This study aimed to analyze the global research trends and map the knowledge network of intracranial aneurysm (IA) research in the last 10 years.
Publications related to IA from 2012 to 2021 were retrieved from the Web of Science core collection. Microsoft Excel 2010 and VOSviewer were used to characterize the largest contributors, including authors, journals, institutions, and countries. CiteSpace and VOSviewer were adopted to analyze the trends and knowledge network of IA.
A total of 5,406 publications related to IA from 2012 to 2021 were identified, increasing from 344 in 2012 to 762 in 2021. Siddiqui, AH from the USA contributed the most publications. Papers published in the journal World Neurosurgery ranked first in quantity, while Stroke ranked first for total citations and citations per publication. The top three prolific institutions were Capital Medical University, Mayo Clinic, and the University Department of Neurology Utrecht from 2012 to 2021. Moreover, the USA held the greatest share in the field, and China was almost on par with the USA due to its rapid growth. Specifically, the most frequently covered topics over the recent decade were subarachnoid hemorrhage, endovascular treatment (EVT), clipping, vascular disorders, flow diverter, stent, delayed cerebral ischemia, inflammation, and hemodynamics.
The contribution made by different countries, institutions, journals, and authors for IA research over the past decade was demonstrated in the paper. The main topics include the choice of EVT or surgical clipping, particularly the application of flow diverter and associated complications, while themes such as the etiopathogenetic features of IA (e.g., inflammation and hemodynamics) deserve more attention.
本研究旨在分析过去10年颅内动脉瘤（IA）研究的全球趋势并绘制知识网络。
从科学网核心合集检索2012年至2021年与IA相关的出版物。使用Microsoft Excel 2010和VOSviewer来描述最大的贡献者，包括作者、期刊、机构和国家。采用CiteSpace和VOSviewer分析IA的趋势和知识网络。
共识别出2012年至2021年与IA相关的5406篇出版物，从2012年的344篇增加到2021年的762篇。美国的西迪基（AH Siddiqui）发表的出版物最多。发表在《世界神经外科杂志》上的论文数量排名第一，而《中风》在总被引次数和每篇出版物被引次数方面排名第一。2012年至2021年，多产的前三个机构是首都医科大学、梅奥诊所和乌得勒支大学神经科。此外，美国在该领域占比最大，中国由于快速发展几乎与美国相当。具体而言，近十年来最常涉及的主题是蛛网膜下腔出血、血管内治疗（EVT）、夹闭、血管疾病、血流导向装置、支架、迟发性脑缺血、炎症和血流动力学。
本文展示了过去十年不同国家、机构、期刊和作者对IA研究的贡献。主要主题包括EVT或手术夹闭的选择，特别是血流导向装置的应用及相关并发症，而IA的病因学特征（如炎症和血流动力学）等主题值得更多关注。
