Objective To describe the main anatomical variations of the celiac trunk and the
hepatic artery at their origins.Materials and Methods This was a prospective analysis of 100 consecutive computed tomography
angiography studies of the abdomen performed during a one-year period. The
findings were stratified according to classification systems devised by
Sureka et al. and Michels.Results The celiac trunk was "normal" (i.e., the hepatogastrosplenic trunk and
superior mesenteric artery originating separately from the abdominal aorta)
in 43 patients. In our sample, we identified four types of variations of the
celiac trunk. Regarding the hepatic artery, a normal anatomical pattern
(i.e., the proper hepatic artery being a continuation of the common hepatic
artery and bifurcating into the right and left hepatic arteries) was seen in
82 patients. We observed six types of variations of the hepatic artery.Conclusion We found rates of variations of the hepatic artery that are different from
those reported in the literature. Our findings underscore the need for
proper knowledge and awareness of these anatomical variations, which can
facilitate their recognition and inform decisions regarding the planning of
surgical procedures, in order to avoid iatrogenic intraoperative injuries,
which could lead to complications.
