AIM: To examine the morphological structure of anterior lumbar spinal region.MATERIAL and METHODS: Fifteen fresh human cadavers were studied in our forensic medicine institution. Within the first 24 hoursafter death, cadavers were subject to a routine autopsy, by which the intestines were removed and the structures adjacent to thelumbar arteries (LAs) were examined. The following characteristics of the LA were examined and recorded: diameter, number of LA,intervertebral disc, and vertebral corpus relationship, and LA anatomical variations.RESULTS: In 14 of the 15 cadavers (93.3%), the first four LAs originated from the abdominal aorta. In one (6.7%) cadaver, the fourthLA originated from the right aortic trunk together with the median sacral artery (MSA), and this was observed only in the right side.In one cadaver, the first LAs emerged as a common trunk. Twelve cadavers did not have a fifth LA. In one cadaver (6.7%), the fifthLAs emerged as in a pair, distally from the origin of the MSA. Two cadavers (13.3%) had fifth LAs that emerged from the commontrunk with the MSA and this occurred only on the right side. LAs which emerged from the right side of the abdominal aorta passedunder the inferior vena cava. Of the first four LA, the third LA had the largest vessel diameter, and the first LA had the narrowestvessel diameter. Fifth LAs had one of the narrowest vessel diameters of all LAs.CONCLUSION: We consider that anatomical study of LAs using fresh cadavers can be useful to ensure safer anterior lumbar spinalsurgeries
