Vascular Specialist International (Vasc Specialist Int) is a peer-reviewed, open-access international journal published every quarter at the end of March, June, September, and December in printed version. In electronic version, each article is published online as soon as accepted for better accessibility. It includes original articles, review articles, case reports, technical notes, editorials, letters to the editor, invited commentaries, rapid communications, and images of vascular surgery in the field of vascular specialties. The journal is open to all research related to the peripheral vascular and lymphatic system, including vascular surgery, endovascular intervention, hybrid surgery, vascular medicine, angiology, basic research, diagnostic imaging, functional outcomes, and rehabilitation, among others.
Vasc Specialist Int adheres to the guidelines and best practices published by professional organizations, including the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals” (http://www.icmje.org/icmje-recommendations.pdf) by the ICMJE and the “Principles of Transparency and Best Practice in Scholarly Publishing” (joint statement by the COPE, DOAJ, WAME, and OASPA; http://doaj.org/bestpractice). The journal reserves the right to reject any manuscripts that do not meet the standards for publication.
Submission to Vasc Specialist Int are done online via the web submission system for this journal (http://www.vsijournal.org/submission). Authors must first register before logging into the online system, and once logged in, the system will guide them through the submission process step-by-step. Once the uploading is completed, the system automatically generates an electronic (PDF) proof, which is then used for reviewing. All correspondence, including the editor’s decision and request for revisions, will be done via e-mail. For any questions and concerns regarding the submission process, please contact the editorial office.

• 1) Recommended research reporting guidelines
  

  We recommend to use the six most widely used guidelines for reporting medical research findings. PRISMA for systematic reviews and meta-analyses, CONSORT for randomized controlled trials, STROBE for observational studies, STARD for diagnostic accuracy studies, CARE for case reports, and ARRIVE for animal research.

• 2) Disclosure of conflict of interest
  

  Conflict of interest has increasingly become a prominent issue in medical journal publications. Accordingly, all authors are required to report potential conflicts of interest that could inappropriately influence their work. This includes any financial (e.g., employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications, travel grants) or other relationships (e.g., academic or even personal) with commercial entities whose products or services are related to the subject matter in the manuscript, or to sociopolitical issues that could cause conflict. Such matters should be disclosed at the end of the manuscript, and the editor may use this information as a reference for editorial decisions.

• 3) Statements of human and animal rights, informed consent, and Institutional Review Board approval
  

  All research submitted to the journal must be conducted in accordance with high ethical norms. These include the protection of human and animal rights, confidentiality, and written informed consent. For human investigations, the principles outlined in the Declaration of Helsinki (https://www.wma.net/what-we-do/medical-ethics/declaration-of-helsinki/) should be followed, and approval from the Institutional Review Board (approval number) should be obtained. Written informed consent must be obtained from all subjects involved and should be included in the submitted article. Patient anonymity must be preserved and confidential information should never be published. If revealing Personally Identifiable Information (PII) is necessary for scientific purposes, then authors must provide a signed statement from the patient, granting approval for the publication of identifying materials, including photographs.
  If a study involves a clinical trial, the latter should be registered in a public database (e.g., the registration sites of the National Library of Medicine (http://www.clinicaltrials.gov) or the Korean National Institute of Health (http://cris.nih.go.kr/cris/index.jsp) prior to the enrollment of the first patient.
  For animal experiments, authors should confirm that the use of animals was approved by the Institutional Animal Ethical Committee or equivalent, and that the animal care complied with the “Guide for the Care and Use of Laboratory Animals” (Institute of Laboratory Animal Resources, Commission on Life Sciences, National Research Council (https://www.nap.edu/catalog/12910/guide-for-the-care-and-use-oflaboratory-animals-eighth).

• 4) Data sharing policy
  

  This journal follows the data sharing policy stipulated in the “Data Sharing Statements for Clinical Trials: A Requirement of the International Committee of Medical Journal Editors” (https://doi.org/10.3346/jkms.2017.32.7.1051). As of July 1, 2018, manuscripts submitted to ICMJE journals that report the results of interventional clinical trials must contain a data sharing statement, as described below. Clinical trials that begin enrolling participants on or after January 1, 2019, must include a data sharing plan upon registration. Any changes to the data sharing plan after registration must be ref lected in the statement submitted and published with the manuscript, and updated in the registry record. All authors of research articles that deal with interventional clinical trials must submit a data sharing plan. Depending on the extent of their data sharing plan, authors should deposit their data after deidentification and report the DOI of the data and the registered site.

• 5) Originality and publication ethics
  

  All manuscripts should be original in nature and must not have been previously published or be under consideration for publication in other scientific journals at the time of submission. All manuscripts should follow the publication ethics at all times. These include issues concerning plagiarism, data fabrication or falsification, citation manipulation, improper authorship contribution, duplicate submissions, and redundant submissions. All submitted manuscripts are inspected by Similarity Check powered by iThenticate (https://www.crossref.org/services/similarity-check/), a plagiarism detection tool. If a significantly high degree of similarity score is found, then the editorial board will perform a more in-depth content screening. Any violation of publication ethics may lead to automatic rejection (at the time of submission) or withdrawal (for previously published articles).

• 6) Authorship
  

  Vasc Specialist Int follows the 2019 recommendations for authorship by the ICMJE (http://www.icmje.org/recommendations/). Authorship credit should be based on the following: (1) substantial contributions to the conception or design of the work, or the acquisition, analysis, or interpretation of data for the work; (2) drafting the work or making crucial revisions for important intellectual content; (3) final approval of the version to be published; and (4) acceptance of full accountability for all aspects of the work in ensuring that any questions related to the accuracy or integrity of any part of the work are properly investigated and resolved. All authors should meet the four aforementioned criteria. In addition, each author should be accountable for the respective sections of the work they have done and should be able to identify which co-authors are responsible for other specific sections of the work. Authors should have confidence in the integrity of the contributions of their co-authors. All those who meet the four criteria should be identified as authors. Those who do not meet all four criteria should be acknowledged. The purpose of these authorship criteria is to reserve authorship status for those who deserve credit and take responsibility for the work.
  It may be considered as improper authorship if any of the authors have not made a substantial contribution to one of the nine core contributions (i.e., concept and design, analysis and interpretation, data collection, writing the article, critical revision of the article, final approval of the article, statistical analysis, obtained funding, and overall responsibility).
  Unjustified authorship includes ghost authorship or guest authorship. Ghost authorship refers to when an individual makes a substantial contribution to the research or writing of the report, but is not listed as an author. Ghost authorship is considered problematic because it may be used to conceal the participation of researchers with conf licts of interest. A ghostwriter may be concealed to obscure the industry sponsoring the research, improving the apparent objectivity of an article while maintaining the company’s control over its content. It is also considered as ghost authorship when mentors publish their students’ academic theses or doctoral dissertations without the students’ name.
  Other forms of unjustified authorship include “gift authorship,” “guest authorship,” “honorar y authorship,” “gratuitous authorship,” “loose authorship,” and more. This pertains to the inclusion of publication bylines of colleagues who have done little or no work in the conceptualization or development of a scientific project. For students and residents, participation in only a portion of a project considerably diminishes the educational experience and renders them ineligible for authorship at a certain point. Authorship should not be a reward for any form of participation, although individuals with less participation can and should be noted in the Acknowledgments. Mentors should ensure that students have the opportunity to be involved in and learn from the entire process.

• 7) Secondary publication
  

  Manuscripts can be republished if they satisfy the following condit ions of secondar y publication st ipulated in the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals” by the International Committee of Medical Journal Editors (ICMJE) (http://www.icmje.org/):
  (1) The authors have received approval from the editors of both journals (the editor concerned with the secondary publication must have access to the primary version).
  (2) The priority of the primary publication is respected by a publication interval negotiated by the editors of both journals and authors.
  (3) The manuscript for secondary publication is intended for a different group of readers; an abbreviated version could be sufficient.
  (4) The secondary version faithfully ref lects the data and interpretations of the primary version.
  (5) The secondar y version informs readers, peers, and documenting agencies that the manuscript has been published elsewhere in whole or in part—for example, with a note that might read, “This article is based on a study first reported in the journal title, with full reference, and the secondary version cites the primary reference.”
  (6) The title of the secondary publication should indicate that it is a secondary publication (complete or abridged republication or translation) of a primary publication. Of note, the United States National Library of Medicine (NLM) does not consider translations as “republications” and does not cite or index them when the original article was published in a journal that is indexed in MEDLINE. Process to manage the research and publication misconduct.

• 8) Managing cases of research and publication misconduct
  

  When the journal faces suspected cases of research and publication misconduct—such as a redundant (duplicate) publication, plagiarism, fabricated data, changes in authorship, undisclosed conf licts of interest, ethical concerns with the submitted manuscript, appropriation of an author’s idea or data by a reviewer, complaints against the editors, and other issues— it conducts a resolution process, which follows the flowchart provided by the Committee on Publication Ethics (http://publicationethics.org/resources/flowcharts). The editorial board shall discuss suspected cases and reach a decision. Any manuscripts that do not follow the guidelines for research and publication ethics are subject to sanctions, which are to be decided by the editorial board, and may include restriction on future submissions to the journal.
  For other policies on research and publication ethics not stated above, the journal follows the policies established by the Good Publication Practice Guidelines for Medical Journals from the Korean Association of Medical Journal Editors (http://www.kamje.or.kr), or the guidelines regarding research and publication ethics from either the International Committee of Medical Journal Editors (http://www.icmje.org) or the Committee on Publication Ethics (http://publicationethics.org/resources/international-standards-for-editors-and-authors).

  14. (14) Table preparation
      

      Manuscripts for publication should have a maximum of seven figures and tables. Tables should be numbered in the order in which they are cited in the text. Table citation in the text should be done in parentheses before a period/comma (e.g., “~ is shown (Table 1)”). Tables should be embedded in the manuscript file, and each table should start on a separate page and have a concise and explanatory title at the top. Only the first letter of the title should be capitalized, and there should be no punctuation marks at the end. Tables should be configured so as not to include borders (i.e., horizontal and vertical rows) inside the table. Any abbreviations used should be defined below the table as a footnote. Any symbols used should follow the order a, b, c, d, e, f, and the significance of each symbol should be stated below the table as a footnote.

  15. (15) Figure preparation
      

      The preferred file formats for the figures are .tif or .eps, although other formats, including .ppt, .jpg, .gif, .pdf are also acceptable. Each figure should be uploaded as a separate file with a minimum resolution of 300 dpi (dots per inch). Figures should be numbered in the order in which they are cited in the text, and figure citation in the text should be done in parentheses before a period/comma (e.g., “~ is good (Fig. 1)”). For figures with multiple panels, uppercase letters are used after each figure number (e.g., Fig. 1A, Fig. 1B). Figure legends should be provided separately and embedded in the manuscript. Each figure legend should have a short title and provide a full explanation of the figure. For microscope figures, the staining method and magnification power should be indicated in the legends, and scale bars should be embedded in the figures.

  16. (16) Appendix
      

      Additional material relevant to the research (e.g., questionnaires) can be included in the Appendix.

  17. (17) Supplemental files
      

      Any supplemental files, including methodologies, video clips, or appendices that could improve the understanding of the readers or reviewers should be uploaded separately through the online submission system.

• 5) Manuscript checklist
  

  A manuscript checklist is provided to help authors prepare the necessary materials for submission and make the online submission process as straightforward as possible (http://www.vsijournal.org/file/checklist.pdf). Manuscripts that do not meet these requirements will be returned to the author without a review.

• 1) Screening before review
  

  Manuscripts that do not fit the aims and scope of the journal or do not adhere to the instructions to the authors may be immediately returned to the author after receipt without a review. Some articles may require English editing to meet the standards of an international journal, which could not only delay the publication process, but also be a major reason for rejection. Therefore, authors who are less fluent in English writing are strongly advised to have their manuscripts proofread by Englishlanguage editing companies to improve the quality of the manuscript and increase the probability of acceptance.

• 2) Peer review process
  

  The journal adheres to a double-blind peer review policy wherein the authors’ names and affiliations are not disclosed to the reviewers, and the reviewers’ identities are kept confidential. All manuscripts are reviewed by at least two reviewers appointed by the editors and shall be informed of one of the following decisions: Accept, Major revisions, Minor revisions, and Reject. The peer review period is two weeks. The first decision is usually made within 1~2 weeks after the completion of the review. The editor-in-chief is responsible the final decision whether the manuscript is accepted or rejected.
  Editors who are involved in an article as authors or have any conflict of interest are excluded from the process of peer review and decision making regarding acceptance. If the editor-in-chief is involved, an associate editor takes on the former’s role and makes the final decision on acceptance.

• 3) Submission of revised manuscripts
  

  Manuscripts that require major or minor revisions should be resubmitted through the online submission system. Any revisions (if applicable) should be resubmitted within four weeks for reconsideration of publication at Vasc Specialist Int. Authors should indicate the changes made in the document by either using the “Track changes” function (preferred) in Microsoft Word (for .doc or .docx files) or by crossing out deleted phrases with a straight line (strikethrough) and using a red font for new phrases. The reviewers’ comments should also be addressed on a point-bypoint basis.

• 4) After acceptance
  

  If a manuscript is finally accepted, it will be sent back to the corresponding author for another round of proofreading after it undergoes professional manuscript editing and/or English proofreading. Proofreading should be conducted again for any misspellings or errors by the authors.

• 5) Feedback after publication
  

  The authors or readers could inform the Editorial Board regarding any errors or content that should be revised. The Editorial Board may consider the erratum, corrigendum, or retraction. If there are any revisions to the article, there will be a CrossMark description to announce the final draft. Any reader’s opinion on the published article in the form of a letter to the editor will be forwarded to the authors. The authors may reply to readers’ letters. Subsequently, the letter to the editor and the author’s reply may also be published.

• 6) Process for appeals
  

  The policy of the journal is primarily aimed at protecting the authors, reviewers, editors, and publishers of the journal. Appeals may be submitted to office@vsijournal.org. Appeals received by the editorial office are discussed by the editorial board members, and the results are subsequently dispatched to the submitter. The process of handling complaints and appeals follows the guidelines of the Committee of Publication Ethics (https://publicationethics.org/appeals).

There are no author submission fees or other publication-related charges. All costs for the publication process are shouldered by the publisher. Authors may request additional reprints of their articles, in which case additional charges may be applied. The cost of colored figures for paper offprints will be shouldered by the authors.
