Red flags to screen for vertebral or carotid artery dissection in patients with neck pain or headache: a scoping review protocol

Background: Vertebral and carotid artery dissections may present as neck pain and/or headache in their early phases. Consequently, clinicians must screen for arterial dissections when assessing neck pain and/or headache patients. Considering that no secondary studies have been published on the red flags to screen for arterial dissections in patients with neck pain/headache, our scoping review will aim to gain a comprehensive understanding of the existing literature on patients with a carotid or vertebral artery dissection presenting with a primary complaint of neck pain and/or headache regarding the prevalence of associated signs and symptoms (e.g., neurological impairments and visual problems), the pain characteristics (e.g., intensity and localization), the demographic characteristics (e.g., gender and age), the prevalence of risk factors (e.g., cardiovascular), the mechanism of onset, and other relevant clinical predictors (e.g., comorbidities). Methods: We will search MEDLINE (via PubMed), Embase, CINHAL, and Scopus. In addition, we will use Web of Science to implement backward and forward citation tracking strategies. We will include any primary study design (e.g., case control studies, case reports and case series, and cohort studies) written in English, Dutch, or Italian without any time restriction. To be included, studied had to focus on adult patients (> 18 years of age) of any gender with a diagnosis of vertebral or artery dissection and with a primary complaint of neck pain and/or headache, with a reporting on other signs/symptoms, pain characteristics, demographic information, risk factors, or onset mechanisms. Two authors will independently perform the study selection and data extraction phases. Results from the scoping review will be summarized descriptively through tables and diagrams. As a scoping review, we will highlight any gaps in the existing literature regarding our research questions. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement This study did not receive any funding. ### 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 All data produced in the present study will be available upon reasonable request to the authors.
