In human anatomy, the Artery of Adamkiewicz, also Adamkiewicz artery, major anterior segmental medullary artery and great anterior segmental medullary artery, is the largest anterior segmental medullary artery.

It typically 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.^[1]

[edit] Anatomical variation

In a study of approximately 70 people that examined the spinal cord's blood supply it was found that^[1]:

1. The Adamkiewicz artery sometimes arises from a lumbar vessel.
2. In approximately 30% of people it arises from the right side.
3. One quarter of people have two large anterior segmental medullary arteries.

[edit] Disorders

When damaged or obstructed, it can result in anterior spinal artery syndrome,^[2] with loss of urinary and fecal continence and impaired motor function of the legs; sensory function is often preserved to a degree.
