Abdominal arterial branching pattern have given attention to researchers because of their significance. The variations in branching pattern of hepatic artery, supplies liver are documented by many authors. But still there are much variations present which are not classified. The aim of present study was to aid the knowledge of variation in the hepatic artery for surgeons and radiologists. For this study, scientific literature from PubMed was carried out from year 2005 to 2020 for the articles having anatomical variations of the hepatic artery in all publications. The relevant articles were also studied. Out of 2173 cases, 1500 (69.02 %) showed type I normal pattern. 37 (1.70 %) cases displayed type II: a replaced LHA from left gastric artery. Type III: a replaced RHA from SMA was observed in 158 (7.27%) cases. Type IV: replaced RHA and LHA were observed in 4 (0.18 %) cases.136 (6.25%) cases displayed type V: an accessory LHA. 7(0.32 %) of the subjects were found to have type VI: an accessory RHA. Type VII: accessory RHA and LHA. Type VIII: a replaced RHA or LHA with other hepatic artery being an accessory one were not found. Type IX: the hepatic trunk as a branch of the SMA were 14 (0.64 %). 1(0.04%) was found in type X: the CHA from the left gastric artery. Variations in hepatic arterial pattern are useful for various surgical procedures like hepatobiliary, pancreatic, gastric surgery and radiological interventions. Accidental ligation or injury to these vessels may interrupt the blood supply.
