ObjectiveWe performed a bibliometric analysis of studies reporting cases of brain and spinal arteriovenous malformations (AVMs).MethodsWe retrieved the 100 most cited reports in brain and spinal AVM research from Scopus and assessed the citation count, journal of publication and its impact factor, year of publication, first author and corresponding authors and their h-index, country, institution, department, and study category.ResultsThe median number of citations per article was 215. The Journal of Neurosurgery was the most prolific journal (39 reports and 12,069 citations), including 9 of the 10 most cited reports. Seventy reports (19,251 citations), including 8 of the 10 most cited, were from the United States. The Barrow Neurological Institute was the most cited institution (7 reports; 2792 citations), and the Mayo Clinic had the greatest number of reports (8 reports; 1994 citations). Most studies had been reported before 2000 (71 reports; 19,262 citations). The most discussed topics were treatment (40 studies; 9560 citations) and natural history and/or clinical features (37 studies; 9595 citations). Neurosurgery was the most prolific department (58 studies; 15,860 citations). Spetzler was the author with the highest number of articles (n = 7) and citations (n = 2792).ConclusionsBrain and spinal AVM research was centralized in the United States, has been mainly reported in specific neurosurgical journals, and has been more often related to treatment and natural history and/or clinical features. It is possible that high impact AVM research has been decreasing recently. Because the best approach to these pathological entities remains controversial, research stimulation within this field should be encouraged.Copyright © 2019 Elsevier Inc. All rights reserved.
