Fig 1. Postmortem spinal cord specimen of the anterior cord surface, on which both the superficial spinal cord arteries and veins are shown. The great anterior radiculomedullary artery (ie, the Adamkiewicz artery [AKA]) (white arrow) and anterior spinal artery (ASA) (white arrowheads) are displayed on the right side of the image. The anterior median vein (AMV) (black arrowheads) as well as the great anterior radiculomedullary vein (GARV) (black arrow) are displayed on the left side. Note the close anatomic relation between the AMV and ASA as well as the similarity in the configuration of the AKA and GARV, respectively. Clotted blood is present in the veins and ASA. No blood is present in the AKA (white appearance) because of the preparation process. (Used with permission.)
