Determinación del origen de las arterias ventrales y las bifurcaciones de la aorta abdominal e iliacas en estudios de tomografía espiral multicorte

Abstract

The anatomical-morphological study of vascular structures holds great value, in the academic sense as in its
clinical practical application; such observations can not only be made in corpses, but in image studies from living
subjects. The aim of this study was to determine the origins of arteries from abdominal aorta, and its bifurcations.
CT simulation studies from Hospital Goyeneche Radiotherapy Service patients were reviewed, in order to get
data (101 studies). It was found that the following branches get their origins in the correspondent levels most
frequently: celiac trunk in T12, superior mesenteric artery in L1, renal arteries in L1, inferior mesenteric artery
in L3, abdominal aorta bifurcation in L4, and both common iliac arteries in L5. The most constant were inferior
mesenteric artery origin and abdominal aorta bifurcation. These findings are similar to those already described
in previous studies, therefore it is a recommendation that there should be studies made in Radiology and
Radiotherapy services for evaluation of anatomical variants and morphology.
