Abstract

Hydrocephalus is one of the most common complications of aneurysmal subarachnoid hemorrhage (aSAH), which seriously affects the quality of life and shortens the survival time of affected patients. By reviewing the recent studies on the risk factors of aSAH-associated hydrocephalus, we aimed to explicitly present the pathogenesis of acute and chronic hydrocephalus after aSAH and make a comprehensive list of the associated risk factors of aSAH-associated hydrocephalus and shunt-dependent hydrocephalus. It would help us to better explain the occurrence of hydrocephalus after aSAH, especially hydrocephalus caused by inflammation after bleeding. Many studies have recently suggested that high mobility group box 1 may be an early upstream promoter of inflammatory response after aSAH, which also provides important ideas for us to look for potential drug treatments. The surgery, such as external ventricular drain and lumbar drainage, is the most common and effective treatment. Yet, there are often complications, such as rebleeding and intracranial infection, and the optimal timing of intervention is controversial. Besides, this is also a systematic review of the recent advances in epidemiology, pathogenesis, diagnosis, and management of aSAH-associated hydrocephalus.

Journal Citation Reports/Science Edition Journal Citation Reports/Science Edition aims to evaluate a journal’s value from multiple perspectives including the journal impact factor, descriptive data about a journal’s open access content as well as contributing authors, and provide readers a transparent and publisher-neutral data & statistics information about the journal.

Chemical Abstracts Service Source Index The CAS Source Index (CASSI) Search Tool is an online resource that can quickly identify or confirm journal titles and abbreviations for publications indexed by CAS since 1907, including serial and non-serial scientific and technical publications.

IndexCopernicus The Index Copernicus International (ICI) Journals database’s is an international indexation database of scientific journals. It covered international scientific journals which divided into general information, contents of individual issues, detailed bibliography (references) sections for every publication, as well as full texts of publications in the form of attached files (optional). For now, there are more than 58,000 scientific journals registered at ICI.

Geneva Foundation for Medical Education and Research The Geneva Foundation for Medical Education and Research (GFMER) is a non-profit organization established in 2002 and it works in close collaboration with the World Health Organization (WHO). The overall objectives of the Foundation are to promote and develop health education and research programs.

Scopus: CiteScore 0.5(2019) Scopus is Elsevier's abstract and citation database launched in 2004. Scopus covers nearly 36,377 titles (22,794 active titles and 13,583 Inactive titles) from approximately 11,678 publishers, of which 34,346 are peer-reviewed journals in top-level subject fields: life sciences, social sciences, physical sciences and health sciences.
