Abstract
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. 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.The mean diameter of AA was studied at various levels and recorded. The study showed a decrease in caliber from above to belowIn 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.An expertiseknowledge in morphology of AA and its branches is crucial in the diagnosis, surgical treatment and endovascular interventions of these vessels.

1 The branches of the abdominal aorta may be divided into three sets: visceral, parietal, and terminal
With regard to the distance measurement, the present study shows the average distance from coeliac trunk (CT)-aortic bifurcation (AB), CT-Superior mesenteric artery (SMA), SMA-inferior mesenteric artery (IMA) and IMA-AB were measured as 10.92cm, 0.67cm, 4.9cm, 3.27cm, respectively
Summary
A good knowledge on the morphology of abdominal aorta (AA) and its branches is important in diagnosis and surgical treatment. 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. Conclusion: An expertise knowledge in morphology of AA and its branches is crucial in the diagnosis, surgical treatment and endovascular interventions of these vessels. Its terminal branches go on to supply the pelvis and lower limbs It supplies the undersurface of the diaphragm and parts of the abdominal wall. It begins at T12 and ends at L4 with its bifurcation into the common iliac arteries. 1 The branches of the abdominal aorta may be divided into three sets: visceral, parietal, and terminal
