Background:The incidence of anatomic variations of hepatic artery ranges from 20-50% in different series. Variations are especially important in the context of liver orthotopic transplantation, since, besides being an ideal opportunity for surgical anatomical study, their precise identification is crucial to the success of the procedure. Aim:To identify the anatomical variations in the hepatic arterial system in hepatic transplantation. Methods: 479 medical records of transplanted adult patients in the 13-year period were retrospectively analyzed, and collected data on hepatic arterial anatomy of the deceased donor. Results:It was identified normal hepatic arterial anatomy in 416 donors (86.84%). The other 63 patients (13.15%) showed some variation. According to the Michels classification, the most frequently observed abnormalities were: right hepatic artery branch of superior mesenteric artery (Type III, n=27, 5.63%); left hepatic artery branch of the left gastric artery (Type II, n=13, 2.71%); right hepatic artery arising from the superior mesenteric artery associated with the left hepatic artery arising from the left gastric artery (Type IV, n=4, 0.83%). Similarly, in relation to Hiatt classification, the most prevalent changes were: right hepatic accessory artery or substitute of the superior mesenteric artery (Type III, n=28, 6.05%)), followed by liver ancillary left artery or replacement of gastric artery left (Type II, n=16, 3.34. Fourteen donors (2.92%) showed no anatomical abnormalities defined in classifications, the highest frequency being hepatomesenteric trunk identified in five (01.04%). Conclusion:Detailed knowledge of the variations of hepatic arterial anatomy is of utmost importance to surgeons who perform approaches in this area, particularly in liver transplantation, since their identification and proper management are critical to the success of the procedure.

Accessory right hepatic artery branched from gastroduodenal artery

The right hepatic artery usually branches from the common hepatic artery, however, there are cases showing anatomic variations. We present 41-year-old female patient with gallbladder cancer. In this case, the accessory right hepatic artery branched from the gastroduodenal artery, passed in front of the common bile duct and fed into the anterior segment of the liver. Cholecystectomy and resection of the extrahepatic bile duct with hepaticoenterostomy were performed successfully, preserving the accessory right hepatic artery. There are few reports presenting such an extremely rare anomaly of hepatic arteries in the English literature. Additionally, we herein present a review of the English literature regarding anatomic variations of right hepatic artery.

Introdução:Variações anatômicas são pequenas diferenças morfológicas congênitas que aparecem nos diferentes sistemas orgânicos, as quais não acarretam prejuízo ou distúrbio funcional para o indivíduo. No que diz respeito aos vasos sanguíneos, alterações no desenvolvimento embriológico podem gerar duplicidade de vasos, agenesia ou ocasionar o surgimento de artérias e o desembocar de veias fora da descrição anatômica padrão. Relato de caso: Foi observada dupla variação anatômica vascular em um indivíduo durante uma dissecação de rotina no Laboratório de Anatomia do Centro Universitário São Camilo. A artéria renal principal tinha origem na parte abdominal da artéria aorta seguindo até sua entrada no hilo renal, porém, em vez de um trajeto retilíneo a partir da aorta, a mesma possuía um trajeto descendente e bem angulado. A partir da artéria renal principal surgia uma artéria polar aberrante que entrava no polo inferior do rim direito. Em um nível mais inferior, na altura da bifurcação da aorta, originava-se outra artéria polar aberrante que entrava no hilo renal, seguindo um trajeto retilíneo até o polo inferior do rim direito. A artéria hepática comum originava-se no tronco celíaco seguindo até sua entrada na porta do fígado. A artéria mesentérica superior possuía origem no tronco celíaco. A artéria hepática direita originava-se na artéria mesentérica superior. Conclusão: O estudo das variações anatômicas constitui-se tarefa árdua em virtude das inúmeras expressões diferentes que ocorrem no corpo humano, porém, o conhecimento dessas variações é de extrema valia para a clínica e o planejamento cirúrgico, garantindo a precisão e evitando complicações pós-cirúrgicas ou diagnósticos errôneos.

Variações da artéria hepática: estudo anatômico em cadáveres

Abstract: Changes in hepatic arteries are frequently found and in this study their incidence was 40%, similar to the literature. The most significant change, observed in 10% (3 cases), was the right hepatic artery with its origin in the superior mesenteric artery.
