Research Trends in Infected aortic aneurysms: Visualization and Bibliometric Analysis

Background: Infected aortic aneurysm is one of the most life-threatening cardiovascular diseases. There is still no standardized and uniform practice in the management of it. Objective: This study aimed to comprehensively analyze all the literatures related to infected aortic aneurysm in the past decades by using bibliometric tools from Web of Science Core Collection, revealing the research dynamics and hotspots in this field. Methods: We summarized the articles in the Web of Science Core Collection for infected aortic aneurysm in each year from January 2000 to October 2023. The bibliometric tools including SCImago, VOSviewer and CiteSpace were used to perform data extraction and visualization. The national characteristics of macro-geographical distribution, the contributions of disciplines, journals and authors, and cooperation network of institutions and authors were revealed. Results: A total of 1088 publications were included. The distribution of publications by year showed that the number of publications rose steadily since2004, followed by a decline from 2013 to 2017 and reaching a peak in 2021.The geographical distribution indicated that there was a large gap between the number of publications and citations in the United States and other countries.The co-authorship analysis showed that collaboration between prolific countries, productive institutions or excellent authors was scarce. The infected aortic aneurysm research was a multi-disciplinary field and most of the articles were published in journals related to surgery including Journal of Vascular Surgery, European Journal of Vascular and Endovascular Surgery etc. The keyword analysis revealed clustering and burst terms, indicating that current research focused on treatment of infected aortic aneurysm. Conclusions: This study revealed trends in research and public interest in infected aortic aneurysm. Our findings suggested that the field was growing, and the United States taking the lead position. Moreover, cooperation between countries should be strengthened, and future research hot spots might focus on deeper exploration of drug mechanisms, prediction of treatment efficacy, prediction of adverse events, and new modes of administration, such as combination therapy, which may pave the way for further research.
