动脉瘤性蛛网膜下腔出血研究的文献计量学分析

Bibliometric analysis of research on aneurysmal subarachnoid hemorrhage

目的对2012至2022年期间全球有关动脉瘤性蛛网膜下腔出血(aneurysmal subarachnoid hemorrhage,aSAH)研究的科学出版物进行文献计量学分析,探讨该领域的研究现状和热点。方法以Web of Science Core Collection为数据源。按照设定的检索策略,采用CiteSpace文献计量学工具,对已发表文献进行分析,探索研究热点和前沿方向。结果共纳入4937篇文献,发文量从2012年到2022年逐年增加。美国是该领域的领先国家,哈佛大学是该领域的领先机构,Rinkel Gabriel JE是该领域发表文章最多的研究者。对作者提供的关键词进行的分析显示,迟发性脑缺血、血管痉挛、风险、颅内动脉瘤、血管内治疗、危险因素、栓塞、并发症、Pipeline栓塞装置、弹簧圈栓塞、血流动力学、壁面剪应力是aSAH研究的主要热点和前沿方向。结论文献计量学分析结果有助于掌握aSAH的研究现状,确定未来研究的新方向。

Objective To conduct a bibliometric analysis of scientific publications on aneurysmal subarachnoid hemorrhage(aSAH)worldwide from 2012 to 2022 and to investigate the current research status and hotspots in this field.Methods The Web of Science Core Collection was used as the data source.According to the set retrieval strategy,the CiteSpace bibliometric tools were used to analyze the published literature and explore the research hotspots and cutting-edge directions.Results A total of 4937 articles were included,and the number of publications increased year by year from 2012 to 2022.The United States is a leading country in this field,Harvard University is a leading institution in this field,and Rinkel Gabriel JE is the researcher with the most published articles in this field.The analysis of the keywords provided by the author showed that delayed cerebral ischemia,vasospasm,risk,intracranial aneurysms,endovascular treatment,risk factors,embolization,complications,Pipeline embolization device,coil embolization,hemodynamics,and wall shear stress were the main hotspots and cutting-edge directions of aSAH research.Conclusion The results of bibliometric analysis help to grasp the current research status of aSAH and determine new directions for future research.
