Pancreaticoduodenectomy (PD) is a technically demanding procedure. Anatomical variations represent an additional challenge and are present up to 45% of the population. During PD the presence of an accessory or replaced right hepatic artery can be a difficult situation to deal with when dissecting the uncinate process. We present a case of a 69 year-old female patient who underwent robot-assisted pancreaticoduodenectomy for main duct IPMN. The pre-operative CT scan showed a dominant accessory right hepatic artery with a smaller native right. The video shows the technical aspects of arterial preparation at the liver hilum and the preservation of the accessory artery.
