Abstract Body :Arterial irrigation of the liver is commonly performed by a vessel hepatic originating from the celiac trunk, the common hepatic artery; the trunk too gives off the left gastric artery to the lesser curvature of the stomach and the left gastric artery splenic to the spleen. However, when emphasizing the hepatic branch of the celiac trunk, it is necessary to detail the emergence of the subsequent artery as the hepatic artery proper, which subdivides into the left branch of the proper hepatic artery - giving off the branch through the hepatic proper - and in the right branch, giving off the cystic artery to the gallbladder in a significant amount of the population (MOORE et al., 2021). The existence of accessory hepatic arteries is due to embryological factors in which, even in the presence of common hepatic vessels, there is still deficiency in vascularization or in sending adequate growth factors to the cells of the liver. This case study aims to report an anatomical variation present in the left gastric artery, which commonly gives off esophageal arterial branches. However, in addition to the aforementioned branches, a variant of this vessel was observed to produce a significant contribution to the irrigation of the liver and its surgical relevance, the accessory left hepatic artery.The existence of an anatomical variation regarding hepatic irrigation was observed, where a left hepatic artery appears as a branch of the left gastric artery after issuing its esophageal branches.The existence of accessory hepatic arteries is due to embryological factors in which, even in the presence of common hepatic vessels, there is still a deficiency in vascularization or in sending adequate growth factors to liver cells. Therefore, the instinctive generation of alternative and effective resources for visceral development is justifiable (DUTTA, S., 2010). Following Michels' classification, Class 4 was observed in the hepatic irrigation pattern of this case report, which is characterized by an accessory left hepatic artery originating from the left gastric artery. The accessory left hepatic artery originating from the left gastric artery is often located in the superior portion of the hepatogastric ligament and generally enters the left hepatic lobe through the umbilical fissure (CIROCCHI, 2020).The practical relevance of these variations becomes clear in invasive procedures, such as liver transplantation, where precise anatomical knowledge is imperative to avoid complications. Furthermore, understanding the embryological context and anatomical path of this variation not only enriches research, but also provides alternative perspectives for the clinic, highlighting the continuous need for research and updating in human anatomy.
