abstract ={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.}
