Does an aberrant right hepatic artery really influence the short- and long-term results of a pancreaticoduodenectomy for malignant disease? A matched case-controlled study.

Background: An aberrant right hepatic artery (ARHA) is a common anatomic variation. The risk associated with ARHA during pancreaticoduodenectomy (PD) continues to be debated. The aim of this study was to compare the clinical outcomes and survival after PD with ARHA against a matched cohort of patients without ARHA.
