Efficacy of microsurgery for dural arteriovenous fistula: A systematic review protocol.

Abstract

Background:Microsurgery is a treatment option for dural arteriovenous fistula (DAF), but its efficacy is still unclear. This study aims to assess the efficacy and safety of microsurgery for the treatment of patients with DAF.Methods:We will carry out this study assessing the use of microsurgery in patients with DAF from the following electronic databases: PUBMED, EMBASE, Cochrane Library, CINAHL, PsycINFO, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure. All those databases will be searched from inception to the present without language limitations. Two independent authors will perform study selection, data extraction, and methodological quality assessment. RevMan 5.3 Software will be applied for statistical analysis.Results:This study will assess the efficacy and safety of microsurgery for the treatment of patients with DAF through measuring initial treatment failure, late recurrence, neurological improvement, quality of life, and complications.Conclusion:This study will provide most recent evidence of microsurgery for the treatment of patients with DAF.Dissemination and ethics:The findings of this systematic review will be published in peer-reviewed journals. This systematic review dose not needs ethic approval, because it just analyzes the published data without individual information involvement.Systematic review registration:PROSPERO CRD42019144851.
