It is imperative that gynecologists, surgeons, and radiologists know the topography of the aortic bifurcation when operating in the retroperitoneal area. Aortic-iliac atherosclerosis can also be affected by it. Data from different populations are scarce, but it shows ethnic variations. Aortic bifurcation topography in rural populations was investigated in this study. To expose the termination of the abdominal aorta, abdominal viscera, peritoneum, and fibrolipid connective tissue were removed. In addition, our study recorded the level of the vertebral bifurcation, its angle and asymmetry. These tables and bar charts present the results of data analysis using SPSS version 17.0 for Windows. In the iliac arteries, all aortae bifurcate. Bifurcations at L4 were most common. Three hundred seventy-three percent of the cases resulted in bifurcations below L4. In over 20% of the individuals studied, the topography of the aortic bifurcation differed from conventional descriptions. Radiologists and surgeons should be conscious of this to avoid inadvertently injuring arteries. These findings suggest a greater vulnerability to abdominal aortic atherosclerosis due to higher bifurcation angles and asymmetry. Atherosclerosis should be assessed preoperatively and monitored postoperatively.
