A rare case of replaced right hepatic artery with direct aortic origin described angiographically during trans-arterial radioembolization

Abstract: Normal hepatic arterial anatomy consists of the right hepatic artery and left hepatic artery branching from the common hepatic artery. Despite this being the most common configuration, many variations have been described. Here, we present a rare variant of hepatic arterial anatomy- a replaced right hepatic artery with direct aortic origin. Additionally, the patient was found to have a dorsal pancreatic artery originating from the replaced right hepatic artery This was angiographically identified during mapping for transarterial radioembolization for hepatocellular carcinoma. The unique anatomy in this case and the effect it had on transarterial radioembolization planning described herein demonstrates the necessity of understanding variant hepatic arterial anatomy in endovascular hepatic interventions.
