In human anatomy, the artery of Adamkiewicz (also arteria radicularis magna) is the largest anterior segmental medullary artery. The artery is named after Albert Wojciech Adamkiewicz (August 11, 1850 – October 31, 1921) a Polish-Jewish pathologist born in Żerków. It has several other names, including: * Adamkiewicz artery * great radicular artery of Adamkiewicz * major anterior segmental medullary artery * artery of the lumbar enlargement * great anterior radiculomedullary artery * great anterior segmental medullary artery It typically arises from a left posterior intercostal artery at the level of the 9th to 12th intercostal artery , which branches from the aorta, and supplies the lower two thirds of the spinal cord via the anterior spinal artery. ==Anatomical variations== The spinal cord vasculature has a complex and highly variable anatomy. In a study of approximately 70 people that examined the spinal cord's blood supply it was found that:〔 # The Adamkiewicz artery sometimes arises from a lumbar vessel. # In approximately 30% of people it arises from the right side. # One quarter of people have two large anterior segmental medullary arteries. In 75% of people, the artery of Adamkiewicz originates on the left side of the aorta between the T8 and L1 vertebral segments. In an extensive literature review, recognition of the AKA using CT and/or MR was achieved in 466 of 555 cases (83.96%)and in 384 (83.3%) cases the AKA originated from a left intercostal artery. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Artery of Adamkiewicz」の詳細全文を読む スポンサード リンク
