It coursed posteriorly towards the lamina terminalis region, curving superiorly to the subcallosal area. The ScA gave off many branches to provide the main blood supply to the subcallosal region. Importantly, it supplies the septal\/subcallosal region bilaterally. The ScA can be found posterior, superior, or inferior to the AcomA when using a transylvian, interhemispheric, or endonasal approach, respectively. In specimens with no ScA (21%), the median callosal artery (MdCA) was the dominant artery arising from the AcomA. It followed an identical course to the ScA, providing supply to the same structures bilaterally, but its distal extension reached the body\/splenium of the corpus callosum. The MdCA is a ScA variant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>The ScA is a unique vessel because it supplies the septal\/subcallosal region bilaterally; preservation of this vessel during surgery is crucial for successful outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ons\/opy276","type":"journal-article","created":{"date-parts":[[2018,12,18]],"date-time":"2018-12-18T00:54:42Z","timestamp":1545094482000},"page":"79-87","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":9,"title":["Surgical Anatomy of the Subcallosal Artery: Implications for Transcranial and Endoscopic Endonasal Surgery in the Suprachiasmatic Region"],"prefix":"10.1227","volume":"17","author":[{"given":"Edinson","family":"Najera","sequence":"first","affiliation":[{"name":"Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joao T","family":"Alves Belo","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huy Q","family":"Truong","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A","family":"Gardner","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan C","family":"Fernandez-Miranda","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"},{"name":"Department of Neurosurgery, Stanford University School of Medicine, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2019,7]]},"reference":[{"key":"bib1-20240909","first-page":"562","article-title":"The blood vascular system","author":"Senior","year":"1923","journal-title":"Human anatomy Philadelphia: Blakiston's Son"},{"issue":"5","key":"bib2-20240909","doi-asserted-by":"crossref","first-page":"533","DOI":"10.1097\/00005053-194411000-00044","article-title":"The anterior communicating artery in man","volume":"100","author":"Rubinstein","year":"1944","journal-title":"J Nerv Ment Dis"},{"issue":"6","key":"bib4-20240909","doi-asserted-by":"crossref","first-page":"1211","DOI":"10.1097\/00006123-199706000-00019","article-title":"Microsurgical anatomy and clinical significance of the anterior communicating artery and its perforating branches","volume":"40","author":"Serizawa","year":"1997","journal-title":"Neurosurgery"},{"issue":"12","key":"bib5-20240909","doi-asserted-by":"crossref","first-page":"2293","DOI":"10.3174\/ajnr.A4057","article-title":"MR imaging of subcallosal artery infarct causing amnesia after surgery for anterior communicating artery aneurysm","volume":"35","author":"Mugikura","year":"2014","journal-title":"AJNR Am J Neuroradiol"},{"issue":"1-2","key":"bib6-20240909","doi-asserted-by":"crossref","first-page":"78","DOI":"10.1007\/BF01809337","article-title":"Branches of the anterior communicating artery","volume":"106","author":"Marinkovi\u0107","year":"1990","journal-title":"Acta Neurochir"},{"issue":"1","key":"bib7-20240909","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1007\/s00234-014-1438-8","article-title":"Subcallosal artery stroke: infarction of the fornix and the genu of the corpus callosum.
