The swine is a well-established large-animal model due to its anatomical similarities with humans. The atlas begins with a concise overview of the femoroiliac arterial tree and the aorta, followed by a focused description of the common carotid and subclavian arteries, and finally the cephalic arteries\u2014both intracranial and extracranial. Average lengths and diameters of the cephalic arterial segments in pigs (30\u201380\u2009kg) were retrospectively determined from 3D rotational angiographies acquired in five animals previously used in experimental studies. Anatomical descriptions are supported by schematic diagrams and volume rendering reconstructions. This reference tool is designed to standardize anatomical understanding, enhance the effective use of the pig model, and minimize animal distress in experimental procedures. It serves as a valuable resource for practitioners in neurointerventional surgery.<\/jats:p>","DOI":"10.1136\/jnis-2025-024149","type":"journal-article","created":{"date-parts":[[2025,10,5]],"date-time":"2025-10-05T17:20:34Z","timestamp":1759684834000},"page":"1940-1947","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Practical arterial atlas of the pig for neurointerventional simulation"],"prefix":"10.1136","volume":"18","author":[{"given":"Mirella","family":"Merlette","sequence":"first","affiliation":[{"name":"Department of Radiology, Rouen University Hospital, F-76000 Rouen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0902-3375","authenticated-orcid":false,"given":"Aymeric","family":"Rouchaud","sequence":"additional","affiliation":[{"name":"Department of Radiology, Limoges University Hospital, CHU Dupuytren, Limoges, France"},{"name":"XLIM UMR CNRS No. 7252, Limoges University, Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charbel","family":"Mounayer","sequence":"additional","affiliation":[{"name":"Department of Radiology, Limoges University Hospital, CHU Dupuytren, Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8712-8431","authenticated-orcid":false,"given":"Eimad","family":"Shotar","sequence":"additional","affiliation":[{"name":"Department of Interventional Neuroradiology, Hopitaux Universitaires Pitie Salpetriere-Charles Foix, Paris, France"},{"name":"Sorbonne Universit\u00e9, INSERM, Institut de la Vision, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9473-9644","authenticated-orcid":false,"given":"Chrysanthi","family":"Papagiannaki","sequence":"additional","affiliation":[{"name":"Department of Radiology, Rouen University Hospital, F-76000 Rouen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claude","family":"Couquet","sequence":"additional","affiliation":[{"name":"XLIM UMR CNRS No. 7252, Limoges University, Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4797-9693","authenticated-orcid":false,"given":"G\u00e9raud","family":"Forestier","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, Clermont-Ferrand University Hospital, Clermont-Ferrand, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederic","family":"Crampon","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, Rouen University Hospital, F-76000 Rouen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabeth","family":"Garrido","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Rouen University Hospital, F-76000 Rouen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emmanuel","family":"Gerardin","sequence":"additional","affiliation":[{"name":"Department of Radiology, Rouen University Hospital, F-76000 Rouen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6442-8239","authenticated-orcid":false,"given":"Fr\u00e9d\u00e9ric","family":"Claren\u00e7on","sequence":"additional","affiliation":[{"name":"Department of Interventional Neuroradiology, Hopitaux Universitaires Pitie Salpetriere-Charles Foix, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8726-265X","authenticated-orcid":false,"given":"Julien","family":"Burel","sequence":"additional","affiliation":[{"name":"Univ Rouen Normandie, Normandie Univ, Inserm U1245 and CHU Rouen, Department of Radiology, F-76000 Rouen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2025,10,5]]},"reference":[{"key":"2026081703402621000_18.9.1940.1","doi-asserted-by":"publisher","DOI":"10.1136\/jnis-2023-020193"},{"key":"2026081703402621000_18.9.1940.2","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A8188"},{"key":"2026081703402621000_18.9.1940.3","doi-asserted-by":"crossref","DOI":"10.3389\/fneur.2022.925763","article-title":"The human placenta as a model for training and research in mechanical thrombectomy: Clarifications and use of the chorionic plate veins","volume":"13","author":"Burel","year":"2022","journal-title":"Front Neurol"},{"key":"2026081703402621000_18.9.1940.4","doi-asserted-by":"publisher","DOI":"10.1007\/s003300050545"},{"key":"2026081703402621000_18.9.1940.5","doi-asserted-by":"publisher","DOI":"10.1136\/neurintsurg-2015-012173"},{"key":"2026081703402621000_18.9.1940.6","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1016\/j.neurad.2020.03.003","article-title":"Intra-arterial in-situ bevacizumab injection effect on angiogenesis.
