“…Even if they originate from the same artery, their bifurcation planes and paths may be different. For example, two cases of aRHA originating from the renal artery reported by Darsan ( 27 ) in 2019 originated from the proximal end of the renal artery near the aorta and the distal end of the renal artery near the renal hilum, and their ascending paths were also different. This requires careful observation while performing an analysis of the detailed path of the artery to ensure that rapid and precise judgements are made in a limited surgical field of view.…”

Variations of the hepatic artery are very common, but they greatly increase the difficulty of surgery and the risk of complications in perihepatic surgeries such as liver transplantation, liver segmentectomy, and gastroduodenal surgery. Thus, it is important to precisely define the type of hepatic artery variant before surgery. However, there are often rare variants that cannot be defined with existing classifications. For example, the type of hepatic artery variant in the current case could not be classified with conventional classifications, and no such variation has been reported to date, involving two accessory left hepatic arteries from the common hepatic and left inferior phrenic arteries, respectively. Based on the existing 3DCT technology and the CRL classification method, which is applicable to the most common hepatic artery variants, we reviewed many rare variant types and proposed a new classification method (ex-CRL classification) for hepatic artery variations that do not fit the classic scope. The ex-CRL classification can accurately classify the vast majority of rare cases in the literature, greatly compensates for the limitations of current hepatic artery classifications, improves the generalization and understanding of rare cases, and reduces surgical complications.

“…Numerous case report studies describe the RHA traveling through the pancreatic parenchyma, traveling anterior to the common bile duct (CBD), crossing anterior to the common hepatic duct (CHD) subsequently causing a CHD stricture, or coursing anterior to the infundibulum and fundus of the gallbladder, amongst others. Similarly, variations in the source of origin include an RHA arising from the SMA, celiac trunk, aorta, left gastric artery (LGA), and right renal artery [1,[4][5][6][7][8][9][10].…”

Replaced Right Hepatic Artery Originating from the Common Hepatic Artery: A Case Report

The presence of an aberrant right hepatic artery is the most frequently encountered vascular anomaly during pancreaticoduodenectomy, and its recognition and preservation are of paramount importance to prevent ischemia of the bile duct and consequently the bilioenteric anastomosis, which can lead to anastomotic leak or dehiscence and fistula. In this case report, we describe proximal branching of the common hepatic artery (CHA) to give rise to a replaced right hepatic artery (RHA), which courses posterior to the portal vein (PV) and common bile duct (CBD) to the right lobe of the liver. The location of this replaced RHA in the hepatoduodenal ligament is consistent with the location of a replaced RHA described by the Michels classification, although with the important distinction that origin was the CHA instead of the superior mesenteric artery (SMA). From our review of the current literature, this is the first published description of such an anatomic course of the RHA.
