Insights
Research on minimally invasive surgery (MIS) for intracerebral hemorrhage (ICH) is growing. Key areas include medication, devices, and surgical techniques for clot removal.
Area of Science:
- Neurosurgery
- Medical Technology
- Bibliometrics
Background:
- Intracerebral hemorrhage (ICH) presents significant morbidity and mortality risks.
- Minimally invasive surgery (MIS) for ICH shows potential for mortality reduction, but functional outcomes require further clarification.
- Bibliometric analysis offers insights into research trends and key areas within MIS for ICH.
Purpose of the Study:
- To conduct a bibliometric analysis of the scientific literature on minimally invasive surgery (MIS) for intracerebral hemorrhage (ICH).
- To identify publication trends, influential institutions, and emerging research themes in MIS for ICH from 2000 to 2021.
Main Methods:
- A comprehensive literature search was conducted in the Scopus database for articles published between 2000 and 2021.
- Primary research articles were included, while reviews and book chapters were excluded.
- Bibliometric analysis and visualization were performed using VOSviewer.
Main Results:
- A total of 278 articles were identified, with a notable increase in publications since 2008.
- Johns Hopkins University, University of Chicago, and Guiyang Medical College were leading institutions.
- Key research themes included medication-assisted clot removal, minimally invasive devices (e.g., endoscopes), craniotomy approaches, and clot lysis physiology.
Conclusions:
- The body of literature on minimally invasive surgery for ICH has expanded significantly since 2008.
- Emerging research focuses on thrombolysis, innovation in surgical devices, and optimizing surgical approaches for ICH evacuation.
Objective:
Intracerebral hemorrhage (ICH) is associated with significant morbidity and mortality. Randomized clinical trials focusing on minimally invasive surgery (MIS) for ICH evacuation have suggested a potential benefit regarding mortality but results remain unclear regarding impact on functional outcome. This study presents a bibliometric analysis investigating the current trends in the literature on MIS for ICH.
Methods:
Using the Scopus collection database, a search was performed to identify literature that discussed MIS for ICH from 2000 to 2021. Primary research articles were included in this study. Reviews and book chapters were excluded. Analysis and visualization of the included literature were completed with VOSviewer.
Results:
A total of 278 articles were identified. An upward trend in publications began in 2008, with the most publications in 2021 (36) followed by 2020 (25). The most citations occurred in 2013 (1192). The h-index, i-10 and i-100 were 37, 79 and 6 respectively. For the top 100 most cited studies, the mean citation count was 45.55 with a range of 6-760. The highest-producing institutions of MIS for ICH literature were Johns Hopkins University (31, 15 %), University of Chicago with (21, 10 %), Guiyang Medical College (17, 8 %), and Icahn School of Medicine at Mount Sinai (15, 7 %). Keyword analysis revealed four major avenues: 1) medication enhancement of clot removal, 2) minimally invasive devices such as endoscopes, 3) craniotomy approach, and 4) physiology of clot removal.
Conclusions:
The literature on MIS for ICH has been expanding since 2008. Key topics include thrombolysis, device innovation, and surgical approach.
