The Distance Between the Diafragm and the Origin of the Collateral Branches of the Abdominal Aorta

Abstract The Abdominal Aorta represents the terminal portion or the fourth portion of the artery, continuing the diaphragmatic portion, stretching from the aortic hiatus (at the level of the twelfth thoracic vertebra) up to the fourth lumbar vertebra, the level at which ends by bifurcation in the two common iliac artery, left and right. The survey was carried out on the computed tomography angiography’s executed on a computer tomography GE LightSpeed 16 slice CT in Medimar Imagistic Clinic located in the County Clinical Emergency Hospital “Sf. Andrei” Constanta, on healthy subjects and on the basis of sex. The distance between the origins of the collateral branches of the aorta are highly variable, causing differences in relation to sex, generally being higher in male, exceptions being due to the fact that these distances are proportional with the morphological type of the individual in question. Frequently, the maximum and minimum values of the distances have not been encountered only in one event. Like other morfometric data, the distances between the collateral arteries of the abdominal aorta firstly depend on the number of cases which it has been worked, which explains the differences between authors who are working on the same grounds and at close intervals of time, but differs on the number of cases which are working.
