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.<\/jats:p>","DOI":"10.1590\/0100-3984.2016.0179","type":"journal-article","created":{"date-parts":[[2018,3,10]],"date-time":"2018-03-10T19:17:20Z","timestamp":1520709440000},"page":"32-36","source":"Crossref","is-referenced-by-count":15,"title":["Computed
