The ASA is particularly dependent on blood supply from the radicular arteries that originate from the thoracic aorta, such as the artery of Adamkiewicz. Thoracic aortic surgery can result in reduced blood flow through the radicular arteries (eg, from aortic cross-clamping and/or systemic hypotension) and consequently lead to anterior spinal cord infarction.
