Bibliometric analyses are a well-established strategy for understanding the dynamics of publications. Aneurysmal subarachnoid hemorrhage (aSAH) is a hot topic in neurology and neurosurgery research. To perform a bibliometric analysis of recent publications within aSAH. Articles addressing aSAH published between 2017 and 2021 were included and had their information extracted from Scopus. A total of 2177 articles were included. The mean number of citations was 6.18 (95%CI = 5.77-6.59). 2021 and 2020 were the most prolific years. World Neurosurgery (N = 389/2,177 articles; 17,87%) was the leading publisher, and American Journal of Neuroradiology had the highest number of citations per article (14.82) among journals with ≥ 10 publications. Primary research (N = 1624/2177) predominated, followed by case reports (N = 434/2,177). Among secondary studies, systematic reviews (N = 78/119) surpassed narrative reviews (N = 41/119). USA led the number of publications (N = 548/2,177 articles; 25.17%), followed by China (N = 358/2,177 articles; 16.44%). High-income countries had a higher number of publications (N = 1624/2177) and more citations per article (6.84) than middle-income countries (N = 553/2177 and 4.25, respectively). There were zero articles from low-income countries. European and North American institutions had the greatest research impact. There was an increase in the number of published articles in the last few years (2020 and 2021). Many studies had a low level of evidence, whereas interventional studies were uncommon.
对出版物的动态进行文献计量分析是一种成熟的策略。蛛网膜下腔出血（aSAH）是神经病学和神经外科学研究的热门话题。对 aSAH 的近期出版物进行文献计量分析。纳入 2017 年至 2021 年间发表的关于 aSAH 的文章，并从 Scopus 中提取其信息。共纳入 2177 篇文章。平均引文数为 6.18（95%CI=5.77-6.59）。2021 年和 2020 年是发文量最多的年份。世界神经外科学（N=389/2177 篇文章；17.87%）是主要出版商，期刊中美国神经放射学杂志的单篇文章被引频次最高（14.82）≥10 篇。主要为原始研究（N=1624/2177），其次为病例报告（N=434/2177）。在二次研究中，系统评价（N=78/119）超过了叙述性综述（N=41/119）。美国发表的文章数量最多（N=548/2177 篇文章；25.17%），其次是中国（N=358/2177 篇文章；16.44%）。高收入国家的发文量（N=1624/2177 篇）和单篇文章被引频次（6.84）均高于中等收入国家（N=553/2177 篇和 4.25）。低收入国家没有文章。欧洲和北美机构的研究影响力最大。过去几年发表的文章数量有所增加（2020 年和 2021 年）。许多研究的证据水平较低，而介入性研究则较少。
