A study concerning morphometry of abdominal aorta branches and abdominal viscera: relations and correlation

Abstract

Research interest on abdominal aorta branches and abdominal viscera morphometry is renewed by technological evolution and development of new radiologic and clinical applications including stent grafts and chemoembolisation materials. Despite that, data on morphometry of abdominal aorta branches and abdominal viscera are lacking. To investigate this subject authors performed a morphometric study on 50 adult fresh and embalmed Caucasian cadavers and examined abdominal aorta branches’, kidney and spleen morphometry. Our results on arteries’ morphometry did not differ significantly from those of the literature; yet, we discovered significant differences between fresh and embalmed cadavers on viscera morphometry, spleen and kidneys. We also found previously unreported correlations between abdominal aorta branches’ morphometric characteristics. Even more, we identified correlations between regional arteries and viscera morphometric characteristics, proposing a new factor determining viscera development. Finally, we performed an extensive literature review so to place our results in an anatomic, embryologic and, even more, a clinical context. We believe that our results add knowledge on abdominal aorta branches and viscera morphometry and are valuable for clinical, radiological and surgical applications including visceral arteries’ aneurysms investigation and treatment, chemoembolisation procedures, stent grafts design and transplantation.
