Anatomical Variations of Lumbar Arteries and Their Clinical Implications: A Cadaveric Study

Figure 2

The posterior aspect of a fixed abdominal aorta demonstrating four pairs of lumbar arteries and median sacral artery arising from individual stems. The lumbar arteries and median sacral artery are painted in red for clear identification. A ten-centimeter long scale is kept on the side of the specimen to indicate the size. A: first pair of lumbar arteries. B: second pair of lumbar arteries. C: third pair of lumbar arteries. D: fourth pair of lumbar arteries. E: median sacral artery. H: abdominal aorta. I: common iliac arteries.
