The anatomy of the anterior spinal artery in pigs was studied to determine whether or not the artery was continuous, as it is humans, or discontinuous. Six porcine carcasses were embalmed, and 24 hr later injected with pigmented latex through the thoracic aorta. The spinal column was removed, and the spinal cord was dissected with analysis of the anterior spinal artery. In all cases, the artery was continuous, and perfused by 18 ± 3 medullary arteries. The pig would thus be suitable as a model for the study of human diseases in which the anatomy of the anterior spinal artery is a factor. © 1992 Wiley‐Liss, Inc.
