Key result
Bibliometric analysis shows TBAD research shifting from surgical methods to clinical management and post-TEVAR prognosis.
Why the study?
This study aimed to reveal the development process and transitions of research hotspots in type B aortic dissection over the past 20 years using bibliometric research.
Bibliometric analysis reveals that research on type B aortic dissection has shifted from surgical method selection to clinical management, patient prognosis after TEVAR, and aortic remodeling.
This study aimed to analyze and visualize the research on type B aortic dissection (TBAD) over the past 20 years through bibliometric research. To reveal the development process of TBAD research and the transitions of research hotspots. Literatures was retrieved from the Web of Science Core Collection. The analysis utilized tools such as Microsoft Office Excel, VOSviewer and CiteSpace for bibliometric mapping and visualization, including assessing publication volumes and constructing collaborative networks and keyword burst graphs. A total of 1391 related articles or reviews on TBAD were included. The number of annual publications is steadily increasing. China was the top country in terms of the number of publications. University of Michigan (n = 60) was the most productive university. The Journal of Vascular Surgery (n = 183) was the most published and co-cited journal. Keywords burst analysis showed that "guidelines", "spinal-cord ischemia", "society", "impact", and "aortic remodeling" were the most frequently used keywords in recent years. In general, the research focus of TBAD has gradually changed from selecting the surgical method to the best clinical management and patient prognosis after thoracic endovascular aortic repair (TEVAR). Promoting positive aortic remodeling and aortic hemodynamics may be the research hotspots in the future.

Zhao et al. (2025) studied Type B aortic dissection (n=1,391). Bibliometric analysis was evaluated on Research hotspots and development process of TBAD research. Bibliometric analysis of 1,391 articles on type B aortic dissection from 2004-2023 revealed a shift in research focus from surgical methods to clinical management and post-TEVAR prognosis.
