Variation of splanchnic arterial anatomy is frequent and may complicate pancreatic surgery, leading to life‐threatening postoperative complications. We report a case of severe hepatic dysfunction after pancreaticoduodenectomy due to accidental section of the right hepatic artery. Bedside ultrasound examination showed a reversed arterial flow in the paramedian segments of the liver. Based on intraoperative and ultrasound findings, a retrograde arterial supply of the right liver from the left hepatic artery through spontaneous anastomosis between the arteries of segment 4 and the right paramedian segments was assumed and confirmed by postoperative CT examination. © 2010 Wiley Periodicals, Inc.
