Due to the significant increase in cesarean section rates worldwide, cesarean scar pregnancy (CSP) has attracted extensive attention. This study aimed to investigate the global research status and developmental directions of CSP to discern promising research hotspots by means of bibliometrics and visualized analyses.
The English CSP-related literature from 2001 to 2020 was retrieved from The Web of Science Core Collection (WOSCC) database. Microsoft Excel 2019 was used to analyze the years, countries, institutions, journals, authors, citations, H indices, titles, abstracts, and keywords of related literature, and VOSviewer software was used to visualize developmental directions and promising hotspots in CSP.
The study included 1,186 articles in total. The number of CSP articles has presented an overall increasing trend over the last two decades. China has the maximum number of publications, but America's H-index is higher than that of China, with the average number of citations per item ranking fourth. The Journal of Obstetrics and Gynaecology Research published the most on the subject, while Zhejiang University from China published the largest number of articles; Jurkovic D, Timor-Tritsch IE, and Monteagudo A have achieved considerable progress in the CSP domain. There are 5 clusters that the current research orientation can fall into: "selection of the delivery mode with a scarred uterus after cesarean section", "risk factors", "diagnosis", "treatment" and "related basic and clinical experiments". High-intensity focused ultrasound (HIFU) and the formulation of consensus guidelines are the focus of the current research.
The analysis of global trends shows that CSP research is being actively studied and that the number of published studies is continuously increasing. According to the comprehensive quality and quantity of the literature, the United States maintains a leading position in CSP research. In recent years, the research directions have mainly focused on "diagnosis", "treatment" and "risk factors", while HIFU and the formulation of consensus guidelines may become research hotspots in the field of CSP.
由于全球剖宫产率的显著增加，剖宫产瘢痕妊娠（CSP）引起了广泛关注。本研究旨在通过文献计量学和可视化分析，探讨 CSP 的全球研究现状和发展方向，以识别有前途的研究热点。
从 Web of Science 核心合集（WOSCC）数据库中检索 2001 年至 2020 年发表的英文 CSP 相关文献。使用 Microsoft Excel 2019 分析相关文献的年份、国家、机构、期刊、作者、引用、H 指数、标题、摘要和关键词，并使用 VOSviewer 软件可视化 CSP 的发展方向和有前途的热点。
本研究共纳入 1186 篇文章。过去 20 年，CSP 文章数量呈现总体上升趋势。中国发表的文章数量最多，但美国的 H 指数高于中国，篇均被引频次排名第四。《妇产科学研究杂志》发表的文章最多，而中国的浙江大学发表的文章最多；Jurkovic D、Timor-Tritsch IE 和 Monteagudo A 在 CSP 领域取得了相当大的进展。当前研究方向可以分为 5 个聚类：“剖宫产术后子宫瘢痕的分娩方式选择”、“危险因素”、“诊断”、“治疗”和“相关基础和临床实验”。高强度聚焦超声（HIFU）和共识指南的制定是当前研究的重点。
全球趋势分析表明，CSP 研究正在积极开展，发表的研究数量不断增加。根据文献的综合质量和数量，美国在 CSP 研究中保持领先地位。近年来，研究方向主要集中在“诊断”、“治疗”和“危险因素”，而 HIFU 和共识指南的制定可能成为 CSP 领域的研究热点。
