Abstract    Objective    To visualize and analyze contents and hotspots of abdominal aortic aneurysms in China.Methods    Using the China National Knowledge Infrastructure（CNKI）database as the source, 338 core articles were retrieved from 2010 to 2021, and the contents and hotspots were visually analyzed by CiteSpaceV software. Results    The overall trend of research publications in the field of abdominal aortic aneurysm in China in the past 10 years was smooth, and the research institutions were mainly affiliated hospitals of medical universities, and high-productive authors formed small groups relying on institutions, however cross-institutional or regional cooperation was less and not closely connected; endovascular aortic repair was the main research content, and in the past 3 years the research hotspots were endoleak( Strength: 2.24) and reintervention( Strength: 1.61) . Conclusion    The research trend was basically consistent with foreign studies，there was still a shortage of research in our country, which needs to be expanded, especially the inter-institutional cooperation.

Key words: abdominal aortic aneurysm, endovascular repair, endoleak, reintervention, visual analysis 

摘要： 目的    对国内腹主动脉瘤（AAA）研究热点与内容进行可视化分析。方法    以中国知网（CNKI）数据库为来源，检索国内2010—2021年核心文献共计338篇，通过CiteSpaceV软件对研究内容与热点进行可视化分析。结果    近10年来国内AAA领域研究发文量整体趋势平稳，研究机构主要为医学类高校附属医院，高产作者依托机构形成小团体，但跨机构或地区合作较少，联系不紧密；AAA腔内治疗（EVAR）为主要研究内容，近3年研究热点集中在内漏（Strength：2.24）与再干预（Strength：1.61）。结论    与国外相比研究趋势基本一致，国内研究仍有不足，需扩大涉及面，尤其是机构间合作。
