Spinal cord ischemia following operations on the abdominal aorta Anthony L. Picone, M.D., Ph.D., Richard M. Green, M.D., John R. Ricotta, M.D., Allyn G. May, M.D., James A. DeWeese, M.D. Journal of Vascular Surgery Volume 3, Issue 1, Pages 94-103 (January 1986) DOI: 10.1016/0741-5214(86)90072-8 Copyright © 1986 Society for Vascular Surgery and North American Chapter, International Society for Cardiovascular Surgery Terms and Conditions

Fig. 1 Normal aortoiliac vascular anatomy. Each hypogastric artery gives rise to iliolumbar and lateral sacral arteries, which perfuse lumbar and sacral spinal canal regions. Inset, greater medullary artery originates as one of left suprarenal intercostal branches.

Fig. 2A F. Preoperative (left) and postoperative (right) aortoiliac vascular anatomy is shown for all cases. Cases 6 and 7 were combined because of their similarity. Perfused regions of native vessels are darkened. See text for details.

Fig. 3 A, Intrinsic and extrinsic (B) blood supply of spinal cord. A, In cross-sectional view shaded region is perfused by posterior spinal arteries while unshaded region is perfused by anterior spinal artery. B, Ventral medullary “feeder” vessels to anterior spinal artery are shown. Greater medullary artery is shown arising at T-10 level. Arrows indicate predominant direction of blood flow in spinal arteries.
