Abstract
ABSTRACTIntroduction: The celiac trunk (CT) is one of the abdominal portion branches of the aortic artery and, together with the superior mesenteric and inferior mesenteric arteries, participates in the abdominal viscera vascularization through a series of anastomoses. Absence of CT or variation in the number of terminal branches implies in varied abdominal arteries origins, which may have implication in surgical approaches. Objective: To analyze the anatomical variations of the celiac trunk and possible associated surgical clinical implications. Methods:It is a systematic review of articles indexed in the PubMed, Lilacs, SciELO, Springerlink, Scienc Direct and Latindex databases from August to September 2017. Original articles involving the anatomical variations of the celiac trunk in humans were included. The presence/absence of the celiac trunk, the number of terminal branches and the place of origin of its branches in variant cases of the normal anatomical pattern, were considered for this study. Results: At the end of the research, 12 articles were selected, characterized by sample, anatomical structure evaluation method and main results. The normal anatomical pattern was the most prevalent in most studies (75.0%). CT was absent in 41.7% of the findings. The most prevalent anatomical variation was the presence of CT with bifurcation (66.7%). It was also observed the origin of the common and splenic hepatic arteries from the mesenteric arteries (25.0%). The presence of only one branch (16.7%) and quadrifurcation (8.33%) were other findings. Conclusion: CT variations are not uncommon findings, with different anatomic variants being reported. Thus, the importance of knowing the possible variations of this structure is emphasized, which may have implications for surgical interventions and imaging studies related to the abdominal region.
Highlights
The celiac trunk (CT) arises from the abdominal part of the aortic artery, and in its normal pattern it is possible to verify the existence of three terminal branches, the left gastric artery, which runs through the smaller curvature of the stomach, the splenic artery, which follows tortuous by the posterior superior margin of the pancreas to the spleen, and the common hepatic artery, which divides into gastroduodenal for the pancreas and duodenum vascularization, and its own hepatic artery, which will supply the liver
This trifurcation is the normal pattern of tronco celíaco (TC) present in about 89% of individuals regardless of gender, whereas anatomic variations of the bifurcation type occur in 11% of the population, and their absence is rare, affecting 0.2% of the individuals[2]
During the abdomen developing process, the primitive arteries form three arteries related to the digestive system viscera that correspond to the celiac trunk, superior mesenteric artery and inferior mesenteric artery
