Impact of Right Hepatic Artery Anomalies on Pancreatoduodenectomy Outcomes

In periampullary cancer patients undergoing pancreatoduodenectomy, anomalies in the right hepatic artery (RHA) anatomy, including accessory or replaced RHAs, were observed in 16.3% of cases. However, when comparing outcomes with a propensity score-matched analysis, the presence of these anomalies did not significantly impact perioperative complications or histopathological findings. High-volume centers performing pancreatoduodenectomy can manage cases with anomalous RHA without a notable increase in adverse outcomes.
