We studied the prevalence of the transpancreatic common hepatic artery (tp‐CHA) and coexisting variant anatomy. The study group comprised 788 consecutive liver transplant donor candidates who had undergone thin‐section multidetector‐row computed tomography (MDCT) studies to investigate vascular anatomy. Multiplanar reformatted (MPR) images obtained from the arterial phase were retrospectively reviewed to assess the presence/absence of the tp‐CHA. Five cases of tp‐CHA with pancreaticobiliary tumors were also included in an investigation of the presence/absence of variant hepatic arteries, celiac stenosis, and circumportal pancreas. Three of the 788 (0.38%) donor candidates had a tp‐CHA. Overall, eight tp‐CHA cases were assessed for coexisting variant anatomy. Seven of these eight cases had a hepatomesenteric trunk, six had celiac stenosis, and two had a circumportal pancreas. The prevalence of the tp‐CHA was 0.38% (approx. one in 260 in normal populations). A tp‐CHA can commonly be associated with a hepatomesenteric trunk and celiac stenosis. A circumportal pancreas can also coexist with a tp‐CHA. Clin. Anat. 31:598–604, 2018. © 2017 Wiley Periodicals, Inc.
