Objective The purpose of this study is to apply the method of CO-word analysis to the evidence-based study of the diagnosis and treatment of Budd-Chiari syndrome (BCS), to understand the trend of BCS research in China and to explore the hot spots of BCS in recent years, and to provide new evidence-based data for the clinical practice and experimental research of BCS in China.Methods In the Wanfang database, CNKI, and VIP retrieval platform, " Budd-Chiari syndrome” was used as the key word or title. According to the publication time, it was divided into before 1998 (study group 1), 1999–2008 (study group 2), and 2009–2018 years (study group 3). The relationship matrix was established by using the Netdraw tool in Ucinet6.0, and the common words were plotted with the Netdraw tool. The word relation network was used to get the analysis chart of the relation of the word.Results This study found that, Budd-Chiari syndrome, inferior vena cava, hepatic vein, inferior vena cava obstruction, and syndrome were the most frequently used keywords in the study group 1. Budd-Chiari syndrome, inferior vena cava, hepatic venous, interventional therapy, and patients were the most frequent keywords in the study group 2. In the study group 3, Budd-Chiari syndrome, interventional therapy, inferior vena cava, hepatic vein, and patient were the most frequent keywords.Conclusions Hepatic vein type and inferior vena cava type have became a research hotspot in recent years, and the thrombosis mechanism is one of the directions for domestic scholars to study the etiology of BCS. The diagnosis and classification of BCS depend on color doppler ultrasound technology. Many studies focus on the differential diagnosis of BCS and cirrhosis.
