Only a few classic studies published in the last century have investigated these collaterals. The current work proposes a possible classification of these vessels and analyzes their relative abundance along spinal cord segments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Human spinal cords (<jats:italic>n<\/jats:italic> = 30) from male and female cadavers were injected with colored latex through the vertebral, ascending cervical, costocervical trunk and segmental arteries and then fixed in formaldehyde solution. Afterwards, spinal vessels were dissected and the relative abundances of each type of collateral were quantified and compared between different spinal cord segments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Collaterals of the anterior longitudinal pathway can be classified as central arteries and arteries for the anterior and lateral columns. Collaterals for the anterior column can be classified into two types: anteromedial and anterolateral. Arteries for the lateral column can be classified, according to their relationship with the dentate ligament, as either preligamentous or post\u2010ligamentous. The collaterals of posterior longitudinal pathways can be divided between those for the posterior and those for the lateral column. In turn, the arteries for the posterior column can be classified into three types: median posterior, posteromedial and posterolateral. The collaterals for the lateral column were also classified as either pre\u2010 or post\u2010ligamentous.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The relative abundance of the various types of collateral and anastomoses between longitudinal pathways was inhomogeneous along the spinal cord, with several statistically significant differences observed between spinal segments.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ca.23622","type":"journal-article","created":{"date-parts":[[2020,5,19]],"date-time":"2020-05-19T20:03:23Z","timestamp":1589918603000},"page":"596-604","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Anatomical study of the pial arterial network in human spinal cords"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1834-7822","authenticated-orcid":false,"given":"Santiago","family":"Rojas","sequence":"first","affiliation":[{"name":"Unit of Human Anatomy and Embriology, Department of Morphological Sciences, Faculty of Medicine Universitat Aut\u00f2noma de Barcelona  Cerdanyola del Vall\u00e8s Spain"},{"name":"Serra H\u00fanter Fellow  Universtitat Aut\u00f2noma de Barcelona Cerdanyola del Vall\u00e8s Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marisa","family":"Ortega","sequence":"additional","affiliation":[{"name":"Unit of Human Anatomy and Embriology, Department of Morphological Sciences, Faculty of Medicine Universitat Aut\u00f2noma de Barcelona  Cerdanyola del Vall\u00e8s Spain"},{"name":"Institute of Legal Medicine and Forensic Sciences of Catalonia Hospitalet de Llobregat  Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9181-5613","authenticated-orcid":false,"given":"Alfonso","family":"Rodr\u00edguez\u2010Baeza","sequence":"additional","affiliation":[{"name":"Unit of Human Anatomy and Embriology, Department of Morphological Sciences, Faculty of Medicine Universitat Aut\u00f2noma de Barcelona  Cerdanyola del Vall\u00e8s Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,6,21]]},"reference":[{"issue":"3","key":"e_1_2_7_2_1","first-page":"101","article-title":"Die Blutgefasse des menschlichenruckenmarkes II: Theil. diegefasse der ruckenmarksoberflache","volume":"85","author":"Adamkiewicz A.","year":"1882","journal-title":"S B Heidelberg AkadWiss"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2.2.137"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ca.22281"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ca.22284"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02133005"},{"key":"e_1_2_7_7_1","volume-title":"Anatomie et pathologie art\u00e9rielles de la moelle","author":"Corbin J.
