About this Research Topic

Background

Cerebral and spinal vascular malformations are a spectrum of diseases in the central nervous system (CNS), including arteriovenous malformation (AVM), cavernous malformation (CM), and developmental venous anomaly (DVA), which are characterized by abnormal vascular structures with angiogenic and inflammatory dysfunction. Our current mechanistic understanding of vascular malformations is mainly based on sporadic human disease samples and animal models with inherited gene dysfunction. Surgical management consisting of open surgery, stereotactic radiosurgery, and endovascular surgery is still the primary treatment modality for these diseases. Recent advances fuel our research and management targets. The second-hit hypothesis of vascular malformation development is evolutionary from gene mutations to subsequent cellular interplay and specific cellular or molecular signature. The anatomical and hemodynamic knowledge is advancing the excellence of surgical management. More eloquent lesions are being treated with no neurological deficit. This Research Topic is to highlight research by leading scientists of the future across the entire breadth of vascular malformations to present the state-of-the-art understanding, methodology, and technique from bench to bedside.

This Research Topic aims to review the history, discuss the current understanding and treatment modalities, and provide future directions for vascular malformations in the central nervous system. Recent genomic and transcriptomic advances at single-cell and bulk levels identify novel somatic mutations in sporadic vascular malformations and unravel new cell types and specific cross-talk between cell components. Additionally, the correlation between these new findings and classical disease models further convinces our knowledge of the development of vascular malformations. These molecular and cellular findings are promoting novel research models and therapeutic targets for vascular malformations to a new era. The treatment strategy and risk assessment system of both surgical and natural history will embrace an innovation of integrative molecular and radiomics classification for vascular malformations in the future. More collaborations between neurosurgeons (who obtain varied tissue samples for research and know the question of clinical importance), neurologists(who would be the future with therapeutic treatment), bioinformaticians (who can mine the high thorough-put data), radiologists(who find new imaging technique to define molecular and clinical features) and molecular biologist (who consolidate all the understandings of underlining mechanism), will contribute to more translational research to conquer the CNS vascular malformations.

The scope of this Research Topic is to explore the management and mechanism of CNS vascular malformation and relevant diseases for the improvement of patient care. We are interested in manuscripts that describe pathophysiology, etiology, epidemiology, diagnosis, surgical or medical therapies, and prognosis. Areas of interest for this Topic include but are not limited to:
-The biology of arteriovenous malformation, cavernous malformation, telangiectasia, and venous anomaly
-The natural history and epidemiology of CNS vascular malformations
-The diagnostic or prognostic biomarkers for CNS vascular malformations
-The imaging features and techniques for CNS vascular malformations
-The treatment modality and outcome for CNS vascular malformations
-The novel technique with an application to CNS vascular malformations
-The neuroplasticity and brain function in CNS vascular malformations
-The interplay or cross-talk among neuron-glia, vascular and immune cells in CNS vascular malformations
We welcome Original Research, Reviews, Systematic Reviews or Meta-analyses, and Case Reports.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
