Since its recognition as an independent surgical subspecialty, vascular surgery has experienced rapid growth in both surgical volume and research productivity. Trends in vascular surgery research have not been well characterized. Understanding how research in the field has evolved in comparison to interventional radiology can offer insights into evolving interests and discrepancies between the specialties.
Primary and secondary research publications indexed in the MEDLINE database from 1992 to 2023 were analyzed using a novel text mining algorithm. Eight high-impact vascular surgery journals and 6 interventional radiology journals were included. Articles were categorized based on treatment modalities, pathologies, and other subgroup analyses. Temporal trends were assessed using linear regression and correlation analysis. A comparative analysis was performed assessing publication trends by broad pathology groups between vascular surgery and interventional radiology journals. A further subgroup analysis was conducted comparing publication trends by endovascular treatment modality for peripheral arterial disease (PAD).
28,931 vascular surgery publications and 13,094 interventional radiology publications met the inclusion criteria. Publication volume grew exponentially, with over 50% emerging in the last decade. Publications exploring endovascular interventions have increasingly exceeded those focused on exclusively open interventions in research volume since 2006. Aortic pathology, carotid disease, PAD, and venous pathology represented the vast majority of vascular surgery research output, with PAD exhibiting the fastest growth. Comparative analysis revealed a number of key differences in research focus and treatment modalities between vascular surgery and interventional radiology, including a greater emphasis on venous pathology in interventional radiology journals and fewer relative publications on carotid artery pathology (P < 0.001). When comparing endovascular treatments for PAD, interventional radiology journals published more frequently on endovascular brachytherapy (8.73% vs 1.02%, P < 0.001) and less frequently on atherectomy (4.29% vs 6.50%, P = 0.035) as compared to the vascular surgery journals.
Our findings demonstrate increasing emphasis on endovascular interventions and specific pathologies in vascular surgery research. Despite some key differences, there is notable overlap in interests between vascular surgery and interventional radiology, which may represent promising opportunities for collaboration in advancing endovascular procedures. Differences in research focus may stem from specialty perspectives and be perpetuated by differences in training.
自血管外科被确认为一个独立的外科亚专业以来，其手术量和研究产出均迅速增长。血管外科研究的趋势尚未得到充分描述。了解该领域的研究与介入放射学相比是如何发展的，有助于洞察各专业不断变化的兴趣点和差异。
使用一种新颖的文本挖掘算法，对1992年至2023年MEDLINE数据库中索引的一级和二级研究出版物进行分析。纳入了8种高影响力的血管外科期刊和6种介入放射学期刊。文章根据治疗方式、病理学和其他亚组分析进行分类。使用线性回归和相关分析评估时间趋势。进行了一项比较分析，评估血管外科和介入放射学期刊之间按广泛病理学组划分的出版趋势。还进行了进一步的亚组分析，比较外周动脉疾病（PAD）的血管内治疗方式的出版趋势。
28931篇血管外科出版物和13094篇介入放射学出版物符合纳入标准。出版物数量呈指数增长，超过50%的出版物出现在过去十年。自2006年以来，探索血管内干预的出版物在研究数量上越来越超过专注于单纯开放手术的出版物。主动脉病理学、颈动脉疾病、PAD和静脉病理学占血管外科研究产出的绝大部分，其中PAD增长最快。比较分析揭示了血管外科和介入放射学在研究重点和治疗方式上的一些关键差异，包括介入放射学期刊对静脉病理学的重视程度更高，而关于颈动脉病理学的相对出版物较少（P < 0.001）。在比较PAD的血管内治疗时，与血管外科期刊相比，介入放射学期刊关于血管内近距离放射治疗的发表频率更高（8.73%对1.02%，P < 0.001），而关于旋切术的发表频率更低（4.29%对6.50%，P = 0.035）。
我们的研究结果表明，血管外科研究越来越重视血管内干预和特定病理学。尽管存在一些关键差异，但血管外科和介入放射学在兴趣方面有显著重叠，这可能代表了在推进血管内手术方面合作的有前景的机会。研究重点的差异可能源于专业视角，并因培训差异而持续存在。
