Introduction: Knowing the morphology of abdominal aorta (AA) and its branches are important as
regards to diagnosis and surgical treatments. Despite that, data on morphometry of abdominal aorta
branches and abdominal viscera are lacking.
Aim: To investigate this subject authors performed a morphometric study on 80 adult fresh and
embalmed Asian cadavers and examined abdominal aorta branches to make morphometric
measurements of AA and its branches, to investigate sites of the origins of the branches and their
relationships and variations and to compare the results with literature. We believe that our results add
knowledge on abdominal aorta branches and viscera morphometry and are valuable for new radiologic
and clinical applications including stent grafts and chemoembolisation materials and surgical
applications including visceral arteries' aneurysms investigation, treatment, and transplantation
precedures.
Materials and Methods:
The study was conducted on 80 AA specimens that were obtained from human cadavers during
autopsies Guntur General Hospital from March 2020 to October 2021. These specimens of AA and
its branches were measured with a metal scale morphometrically to determine diameter of Aorta and
distances between branches
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 is more in > 40yrs age group
than age group < 40yrs. The average distance from CT-AB, CT-SMA, SMA-IMA and IMA-AB were
measured as 10.99cm, 0.76cm, 4.89cm, 3.54cm, respectively in males with average age and height was
38.26 and 158.2 respectively. Similarly, in females the average distance from CT-AB, CT-SMA, SMAIMA
and IMA-AB were measured as 10.12cm, 0.68cm, 4.69cm, 3.32cm, respectively with average age
and height was 36.24 and 145.9 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: Knowledge of morphology of AA and its branches is important in regards to the diagnosis,
surgical treatment and endovascular interventions of these vessels. We think our study will contribute
to the medical education and clinical medicine.
