OBJECTIVE: The aim of this study is to evaluate the 100 most highly cited articles assessing posterior communicating artery aneurysms. METHODS: In May 2024, a comprehensive search was conducted in the Scopus database using the keyword "posterior communicating artery aneurysm" The top-100 most impactful articles were ranked by citation count and analyzed for relevant factors. Citations per year were calculated to minimize the risk of bias. Google Scholar (GS) and Web of Science (WOS) citations were also included. RESULTS: The top-100 articles were published between 1978 and 2022, with a total of 2935 citations in Scopus, 3988 in GS, and 2508 in WOS. The mean number of citations was 29.4 (range 12-158) on Scopus, 40.7 (range 10-216) on GS, and 26.9 (range 9-120) on WOS. The most contributing country was the United States, while the leading institution was the Second Military Medical University in China. The most productive journal was World Neurosurgery, producing 15 articles. The most prolific author was Liu J.-M with 10 published articles. The funding body with the most funded publication was the National Natural Science Foundation of China. Subcategory analysis revealed that the majority of articles focused on treatment options and postsurgical outcomes, oculomotor nerve palsy, and clinical features. CONCLUSIONS: This study offers a detailed overview of the most cited articles on posterior communicating artery aneurysms. It demonstrates key contributions made by different countries, institutions, journals, and authors, providing a valuable framework for understanding the evidence supporting the management of these aneurysms.
