Research status of fetal hydrocephalus from 2003 to 2022 based on bibliometric analysis.

Hydrocephalus is the most common and devastating condition affecting the fetus. The aim of this study was to provide a comprehensive overview of the relevant literature through bibliometric analysis. The survey covers the articles related to congenital hydrocephalus published in the Web of Science Core Collection (WoSCC) database from January 1, 2003 to December 31, 2022. In addition to repeated literature, reviews and articles are included. We visualized the annual publication number, citation frequency, country/region, institution, author, periodical, and keywords with a range of software such as VOSviewer (1.6.18), Microsoft Excel 2019 (Redmond) and online analysis platform (https://bibliometric.com/ document). The results showed that the United States made the most important contribution to the research on fetal hydrocephalus. China's contribution has grown and developed strongly in recent years. The key words were mainly divided into four categories: basic research, epidemiology, treatment, and diagnostics. The number of publications related to fetal hydrocephalus has increased significantly, and it has a good development prospect in prenatal diagnosis and treatment.
