We investigated the anatomical distribution pattern of intraspinal arteries.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>Twenty fresh, non-embalmed cadaveric human bodies were studied. Anatomical dissection and investigation of the epidural arterial network were performed according to a standardized protocol. We used a generalized mixed linear model to test whether the presence probability for certain vessels differed between vertebrae\/segments.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>There was craniocaudal continuity of all ipsilateral longitudinal connections from T1 to L5 by the anterior radicular artery. The mean [\u00b1standard deviation (SD)] number of transverse anastomoses was 9.7\u2009\u00b1\u20092.1. The presence probability of transverse anastomoses along the spine was different between vertebrae (P\u2009&amp;lt;\u20090.0001). There were 2 distribution peaks along the spine: 1 peak around T4\u2013T6 and 1 around T11. The mean (\u00b1SD) number of thoracic and lumbar anterior radiculomedullary arteries (ARMAs) was 3.0\u2009\u00b1\u20091.1. The probability of the presence of ARMAs along the spine was different for each vertebral segment (P\u2009&amp;lt;\u20090.0001). Between ARMAs there were gaps of up to a maximum of 9 vertebrae. All Adamkiewicz arteries were located caudally to T7. The median segment of the Adamkiewicz presence was T10\/11.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The epidural collateral network shows craniocaudal continuity. The number of transverse anastomoses is high. The number of ARMAs is low, and there is considerable variation in their distribution and offspring, which is highly likely to impact perfusion during segmental artery sacrifice when treating thoraco-abdominal aortic disease.<\/jats:p>\n
