Bibliometric Analysis of China’s Contribution to the Knowledge System of Cerebrovascular Intervention

Abstract

Abstract Background: Cerebrovascular disease has become the leading cause of death in China. The purpose of this article is to analyze China’s contribution to interventional treatment of cerebrovascular diseases. Methods: Bibliometric analysis was used for evaluating the quantity, quality, research hotspots, and cooperation network of publications from China. Articles were acquired from the database of Web of Science Core Collection. The authors, publication years, citation times, original regions, and source journals were recorded by EXCEL 2019. Network analysis and visualization were performed on Citespace5.6. Results: From 1991 to 2019, totally 5,052 articles regarding cerebrovascular intervention were published by Chinese researchers. The number of publications from China grew fastest annually in the latest five years among countries. These publications were totally cited 61,216 times, with 12.12 average citations per item. The h-index was 82. Affiliated hospitals of Capital Medical University contributed most articles. Cerebral ischemia and intracranial aneurysm were the most popular keywords over the three decades. The timeline view of keywords indicated that cerebral ischemia was always a hot spot. Stent techniques were the main treatment tools and still had a strong developing trend. Basic researches of cerebrovascular intervention had a preference for neural regeneration and neuroprotection. Conclusions: The number of publications from China grows fast in recent years, but research quality needs further enhancement. The highly targeted researches are continuously promoting the clinical practice of CVDs. More valuable clinical evidence would be provided.
