C2 fusion.

我们研究了短节段枕骨 - 颈椎 2（O - C2）后路融合术相比短节段颈椎 1 - 颈椎 2（C1 - C2）后路融合术是否与术后吞咽困难的更高风险相关，以加强术前教育和共同决策。与 C1 - C2 融合术相比，O - C2 融合术在术后两年内吞咽困难的风险增加了近一倍，同时其他口咽和呼吸并发症的风险也可能增加。外科医生在规划进行 O - C2 融合术还是 C1 - C2 融合术时应了解这些研究结果。

Risk Factor Analysis of Transient Ischemic Attack for Moyamoya Disease After a First Combined Revascularization Surgery

首次联合血管重建术后烟雾病发生短暂性脑缺血发作的危险因素分析

This study aims to elucidate the characteristics and risk factors for transient ischaemic attack (TIA) after the combined revascularization surgical procedure for first diagnosed Moyamoya disease patients. Patients who experienced TIA had a relatively high risk of progressing to stroke, which was associated with preoperative SBP-ARV and MAP-ARV.

本研究旨在阐明初诊烟雾病患者接受联合血管重建手术后短暂性脑缺血发作（TIA）的特征及危险因素。发生TIA的患者进展为中风的风险相对较高，这与术前收缩压变异性幅度（SBP - ARV）和平均动脉压变异性幅度（MAP - ARV）有关。

Predictors of Transradial Cerebral Angiography Failure and Comparative Outcomes with the Transfemoral Approach: A Single-Center, 5-Year Retrospective Study

经桡动脉脑血管造影失败的预测因素及与经股动脉入路的对比结果：一项单中心5年回顾性研究

Transradial cerebral angiography (TRCA) is increasingly favored over transfemoral cerebral angiography (TFCA) due to lower complication rates and improved patient comfort, despite anatomical and procedural challenges. This study aimed to assess factors influencing TRCA failure and compare clinical outcomes between TRCA and TFCA in patients undergoing diagnostic cerebral angiography at a single institution. TRCA holds promise as a standard approach in neurointervention, but proficiency in both TRCA and TFCA remains essential. Radial artery issues and prolonged procedure time are significant predictors of TRCA failure. Optimizing TRCA outcomes requires meticulous preprocedural aortic arch evaluation, enhanced operator experience, and continuous technical refinements.

经桡动脉脑血管造影（TRCA）尽管存在解剖和操作方面的挑战，但由于其并发症发生率较低且患者舒适度更高，相较于经股动脉脑血管造影（TFCA）越来越受到青睐。本研究旨在评估影响TRCA失败的因素，并比较在单一机构接受诊断性脑血管造影的患者中TRCA和TFCA的临床结局。TRCA有望成为神经介入领域的标准方法，但熟练掌握TRCA和TFCA仍然至关重要。桡动脉问题和手术时间延长是TRCA失败的重要预测因素。要优化TRCA的治疗效果，需要在术前对主动脉弓进行细致评估、提高术者经验并持续改进技术。

Clinical Outcome of Redo-Surgery for Recurrent Chronic Subdural Hematoma: A Systematic Review and Meta-Analysis Combined with a Case Series

复发性慢性硬膜下血肿再次手术的临床结局：一项系统评价和Meta分析结合病例系列研究

Chronic subdural hematoma (CSDH) is becoming more prevalent, particularly in aging populations, with a 20% recurrence rate postsurgery. Burr hole craniostomy is the standard treatment, but recurrence remains a significant challenge. This study evaluates the incidence of second CSDH recurrence, its management, and clinical outcomes following various hematoma evacuation procedures in the literature and our cohort. Redo-surgery is currently the primary treatment for (subsequent) recurrent CSDH and leads to unfavorable outcomes. Given the high recurrence rates and poor functional recovery, there is a need for improved treatment approaches to address the underlying pathophysiology of CSDH. Further research is needed to evaluate the effectiveness of middle meningeal artery embolization in the context of recurrence and improving clinical outcomes.

慢性硬膜下血肿（CSDH）正变得越来越常见，尤其是在老年人群中，术后复发率达20%。钻孔引流术是标准治疗方法，但复发仍然是一个重大挑战。本研究评估了二次CSDH复发的发生率、处理方法以及文献和我们研究队列中各种血肿清除手术后的临床结局。再次手术目前是（后续）复发性CSDH的主要治疗方法，但会导致不良结局。鉴于高复发率和功能恢复不佳，需要有更好的治疗方法来解决CSDH的潜在病理生理问题。需要进一步研究来评估脑膜中动脉栓塞术在处理复发情况和改善临床结局方面的有效性。
