Ethics in publishing
Please see our information pages on Ethics in publishing and Ethical guidelines for journal publication.
Work on human beings that is submitted to European Journal of Vascular and Endovascular Surgery should comply with the principles laid down in the Declaration of Helsinki (Recommendations guiding physicians in biomedical research involving human subjects. Adopted by the 18th World Medical Assembly, Helsinki, Finland, June 1964, amended by the 29th World Medical Assembly, Tokyo, Japan, October 1975, the 35th World Medical Assembly, Venice, Italy, October 1983, and the 41st World Medical Assembly, Hong Kong, September 1989). The manuscript should contain a statement that the work has been approved by the appropriate ethical committees related to the institution(s) in which it was performed and that subjects gave informed consent to the work. Studies involving experiments with animals must state that their care was in accordance with institution guidelines. Patients (and volunteers) names, initials, and hospital numbers should not be used.
All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. Authors must disclose any interests in two places: 1. A summary declaration of interest statement in the title page file (if double-blind) or the manuscript file (if single-blind). If there are no interests to declare then please state this: 'Declarations of interest: none'. This summary statement will be ultimately published if the article is accepted. 2. Detailed disclosures as part of a separate Declaration of Interest form, which forms part of the journal's official records. It is important for potential interests to be declared in both places and that the information matches. More information.
Conflict of interest statement
At the end of the text, under a subheading 'Conflict of interest statement', all authors must disclose any financial and personal relationships with other people or organisations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding.
If you have published similar work before, then please tell us and send us copies of previous publications so that we may assess the degree of overlap.
Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint, see 'Multiple, redundant or concurrent publication' section of our ethics policy for more information), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder. To verify originality, your article may be checked by the originality detection service Crossref Similarity Check.
All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted.
All contributors who do not meet the criteria for authorship as defined above should be listed in an acknowledgements section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chair who provided only general support. Authors should disclose whether they had any writing assistance and identify the entity that paid for this assistance. Reporting clinical trials (CONSORT)
All randomised controlled trials submitted for publication in the European Journal of Vascular and Endovascular Surgery should include a completed Consolidated Standards of Reporting Trials (CONSORT) flow chart. Please refer to the CONSORT statement website at http://www.consort-statement.org for more information. European Journal of Vascular and Endovascular Surgery has adopted the proposal from the ICMJE which require, as a condition of consideration for publication of clinical trials, registration in a public trials registry. Trials must register at or before the onset of patient enrolment. The clinical trial registration number (ISRCTN) should be included at the end of the abstract of the article. For this purpose, a clinical trial is defined as any research project that prospectively assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome. Studies designed for other purposes, such as to study pharmacokinetics or major toxicity (e.g. phase I trials) would be exempt. Further information can be found at http://www.icmje.org
The Editors of the EJVES are keen to help authors write their manuscripts in a manner that is likely to make them more scientifically robust. To that end, we have prepared guidance on how to prepare a manuscript which involves; (1) randomised trials, (2) systematic reviews and meta-analyses, (3) observational studies and (4) studies involving animals. Guidance for the preparation of these papers can be found here.
Systematic reviews and meta-analyses
Systematic reviews and meta-analyses of randomized controlled trials of studies that evaluate health care interventions and of observational studies submitted to the European Journal of Vascular and Endovascular Surgery must follow the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. See http://www.prisma-statement.org or BMJ 2009;339:b2535. Reports should include a flow diagram of study inclusion and exclusion and the abstract headings (Objectives, Data Sources, Review Methods, Results, Conclusions) as described in the PRISMA guidelines.Systematic reviews and meta-analyses of diagnostic research should include a methodological assessment, guided by e.g. the QUADAS-2 tool, an instrument specifically developed for quality assessment of diagnostic accuracy studies. Ann Intern Med 2011;155:29-36.
We subscribe to the `Uniform Requirements for Manuscripts Submitted to Biomedical Journals, published by the International Committee of Medical Journal Editors, available from http://www.icmje.org.

Language (usage and editing services)
Please write your text in good English (American or British usage is accepted, but not a mixture of these). Authors who feel their English language manuscript may require editing to eliminate possible grammatical or spelling errors and to conform to correct scientific English may wish to use the English Language Editing service available from Elsevier's WebShop.
Our online submission system guides you stepwise through the process of entering your article details and uploading your files. The system converts your article files to a single PDF file used in the peer-review process. Editable files (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the Editor's decision and requests for revision, is sent by e-mail.
Submit your article
Please submit your article via http://www.ees.elsevier.com/ejves/.
This journal operates a single blind review process. All contributions are typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. The Editor's decision is final. More information on types of peer review.
It is important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier). Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also the section on Electronic artwork.
To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor. Length
Articles should be as brief as possible, a maximum of 4000 words including references, and we will shorten lengthy manuscripts. The discussion should be clear, concise, and limited to matters arising directly from the results. Papers should include a maximum of 7 figures/illustrated images/tables.
Each of the following sections should begin on a new page, with all pages numbered serially:
•Abstract and 3-6 key words
•Main text in the format of Introduction, Materials and Methods, Results and Discussion
•Legends for illustrations.
Put the text, references, tables and legends for figures in one file, and each figure in a separate file.Word count
Please indicate the word count on the front page of your manuscript.
Subdivision - unnumbered sections
Divide your article into clearly defined sections. Each subsection is given a brief heading. Each heading should appear on its own separate line. Subsections should be used as much as possible when cross-referencing text: refer to the subsection by heading as opposed to simply 'the text'.
Use the standard format (Introduction, Materials and Methods, Results, Discussion).<\p>
Please provide a brief statement (maximum 100 words) to answer the question "What does this study/review add to the existing literature and how will it influence future clinical practice". At the discretion of the editors, this statement may be placed at the beginning of the published article.
Essential title page information
• Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
• Author names and affiliations. Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. You can add your name between parentheses in your own script behind the English transliteration. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
• Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.
• Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
The title page should additionally include:
•The category for which the manuscript is being submitted (original article, leading article, review, case report, technique, or lesson of the month).
•A short title of not more than 50 characters (running head).
The abstract should not exceed 300 words and should conform to the following format:
Although a graphical abstract is optional, its use is encouraged as it draws more attention to the online article. The graphical abstract should summarize the contents of the article in a concise, pictorial form designed to capture the attention of a wide readership. Graphical abstracts should be submitted as a separate file in the online submission system. Image size: Please provide an image with a minimum of 531 × 1328 pixels (h × w) or proportionally more. The image should be readable at a size of 5 × 13 cm using a regular screen resolution of 96 dpi. Preferred file types: TIFF, EPS, PDF or MS Office files. You can view Example Graphical Abstracts on our information site.
Authors can make use of Elsevier's Illustration Services to ensure the best presentation of their images and in accordance with all technical requirements.
Three to six keywords or short phrases that will assist indexers in cross-referencing the article should be included. Terms from the medical subject headings (MeSH) list of Index Medicus should be used (see http://www.ncbi.nlm.nih.gov).
Authors should limit the use of abbreviations. Terms which are mentioned frequently may be abbreviated but only if this does not detract from reader comprehension. Abbreviations for SI units and statistical terms are those in Baron DN (ed): Units, Symbols and Abbreviations: A Guide for Biological and Medical Editors and Authors 4th ed. London, Royal Society of Medicine, 1994.
Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).
The acknowledgements page should specify:
•Contributions that need acknowledging but do not justify authorship, e.g. technical help
•Sources of financial and material support.
List funding sources in this standard way to facilitate compliance to funder's requirements:
Funding: This work was supported by the National Institutes of Health [grant numbers xxxx, yyyy]; the Bill & Melinda Gates Foundation, Seattle, WA [grant number zzzz]; and the United States Institutes of Peace [grant number aaaa].It is not necessary to include detailed descriptions on the program or type of grants and awards. When funding is from a block grant or other resources available to a university, college, or other research institution, submit the name of the institute or organization that provided the funding.
If no funding has been provided for the research, please include the following sentence:This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
Tables should be kept as simple as possible and wherever possible a graphical presentation used instead.guidelines, where a relevant guideline exists.
Increased discoverability of research and high quality peer review are ensured by online links to the sources cited. In order to allow us to create links to abstracting and indexing services, such as Scopus, CrossRef and PubMed, please ensure that data provided in the references are correct. Please note that incorrect surnames, journal/book titles, publication year and pagination may prevent link creation. When copying references, please be careful as they may already contain errors. Use of the DOI is encouraged.
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.
This journal encourages you to cite underlying or relevant datasets in your manuscript by citing them in your text and including a data reference in your Reference List. Data references should include the following elements: author name(s), dataset title, data repository, version (where available), year, and global persistent identifier. Add [dataset] immediately before the reference so we can properly identify it as a data reference. The [dataset] identifier will not appear in your published article.
Reference management software
Most Elsevier journals have their reference template available in many of the most popular reference management software products. These include all products that support Citation Style Language styles, such as Mendeley and Zotero, as well as EndNote. Using the word processor plug-ins from these products, authors only need to select the appropriate journal template when preparing their article, after which citations and bibliographies will be automatically formatted in the journal's style. If no template is yet available for this journal, please follow the format of the sample references and citations as shown in this Guide.
Users of Mendeley Desktop can easily install the reference style for this journal by clicking the following link:
When preparing your manuscript, you will then be able to select this style using the Mendeley plug-ins for Microsoft Word or LibreOffice.
References should be typed with double spacing and cited in the Vancouver style. Unpublished communications should be cited in the text, in parentheses.
In the text, references should be numbered consecutively by superscript: 1,2 or 1-3. References should be listed in numerical order at the end of the article. The sequence for a journal article is: author(s), title of paper, journal name (abbreviated as in Index Medicus or written in full if no abbreviation quoted), year of publication, volume number, first and last pages. If there are more than six authors list only the first six followed by 'et al.' Journal titles should be abbreviated according to Index Medicus (see http://www.nlm.nih.gov/tsd/serials/lji.html). The sequence for a book is: author(s), editor(s) or compiler(s), title and edition number, place of publication and publisher's name, year of publication, first and last pages (if relevant).Examples:

Journal names should be abbreviated according to the List of Title Word Abbreviations.
Authors of original articles and reviews undergoing revision after initial peer review for publication in the European Journal of Vascular and Endovascular Surgery will be asked to provide two MCQ questions relating to their article. Authors should write MCQ questions referring to "How to write a high quality multiple choice question (MCQ): a guide for clinicians", Coughlin PA, Featherstone CR, European Journal of Vascular and Endovascular Surgery 2017;54: 654-658, https://doi.org/10.1016/j.ejvs.2017.07.012.
Supplementary material such as applications, images and sound clips, can be published with your article to enhance it. Submitted supplementary items are published exactly as they are received (Excel or PowerPoint files will appear as such online). Please submit your material together with the article and supply a concise, descriptive caption for each supplementary file. If you wish to make changes to supplementary material during any stage of the process, please make sure to provide an updated file. Do not annotate any corrections on a previous version. Please switch off the 'Track Changes' option in Microsoft Office files as these will appear in the published version.
This journal encourages and enables you to share data that supports your research publication where appropriate, and enables you to interlink the data with your published articles. Research data refers to the results of observations or experimentation that validate research findings. To facilitate reproducibility and data reuse, this journal also encourages you to share your software, code, models, algorithms, protocols, methods and other useful materials related to the project.
Below are a number of ways in which you can associate data with your article or make a statement about the availability of your data when submitting your manuscript. If you are sharing data in one of these ways, you are encouraged to cite the data in your manuscript and reference list. Please refer to the "References" section for more information about data citation. For more information on depositing, sharing and using research data and other relevant research materials, visit the research data page.Data linking
If you have made your research data available in a data repository, you can link your article directly to the dataset. Elsevier collaborates with a number of repositories to link articles on ScienceDirect with relevant repositories, giving readers access to underlying data that gives them a better understanding of the research described.
There are different ways to link your datasets to your article. When available, you can directly link your dataset to your article by providing the relevant information in the submission system. For more information, visit the database linking page.For supported data repositories a repository banner will automatically appear next to your published article on ScienceDirect.
In addition, you can link to relevant data or entities through identifiers within the text of your manuscript, using the following format: Database: xxxx (e.g., TAIR: AT1G01020; CCDC: 734053; PDB: 1XFN).Mendeley Data
This journal supports Mendeley Data, enabling you to deposit any research data (including raw and processed data, video, code, software, algorithms, protocols, and methods) associated with your manuscript in a free-to-use, open access repository. Before submitting your article, you can deposit the relevant datasets to Mendeley Data. Please include the DOI of the deposited dataset(s) in your main manuscript file. The datasets will be listed and directly accessible to readers next to your published article online.
For more information, visit the Mendeley Data for journals page.Data statement
To foster transparency, we encourage you to state the availability of your data in your submission. This may be a requirement of your funding body or institution. If your data is unavailable to access or unsuitable to post, you will have the opportunity to indicate why during the submission process, for example by stating that the research data is confidential. The statement will appear with your published article on ScienceDirect. For more information, visit the Data Statement page.
The journal encourages authors to create an AudioSlides presentation with their published article. AudioSlides are brief, webinar-style presentations that are shown next to the online article on ScienceDirect. This gives authors the opportunity to summarize their research in their own words and to help readers understand what the paper is about. More information and examples are available. Authors of this journal will automatically receive an invitation e-mail to create an AudioSlides presentation after acceptance of their paper.
Authors should set out clearly the objectives of the study and state whether the study was retrospective or prospective. Randomised trials must include the items included in the CONSORT statement (see 'Randomised Controlled Trials', above).
Wherever possible a graphical presentation should be used to illustrate the main findings of a study. Base the graph on data points unless the sample sizes are very large. When plotting life tables always indicate the numbers of individuals at risk at the various times of follow-up. Avoid the use of 'error bars' showing 1 standard deviation or standard error.
The use of a mean and standard deviation (SD) to describe a distribution is only appropriate when the distribution is known to be normal. For non-parametric data, the median is a better measure of the centre of the distribution and the range or interquartile range (IQR), a better measure of spread. Avoid spurious precision; percentages should generally be given as integers.Analysis
There should be a clear description of which methods were used, and any analyses not in common usage should be supported by references. In general, 'non-parametric' analyses should be used, e.g. the Mann-Whitney test for comparing two groups and the Wilcoxon test for comparing the changes to a group.
Strive to limit the number of statistical tests performed, especially on subgroups. If you cannot avoid multiple comparisons, then use an appropriate adjustment to avoid a 'type 1' (false-positive) error. Results of statistical tests should be reported by stating the value of the test statistic (t), the number of degrees of freedom (df) and the P value to two decimal places, e.g. t = 1.34, 16 df, P = 0.20.Where possible, the results of the primary analysis should be reported using confidence intervals instead of, or in addition to, P values. Do not use statistical tests to compare the baseline characteristics of study groups, but rather use adjusted analyses to investigate the effect of such imbalances.
When reporting results involving small cohorts (<100 cases), avoid using decimal points (i.e. round up to nearest number) and report P-values with a maximum of three decimal places (e.g. 45 mm, P = 0.012). Proportions involving small cohorts should be reported as ratios (e.g. 2/15).Interpretation
Statistical significance should not be confused with clinical relevance. Use confidence intervals to assess clinical relevance, especially when interpreting a 'negative' finding. Do not place undue emphasis on secondary analyses, especially when they were suggested by an inspection of the data.
Short reports / case reports should now be submitted to EJVES Short Reports - this is a new open access journal launched by the ESVS as a companion to EJVES and is dedicated to publishing short reports, technical notes and videos of surgical techniques. The journal will be submitted to PubMed Central for indexing. Authors are expected to pay a fee for publication, which is USD500 and ESVS members can take up a 50% discount and pay only USD250. You can submit articles to EJVES Short Reports here: http://ees.elsevier.com/ejvssr.
Submitted short reports must contain a clear and convincing educational message and, upon submission, authors will be asked to declare exactly what new or innovative learning points are covered and why they merit publication. The assigned Associate Editor will then decide whether the manuscript is relevant enough to undergo external peer review or whether it should be rejected as it does not meet inclusion criteria or submitted to EJVES Short Reports where there is the space to publish short reports. The rejection rate for EJVES itself is expected to be extremely high due to a lack of space for these papers and the decision on whether to accept or reject a manuscript is final. Accordingly, please read the following instructions carefully before submitting your paper in order to avoid disappointment.
Short (case) reports should not exceed 750 words (excluding the abstract which should be < 100 words) and should be constructed according to the criteria described below:
• Please use double line spacing with automated line and page numbering, but avoid other kinds of automatic formatting.
• Front page with exact word counts of the structured abstract (maximum 100) and the text (maximum 750, excluding legends and references). Every submission should include an answer to the following question before the abstract: What unique educational message is provided and why is it relevant?Title page with authors’ (maximum 4) information and 3-6 keywords.
• Structured abstract (maximum 100 words) using the following headings:
Novel pathologies or technical innovations: Introduction – report – conclusion;
Technical notes: Introduction – technical summary – conclusion;
Best evidence topics: Clinical question – search method – results – conclusion.
• Paper including structured text body, references (maximum 5), tables (maximum 2) and legends for figures (maximum 2). The main text should follow the following format:

Each manuscript will undergo preliminary assessment by an Associate Editor. If it is not felt to be innovative enough, it will be rejected. Otherwise it will go out to peer review. For 'best evidence topics', a running list of potentially interesting clinical questions is being held at the editorial office for your consideration, and consultation with the editorial office prior to production of the paper is advised.
We encourage the submission of reviews and editorials. The maximum word count for reviews is 5,000 words including references and for editorials 1,000 words including references. Priority will be given to editorials addressing a current problem, systematic reviews and meta-analyses. We advise potential authors seeking advice on the suitability of topics to email the editorial office at firstname.lastname@example.org
EJVES has introduced a new type of article, called 'coup d'oeil'. This takes the form of a single interesting and informative image. A brief title should be supplied along with text describing the image using no more than 100 words. Two authors maximum and no references. Any image being considered for coup d'oeil should be submitted via the EJVES EES electronic submission website. Please note that any submission not complying with these criteria will be rejected.
The article should present a technical innovation, a novel procedure or a novel technical modification to or as part of a procedure. Please limit the word count to 300 words and two high quality images. There should be a maximum of 2 authors. No references are required. The article should be structured as: Introduction, Technique, Conclusion (an abstract is not required).
Letters, book reviews and forthcoming events
We welcome letters commenting on articles in the Journal and notification of forthcoming events, maximum 300 words including references. Email your letter or details of forthcoming events as an attached Word file to the editorial office at email@example.com.
Online proof correction
Corresponding authors will receive an e-mail with a link to our online proofing system, allowing annotation and correction of proofs online. The environment is similar to MS Word: in addition to editing text, you can also comment on figures/tables and answer questions from the Copy Editor. Web-based proofing provides a faster and less error-prone process by allowing you to directly type your corrections, eliminating the potential introduction of errors.
If preferred, you can still choose to annotate and upload your edits on the PDF version. All instructions for proofing will be given in the e-mail we send to authors, including alternative methods to the online version and PDF.
We will do everything possible to get your article published quickly and accurately. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. It is important to ensure that all corrections are sent back to us in one communication. Please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.
The corresponding author will, at no cost, receive a customized Share Link providing 50 days free access to the final published version of the article on ScienceDirect. The Share Link can be used for sharing the article via any communication channel, including email and social media. For an extra charge, paper offprints can be ordered via the offprint order form which is sent once the article is accepted for publication. Both corresponding and co-authors may order offprints at any time via Elsevier's Webshop. Corresponding authors who have published their article open access do not receive a Share Link as their final published version of the article is available open access on ScienceDirect and can be shared through the article DOI link.
