In [[human anatomy]], the '''artery of Adamkiewicz''' (also '''arteria radicularis magna''') is the largest [[anterior segmental medullary artery]] and the dominant segmental feeding vessel to the thoracic cord, supplying the anterior aspect of the cord (from T8 to the conus medullaris) via the anterior spinal artery.<ref name=Moore298>{{cite book|last=Moore|first=Keith|title=Essential Clinical Anatomy, Third Edition|year=2007|publisher=Lippincott Williams & Wilkins|isbn=978-0-7817-6274-8|pages=298|author2=Anne Agur}}</ref> It is a radiculomedullary artery arising from the spinal [[Posterior (anatomy)|dorsal]] branch of the segmental artery (posterior intercostal, subcostal, or lumbar artery), which in turn arises from the descending aorta.<ref>{{cite journal |last1=Yoshioka |first1=K |last2=Niinuma |first2=H |last3=Ehara |first3=S |last4=Nakajima |first4=T |last5=Nakamura |first5=M |last6=Kawazoe |first6=K |title=MR angiography and CT angiography of the artery of Adamkiewicz: state of the art. |journal=Radiographics |date=October 2006 |volume=26 Suppl 1 |pages=S63-73 |doi=10.1148/rg.26si065506 |pmid=17050520}}</ref> It typically arises from a 9th to 11th left [[posterior intercostal artery]],<ref name="takase">{{cite journal |last1=Takase |first1=K. |last2=Sawamura |first2=Y. |last3=Igarashi |first3=K. |last4=Chiba |first4=Y. |last5=Haga |first5=K. |last6=Saito |first6=H. |last7=Takahashi |first7=S. |year=2002 |title=Demonstration of the Artery of Adamkiewicz at Multi- Detector Row Helical CT |journal=Radiology |volume=223 |issue=1 |pages=39–45 |doi=10.1148/radiol.2231010513 |pmid=11930046}}</ref> enters through the L2-L3 [[intervertebral foramen]] to join the [[anterior spinal artery]] and supply much of the inferior half of the [[spinal cord]].<ref name=":0">{{Cite book |last1=Patestas |first1=Maria A. |title=A Textbook of Neuroanatomy |last2=Gartner |first2=Leslie P. |publisher=Wiley-Blackwell |year=2016 |isbn=978-1-118-67746-9 |edition=2nd |location=Hoboken, New Jersey |pages=70}}</ref> The artery is named after pathologist [[Albert Wojciech Adamkiewicz]].
