Hepatic artery anomalies (HAA) may have an impact on surgical and oncological outcomes of patients undergoing pancreaticoduodenectomy (PD). Patients who underwent PD at our institution between July 2015 and January 2020 were retrospectively reviewed and classified into two groups: group 1, with presence of HAA, and group 2, with no HAA. A weighted logistic regression model was employed to assess the association between HAA and postoperative complications, and to assess the association between HAA and R status in patients with pancreatic cancer. 502 patients were considered for analysis, with 75 (15%) of them in group 1. They had either an accessory (n = 28, 40.8%) or replaced (n = 26, 36.6%) right hepatic artery. Most patients underwent surgery for a malignancy (n = 451; 90%); among them, vascular resection was performed in 69 cases (15%). The presence of a HAA was reported at preoperative imaging only in 4 cases (5%) and the aberrant vessel was preserved in 72% of patients. At weighted multivariable logistic regression analysis, HAA were not associated to higher odds of morbidity (odds ratio OR: 0.753, 95% confidence interval CI: 0.543-1.043) nor to R1 status in case of pancreatic cancer (OR: 1.583, 95% CI: 0.979-2.561). At our institution, the presence of HAA does not have an impact on postoperative outcomes or affects oncological clearance after PD. Hospitals', surgeons', volume and systematic review of preoperative imaging are all factors that help reduce possible adverse events.
