An emerging web: A half-century bibliometric analysis of carotid web literature

Objective: Carotid webs, first described in 1968, are increasingly recognized as a surgically treatable cause of ischemic stroke, particularly in young patients. Despite growing attention, the literature remains fragmented. We conducted the first advanced bibliometric analysis of carotid web research to map its historical foundations, identify key contributors, and illustrate emerging trends. Methods: The Web of Science database (inception-2025) was queried for carotid web publications. Articles and metadata were analyzed using Bibliometrix (R) and Python libraries. Reference publication year spectroscopy (RPYS) was employed to analyze the field's roots by analyzing citation frequency by publication year. Results: A total of 281 publications from 109 sources and 1,129 authors were identified. Annual publication growth averaged 6.15%, with 90% published after 2016. International collaboration was modest (9-11%), led by the U.S., China, France, and Canada. Shifts in keyword frequency reflected the field's evolution from early nosological uncertainty toward recognition of carotid webs as a distinct, high-risk lesion underlying ischemic stroke. Stroke and Journal of Vascular Surgery emerged as early key sources. Author analysis identified the most prolific contributors, though coauthorship networks remained small. RPYS revealed 19 seminal studies (1968-2021) that shaped the field's progression from early pathology descriptions to recognition of carotid webs as high-risk lesions for stroke. Conclusions: Carotid web research has rapidly expanded, evolving into a multidisciplinary field. RPYS identified 19 seminal publications tracing the intellectual trajectory of the field. Ongoing challenges include limited collaboration, unresolved questions of pathogenesis, and variability in terminology and diagnostic criteria.
