Abstract
Background and Aim: Spontaneous intracranial hypotension (SIH) is a highly misdiagnosed disease. The main reason is the lack of awareness. This study sought to summarize the current status of research in this field via a bibliometric analysis. Materials and Methods: The publications were searched in the Web of Science Core Collection (WoSCC) database. Data analysis and visualization were carried out using the cooperative network and cluster analysis of R and Cite Space software. Results: A total of 618 publications from 2008 to 2021 were included in this study. The number of publications has a growth trend. The United States contributed the most articles, and Schievink WI is the most prolific author. Mayo Clinical ranked the first compared with other institutions. American Journal of Neuroradiology has published the most articles in this field. The top 3 clusters of reference co-citation are “delayed recurrence”, “cerebrospinal fluid-venous fistula”, and “floating dural sac sign”. The top 3 clusters of keyword co-appearance are “spinal fluid leak headache”, “symptom duration”, and “cerebral venous thrombosis”. The strongest citation burst of keywords is “CSF-venous fistula” and “paraspinal vein sign”. Conclusions: This study analyzes the research progress of SIH, and the current research mainly focuses on CSF-venous fistula. The bibliometric analysis of SIH is expected to help researchers effectively explore the disease.
