Contemporary clinical applications of venous excess ultrasound: A scoping review protocol

Following PRISMA-ScR guidelines, this scoping review will conduct systematic searches of both peer-reviewed and grey literature sources, including PubMed, Scopus, the Cochrane Library, ProQuest, Google Scholar, preprint servers, and clinical trial registries. Where literature sources allow, searches will be limited to studies written in English and published from 1 January 2020 onward. References will be managed and deduplicated using Zotero. Full-text screening and data extraction will be performed independently by two reviewers using Rayyan and standardised Microsoft Excel forms. Disagreements will be resolved through discussion or, if necessary, by a third reviewer. Results will be summarised in tables and narratively.
