The Artery of Adamkiewicz is the largest anterior segmental medullary artery. It arises from a left posterior intercostal artery, which branches from the aorta, and supplies the lower two thirds of the spinal cord via the anterior spinal artery. In some percentage of people, the Artery of Adamkiewicz sometimes arises from a lumbar vessel.

It is also referred to as Adamkiewicz artery, major anterior segmental medullary artery, artery of the lumbar enlargement, great radicular artery of Adamkiewicz, great anterior radiculomedullary artery, and great anterior segmental medullary artery.

If the Artery of Adamkiewicz is damaged or obstructed, it can result in anterior spinal artery syndrome, causing loss of urinary and fecal control and impaired motor function of the legs. Sensory function is often preserved to a degree.

It is crucial to identify the location of the artery (using computed tomographic angiography) when repairing an abdominal aortic aneurysm because it can easily be severed.

It is named for Albert Wojciech Adamkiewicz (August 11, 1850 - October 31, 1921), a Polish pathologist who was born in Żerków.
