Table of Contents


The Journal of Cerebrovascular and Endovascular Neurosurgery (JCEN) is the official journal of the Korean Society of Cerebrovascular Surgeons (KSCVS) and the Korean NeuroEndovascular Society (KoNES, is changed from SKEN in 2020). ‘Korean Journal of Cerebrovascular Surgery’ was launched in 1998 and ‘Journal of Korean Society of Intravascular Neurosurgery’ was in 2006. The joint venture between ‘Korean Journal of Cerebrovascular Surgery’ and ‘Journal of Korean Society of Intravascular Neurosurgery’ is effective as of March 2012 with all new publications following the Volume, Number, ISSN and EISSN of ‘Korean Journal of Cerebrovascular Surgery’ and abbreviated title of ‘J Cerebrovasc Endovasc Neurosurg’. This journal publishes papers dealing with clinical or experimental works on cerebrovascular disease. Accepted papers will include original work (clinical and laboratory research), case reports, technical notes, review articles, letters to the editor, and other information of interest to cerebrovascular neurosurgeon. Review articles can also be published upon specific request by the journal. Full text is freely available from: The subscription fee of this journal is free for the members of KSCVS and KoNES. Quarterly publication is available in March 31, June 30, September 30 and December 31 each year. Full or limited viewing of the articles in this journal is abstracted in PubMed/PubMed Central, KoreaMed, KoreaMed Synapse, KOMCI, Google Scholar, KOFST(ENEST), and EBSCO.


1) Duplicate or Redundant Publication

The Council of Science Editors defines redundant publication as “reporting (publishing or attempting to publish) substantially the same work more than once, without attribution of the original source(s)” (CBE Views 1996;19(4):76-77). Characteristics of reports that are substantially similar include (1) “at least one of the authors must be common to all reports”; (2) “the subject or study populations are often the same or similar”; (3) “the methodology is typically identical or nearly so”; and (4) “the results and their interpretation generally very little, if at all.”
Similar to other journals, the JCEN also considers as redundant or duplicate publication any work that was previously published in a language other than English, unless full disclosure was initially made by the authors and the Editor-in-Chief agreed to publish and so identified this material. A determination of redundant or duplicate publication will result in immediate rejection of the article and notification of the Editor(s) of other journals involved.

2) Plagiarism

The World Association of Medical Editors defines ‘Plagiarism’ as the use of others’ published and unpublished ideas or words (or other intellectual property) without attribution or permission, and presenting them as new and original rather than derived from an existing source. When an idea or words are taken from abstracts, research grant applications, Institutional Review Board applications, or unpublished or published manuscripts in any publication format (print or electronic), this misleads the reader as to the contributions of the plagiarizer. Since plagiarism is a scientific misconduct, when plagiarism is detected at any time before publication, the JCEN Editorial Office will request the author to either cite the original source or rewrite the section. If the plagiarism is extensive (i.e. > 25% of the original submission), the editors will take appropriate action to notify both readers and the author’s employers of the infraction.

3) Double-blind Peer Review System

JCEN operates a double-blind peer review system, where both authors and reviewers remain anonymous. If you submit the revision of your manuscript to another Board journal, we can forward the reviews of your manuscript to the affiliated journal upon request. The JCEN editorial board will make the final decision of publication for the submitted manuscripts, and can request any further corrections, revisions, and deletions to the article text if necessary.

4) Embargo Policy

Strict confidentiality is imposed on all the contents of accepted manuscripts and proposed dates of the publications. Before the articles appear electronically on the JCEN website or are distributed in the printed form of the JCEN journal, the authors are prohibited from releasing this information in either print or electronic forms to the media (i.e. television, radio, magazines, newspapers, etc.).
Along with the JCEN embargo policy, the authors must abide by any external embargo policies on the contents of their manuscripts or data used in the manuscript. With the preceding conditions in mind, the authors may present and discuss manuscripts to other clinicians/ researchers. Also, do not submit to the JCEN journal if the manuscript contains any restrictions that would prohibit prompt publication upon acceptance.
For the policies on the research and publication ethics not stated in these instructions, International standards for editors and authors ( can be applied.


All manuscripts must be submitted to the official JCEN website at

We strongly encourage the authors to provide publication-quality, high-resolution images to ensure the highest-quality reproduction of the figures in the JCEN. However, we are not responsible for the quality of images in print if the submitted figures do not satisfy the JCEN’ recommendation/ requirements. If you have questions, please consult a graphics specialist.

1) File Requirements

Photographs should be submitted individually (Namely, if Figure 1 is divided into A, B, C and D, do not combine them into one, but submit each of them separately). If the quality of the photographs is considered as inappropriate for printing, resubmission of them can be requested by the journal. Authors should submit figures in black and white if they want them to be printed in black and white. Authors are responsible for any additional costs of producing color figures. The description of each figure should be stated separately and attached to the end of the article text.
Submitted as a separate file, each figure must be saved with an appropriate figure number as the file name (i.e. Fig. 1A.jpg). If the figure contains more than one part, authors should combine them in the correct orientation, and for all figures containing more than 2 parts, please designate appropriate letters to figure parts.

2) Resolution

  • For JCEN submission, publication-quality figures should be at the following resolutions:
  • • Line Art (Image composed of lines and text without tonal or shaded areas): 1200 dpi
  • • Halftones (A continuous tone photograph, which contains on text): 300 dpi
  • • Combo (Image contains halftone+ text or line art elements): 600 dpi
  • • PMC: 500 dpi

3) Color Mode

The JCEN requires the RGB color mode for all color files.

4) Fonts

The authors are responsible for all spelling error in the figures. Please check all figures for spelling errors before submission. If we detect a spelling error that cannot be corrected, we will return the figure to the authors for correction. We recommend a prompt response from the authors to avoid any delays in the publication process.

5) Photographs

The JCEN requires omission of all identity revealing information in photographs of all study participants (patients or healthy volunteers). For all submissions with photographs leading to identification of the participants, the authors must obtain the patient consent form. If the participant is younger than 20 years of age, infirm, or dead, an authorized guardian must sign the form. See Studies Involving Humans in Special Considerations for more information. We request that the authors either fax or email the signed consent forms to the Editorial Office, or upload with the submission files.

6) Electron Micrographs and Photomicrographs

For submission with electron micrographs, please provide measurement bars indicating the original magnification and with photomicrographs, please include a legend stating the original magnification and the type of staining method used.


The authors must submit ‘Registration and Copyright Assignment Agreement Form’ (Download at and ‘ICMJE Form for Disclosure of Potential Conflicts of Interest’ (Download at The authors can upload these completed and signed forms during submission. For all missing documentations, the authors will be contacted by the JCEN Editorial Board. Therefore, it is important for the corresponding author to verify his/her email, as well as the contact information of all of the coauthors. If an author is deceased prior to publication of the manuscript, we require that next of kin complete and sign ‘Registration and Copyright Assignment Agreement Form’ and ‘ICMJE Form for Disclosure of Potential Conflicts of Interest’ on behalf of the deceased author.


After the manuscript has been accepted for publication, the corresponding author must be available to respond to questions that may arise during editing and composition.

If scientific misconduct is proven, JCEN reserves the right to retract the published article.

4) Sharing of Resources and Data

Authors must agree to share the methods and materials necessary to reproduce laboratory experiments and clinical trials, to verify and build on the findings of the studies, to use in academic and noncommercial research as a condition of publication.

(1) Methods
This section includes sufficient details of the methods used in the study for repetition by qualified investigators. While it is appropriate to refer to previous works with similar materials and methods, this section should include enough information for the reader to understand methods used to achieve the study goals without referring to other authors’ works.

For methods that have been previously published in another article or book, please cite that publication along with a brief description of the methods provided in the manuscript. This brief description should contain enough information for the reader to understand the methods used. For extra information that would beneficial for replication of this study should be made available for use by other researchers via an accessible database, personal/professional website, email, or other means.

(2) Materials
For academic and noncommercial research purposes, the authors are expected to freely share materials generated in their laboratories, such as cell lines, reagents, and other items that are not readily available. For all materials, the authors are expected to identify the source/provider of the materials.

(3) Data
For academic and noncommercial research purposes, the authors must make their data (i.e. high-resolution structural data and nucleotide sequences) available insofar as possible.
For all clinical trials and studies involving microarrays, registration is required. The registry name and number must be specified in the manuscript and in the appropriate place in the manuscript submission site. See Studies Involving Humans for additional information.

5) Studies Involving Humans

All submitted manuscripts to JCEN involving patients or healthy volunteers must adhere to the principles set forth in the World Medical Association Declaration of Helsinki ( Please include in the Methods section that the protocol followed adheres to these principles.

(1) IRB approval
Please include in the Methods section a statement showing that the relevant institutional review board (IRB) or ethics committee approved the study protocol. At the time of submission, the human subjects’ assurance number or equivalent identifier is required.

(2) Informed consent
Please include in the Methods section a statement showing that informed consent was obtained from the study participant (patient or healthy volunteer) or, in the case of an underage (younger than 20 years of age) or incapacitated participant, from the person authorized to give consent (i.e. the legal guardian or next of kin).

(3) Clinical trials
In accordance with ICMJE, all interventional clinical trials (A prospective study involving at least 1 treatment group and 1 comparison group receiving another treatment or no treatment) should be registered. Please include the registration number of the clinical trial and the name and URL of the registry in the Methods section of the manuscript and at the end of the Abstract. JCEN cannot accept manuscripts for review for unregistered clinical trials before patient enrollment. Please refer to the World Health Organization ( to provide the minimal registration data set. All specific sources of funding for the clinical trial should be clearly stated in their manuscripts. For report on randomized trial results, please refer to the Revised CONSORT Statement and follow the design of the CONSORT flow chart and the checklist of items to include (

6) Confidentiality of Patient Identity

The use of personal information in JCEN journals must be comply with the Personal Information Protection Act, available online at

(1) Names and identifiers
All patients and healthy volunteers must remain anonymous (See ‘Exceptions’). Any names, initials, dates of birth, resident registration numbers, or other coding numbers revealing the reader to patients’ or healthy volunteers’ identity should not be included in the manuscript’s text, figures, and tables and in any supplementary materials. The JCEN requires specific dates of hospital stay to be excluded, but allows month and year showing the time course of a disease or treatment.

(2) Photographs, imaging studies
All photograph or imaging data revealing the identity of all study participants (patients or healthy volunteers) must be excluded. For preserving patient confidentiality, it is not sufficient to use photographs that only mask out their eyes. The general rule of thumb is that the study participants viewing photographs for submission should not be able to readily identify themselves. All patient/volunteer names, identifying numbers, and dates of imaging studies must be excluded.

(3) Pedigrees
When submitting pedigrees to the JCEN, the authors are required to conceal the identity of the patients and their family members. Preserving the scientific integrity of the report, the authors may report less specific data for protection of patient confidentiality. Please state omission of identifiable information for patient confidentiality in the manuscript.

(4) Exceptions - use of identifiers
For all manuscripts containing recognizable images or other identifiable data, the JCEN require the authors to obtain a written approval of publication (in print and electronic forms) of identifiable information from the study participant or, in the case of participants younger than 20 years of age or incapacitated/ deceased, the authors may obtain the written approval of publication from the legal guardian or next of kin, respectively.

7) Studies Involving Animals
