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

Figure 1

A cadaver demonstrating the posterior abdominal wall structures of the right side of the body. In this specimen, the inferior vena cava has been dissected and folded to the left side of the body to demonstrate the structures passing posterior to it. The first and second lumbar arteries pass posterior to the right crus of the diaphragm, and the third lumbar artery passes anterior to the right crus of the diaphragm. A: right crus of the diaphragm. B: abdominal aorta. C: inferior vena cava folded onto the left side. D: psoas major muscle. E: first lumbar artery. F: second lumbar artery. G: third lumbar artery. H: fourth lumbar artery.
