Abstract

PUELMA, F  and  OLAVE, E. Relationships Between of the Origin of Celiac Trunk, Mesenteric and Renal Arteries with the Vertebral Column in Chilean Individuals. Int. J. Morphol. [online]. 2010, vol.28, n.4, pp.1227-1234. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022010000400038.

At present many surgical invasive, diagnostic and therapeutic procedures require a precise knowledge of the arterial anatomy of the abdominal territory. Among these interventions the extraction of organs stands out in alive donors (renal and hepatic) and the oncological interventions, among others. Traditionally, the study of the vascularization has been carried out by means of arteriographies which require invasive procedures with injection of contrast substances and long expossue to X-rays, obtaining two-dimensional images in which the relations between the tissues and organs is difficult to analyze. The aim of the present work was to determine the anatomical characteristics of the celiac trunk, superior mesenteric, renal and inferior mesenteric arteries and the relation of origin with the vertebral column. Images of 74 patients, 40 men and 34 women, submitted to an tomography of the abdominal part of the aorta, were studied as were the characteristics and the relations of the mentioned arteries. Images used were obtained by means of multidetector computed tomography. The classic division of the celiac trunk in three branches was observed in 60,8 % of the cases, the origin related with T12 in 50 % of the men and in 52,9 % of the women, with L1 in 50 % and 47,1 %, respectively. The superior mesenteric artery originated to level of T12, L1 and L2 in 8,1 %, 78,4 % and 13,5 %, respectively. The renal arteries were double in 18,9 % of the cases. With regard to the classic descriptions we found differences that demonstrate the variability of the vascular distribution. The method is validated as a useful instance of low risk for the patient and reproducible for the researchers and clinical.
