Background/Aim Anatomic vascular abnormalities of the hepatic arteries are frequent. The aim of the study was to analyze the influence of hepatic arterial variations on postoperative morbidity and resection margin status after pancreatoduodenectomy (PD). Materials/Methods Patients who underwent PD over a 7-year period (2010-2017) were included in the study. Patients with variant hepatic arterial anatomy were matched 1:2 for age, sex, ASA score, and histology. Results A total of 232 patients underwent PD. Variant hepatic arterial anatomy was found in 35 (15.1% of the total patient population). The most common variation was an accessory right hepatic artery (8.19%) and a replaced right hepatic artery (5.60%) arising from the superior mesenteric artery. These 35 patients were compared with 70 patients with no hepatic artery variations. Postoperative surgical complications occurred in 12.1% and 26.5% (P = 0.08) and in-hospital mortality was 6% and 5.4% (P = 0.99) between patients with and without variant hepatic arteries. There was no difference in positive resection margins (R1) (18.2% vs 20.5%, P = 0.99) between the two groups. Conclusions An aberrant hepatic artery does not increase morbidity or R1 resection in patients undergoing PD.
