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.
Djindjian et al. described the filum terminale artery as a continuation of the artery of Adamkiewicz, which after giving branches and doing anastomoses with posterior spinal artery at the level of conus, continues as a longitudinal artery on the ventral surface of the filum terminale 1).
Neuronal degenerations secondary to vasospasm of Adamkiewicz artery vasospasm induced Onuf's nucleus-pudental nerve ganglia complex degeneration may be a reason of urinary retention following spinal SAH.
