          ABSTRACT

          Introduction:

          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.

          RESUMO

          Introdução:

          O tronco celíaco (TC) surge da aorta abdominal e juntamente com as artérias mesentérica superior e mesentérica inferior participa da vascularização de vísceras abdominais por meio de uma série de anastomoses. Ausência do TC ou variação no número de ramos terminais implica em origens variadas das artérias abdominais, o que pode ter implicação em abordagens cirúrgicas.

          Objetivo:

          Analisar as variações anatômicas do TC e as possíveis implicações clínico/cirúrgicas associadas.

          Métodos:

          Trata-se de uma revisão sistemática de artigos indexados nas bases de dados PubMed, Lilacs, SciELO, Springerlink, Scienc Direct e Latindex, no período de agosto a setembro de 2017. Foram incluídos artigos originais envolvendo as variações anatômicas do TC em humanos. Considerou-se para este estudo a presença/ausência do TC, o número de ramos terminais e o local de origem de seus ramos em casos variantes do padrão anatômico normal. A coleta foi realizada por dois revisores independentes.

          Resultados:

          Ao final da busca foram selecionados 12 artigos, caracterizados quanto à amostra, método para avaliar a estrutura anatômica e principais resultados. O padrão anatômico normal foi o mais prevalente na maioria dos trabalhos (75,0%). O TC foi ausente em 41,7% dos achados. A variação anatômica mais prevalente foi a presença do TC com bifurcação (66,7%). Observou-se, ainda, a origem das artérias hepática comum e esplênica a partir das artérias mesentéricas (25,0%). A presença de apenas um ramo (16,7%) e quadrifurcação (8,33%) foram outros achados presentes.

          Conclusão:

          Variações do TC não são achados incomuns, sendo relatados diferentes variantes anatômicas. Desse modo, ressalta-se a importância sobre o conhecimento das possíveis variações dessa estrutura, o que pode ter implicação em intervenções cirúrgicas e exames de imagem relacionados à região abdominal.

          Celiac axis and common hepatic artery variations in 5002 patients: systematic analysis with spiral CT and DSA.

          To identify and evaluate the spectrum and prevalence of celiac axis (CA) and common hepatic artery (CHA) variations by using spiral computed tomography (CT) and digital subtraction angiography (DSA). Institutional review board approval was obtained, and the requirement for informed patient consent was waived. The findings in 5002 patients who underwent spiral CT and DSA were retrospectively evaluated. CHA was defined as an arterial trunk containing at least one segmental hepatic artery and the gastroduodenal artery. The pattern of the aortic origin of the branches of the CA and superior mesenteric arteries was analyzed. The CHA anatomy was then investigated. Of 15 possible types of CA variation, 13 types were identified. A normal CA was noted in 4457 (89.1%) of the 5002 patients. Twelve types of CA variation were identified in 482 (9.64%) patients. In the remaining 63 (1.26%) patients, the CA anatomy was classified as ambiguous because the CHA was absent owing to separate origins of the hepatic arteries and the gastroduodenal artery (n = 55) or because the origin of the CHA could not be determined owing to persistent anastomotic channels (n = 8). Seven CHAs originating from the normal CA had a retroportal (n = 6) or transpancreatic (n = 1) course. All eight CHAs originating from the left gastric artery passed the fissure of the ligamentum venosum. The 148 CHAs originating from the superior mesenteric artery showed diverse relationships with the pancreas--being supra-, trans-, or infrapancreatic--and the superior mesenteric-portal venous axis--being pre- or retroportal. The 20 CHAs originating from the aorta had a normal suprapancreatic preportal course. Known or newly found CA and CHA variations could be systematically described in detail. The authors propose a hypothetical anatomic model for summarizing the observed CHA variations. RSNA, 2010

              Anatomical variations of hepatic arterial system, coeliac trunk and renal arteries: an analysis with multidetector CT angiography.

              The purpose of our investigation was to determine the anatomical variations in the coeliac trunk-hepatic arterial system and the renal arteries in patients who underwent multidetector CT (MDCT) angiography of the abdominal aorta for various reasons. A total of 100 patients were analysed retrospectively. The coeliac trunk, hepatic arterial system and renal arteries were analysed individually and anatomical variations were recorded. Statistical analysis of the relationship between hepatocoeliac variations and renal artery variations was performed using a chi(2) test. There was a coeliac trunk trifurcation in 89% and bifurcation in 8% of the cases. Coeliac trunk was absent in 1%, a hepatosplenomesenteric trunk was seen in 1% and a splenomesenteric trunk was present in 1%. Hepatic artery variation was present in 48% of patients. Coeliac trunk and/or hepatic arterial variation was present in 23 (39.7%) of the 58 patients with normal renal arteries, and in 27 (64.3%) of the 42 patients with accessory renal arteries. There was a statistically significant correlation between renal artery variations and coeliac trunk-hepatic arterial system variations (p = 0.015). MDCT angiography permits a correct and detailed evaluation of hepatic and renal vascular anatomy. The prevalence of variations in the coeliac trunk and/or hepatic arteries is increased in people with accessory renal arteries. For that reason, when undertaking angiographic examinations directed towards any single organ, the possibility of variations in the vascular structure of other organs should be kept in mind.
