BackgroundAs a common hemorrhagic cerebrovascular disease, subarachnoid hemorrhage (SAH) has high mortality and disability. Delayed cerebral ischemia (DCI) is among the major complications after SAH, severely affecting the patient prognosis. Through bibliometric analysis, this study investigated the global research status, trends, and hotspots of DCI after SAH from 2013 to 2022, providing a scientific reference for researchers in this field.MethodsWe searched the Web of Science Core Collection for articles and associated records from 2013 to 2022. The data were analyzed and presented using VOSviewer software.ResultsThis study covered 3436 articles, and the number of publications issued by DCI after SAH study increased annually. The United States published the most papers and had the highest number of citations. Harvard University and World Neurosurgery were the institutions and journals with the most published papers. Keyword analysis indicated that the recent research on DCI after SAH has focused on its pathophysiological mechanisms.ConclusionsDCI after SAH has drawn increasing interest in academic circles during the past decade. This study presented an objective, systematic, and comprehensive analysis of the literature on DCI after SAH. Currently, the hotspots in this field focus on pathophysiological mechanisms.Copyright © 2023 Elsevier Inc. All rights reserved.
