Abstract : Introduction: A good knowledge on the morphology of abdominal aorta (AA) and its branches is important in diagnosis and surgical treatment. The aim of this study is to make morphometric measurements of AA and its branches. Materials and Methods: The present study was conducted on 50 AA that has been removed in autopsies and were measured with calipers morphometrically to determine diameter and distances between branches. The variations of the vessels were investigated and photographed. Result: The mean diameter of AA was studied at various levels and recorded. The study showed a decrease in caliber from above to below. In both sexes, diameter of Aorta above 40yrs age group is more than age group less than 40yrs. The average distance from CT-AB, CT-SMA, SMA-IMA and IMA-AB were measured as 10.92cm, 0.67cm, 4.9cm, 3.27cm, respectively.. Numerous variations were observed during the study which include absence of renal artery, origin of renal arteries one above the other, 3pairs of lumbar arteries etc. Conclusion: An expertise knowledge in morphology of AA and its branches is crucial in the diagnosis, surgical treatment and endovascular interventions of these vessels.
