Middle meningeal artery embolization for subdural hematoma: protocol for a systematic review and meta-analysis of randomized controlled trials

Abstract

Background: Middle meningeal artery embolization is an emerging neuroendovascular therapy for chronic subdural hematoma. Recently, a number of randomized control trials have been conducted to assess the efficacy of middle meningeal artery embolization to reduce the recurrence or progression of chronic subdural hematoma. Methods: A systematic review will be conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The authors will systematically search MEDLINE, EMBASE, Cochrane, and ClinicalTrials.gov (National Library of Medicine) for randomized control trials evaluating middle meningeal artery embolization for chronic subdural hematoma. A meta-analysis will be undertaken to compare patients undergoing middle meningeal artery embolization and standard care compared to standard care alone; primary effectiveness endpoints will be symptomatic recurrence, radiographic re-accumulation, or reoperation; secondary safety endpoints will be new disabling stroke, myocardial infarction, or death within 30 days. Discussion: This proposed systematic review and meta-analysis will synthesize and appraise available data regarding middle meningeal artery embolization, a novel neurointerventional therapy. Findings will help clinicians, patients, administrators, policy makers to determine the role of this new treatment and its potential benefits.

Author Declarations

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.

Yes
