Blunt cerebrovascular injuries (BCVI) remain a significant source of disability and mortality among trauma patients. The purpose of the present study was to determine whether knowledge silos exist in the overall BCVI literature.
An object-oriented programmatic script written in Python programming language was used to extract and categorize articles and references on the topic of BCVI. Additionally, each BCVI article was searched for by digital object identifier in the other BCVI references to build a network analysis and visualize topic reference patterns. Analyses were performed using Stata V.14.2 (StataCorp).
A total of 306 articles with 10 282 references were included for analysis. Of these, 24% (74) were published in neurosurgery journals, 45% (137) were published in trauma journals, and 31% (95) were published in a journal of another specialty. Similar proportions were found when categorized by author departmental affiliation. Trauma surgery authors disproportionately referenced articles in the trauma literature, compared with neurosurgeons (73.5% vs. 48.0%, p<0.0001), and other authors. The biggest factor influencing reference proportions was the specialty of the publishing journal. Finally, a network analysis revealed that there are more trauma BCVI articles, and there are more frequently cited trauma BCVI articles by all specialties.
This study revealed the existence of a one-way knowledge silo in the BCVI literature. However, a robust preference by both trauma and neurosurgery to cite trauma references when publishing in trauma journals may indicate a possible conscious curating of citations by authors to increase the likelihood of publication. These observations highlight the need for an active role by journal editors, peer reviewers, and authors to actively foster diversity of citations and cross-specialty collaboration to improve dissemination of information between these specialties.

钝性脑血管损伤（BCVI）仍是创伤患者致残和致死的重要原因。本研究的目的是确定在整个BCVI文献中是否存在知识孤岛现象。
使用用Python编程语言编写的面向对象的程序脚本提取和分类有关BCVI主题的文章及参考文献。此外，通过数字对象标识符在其他BCVI参考文献中搜索每篇BCVI文章，以构建网络分析并可视化主题引用模式。使用Stata V.14.2（StataCorp公司）进行分析。
共纳入306篇文章，包含10282条参考文献进行分析。其中，24%（74篇）发表于神经外科期刊，45%（137篇）发表于创伤期刊，31%（95篇）发表于其他专业期刊。按作者所属部门分类时也发现了类似比例。与神经外科医生（73.5%对48.0%，p<0.0001）及其他作者相比，创伤外科作者过多引用创伤文献中的文章。影响引用比例的最大因素是发表期刊的专业领域。最后，网络分析显示创伤BCVI文章更多，且所有专业引用创伤BCVI文章的频率更高。
本研究揭示了BCVI文献中存在单向知识孤岛现象。然而，创伤外科和神经外科在创伤期刊上发表文章时都强烈倾向于引用创伤参考文献，这可能表明作者有意识地精心挑选参考文献以增加发表可能性。这些观察结果凸显了期刊编辑、同行评审人员和作者积极发挥作用，以积极促进引用的多样性和跨专业合作，从而改善这些专业之间信息传播的必要性。
