Background |
The aim of this study was to present an overview of variations of the hepatic artery from the origin to the segmental branching.
Methods |
Abdominal Computed Tomography performed on consecutive patients in our tertiary center between 2019 and 2020 were analyzed. Hepatic arterial branching and its relationship to the portal veins were reported.
Results |
Out of 500 imaging, 16 anatomic patterns were found for the origin of hepatic artery, with 65.6% conventional origin at celiac axis (n = 328); 10 patterns for the left hepatic artery, 23 for segment IV artery, and more than 21 for the right hepatic artery (RHA), with conventional branching in respectively 66.8%, 39.6% and in 46.4% of patients. Conventional anatomy from celiac axis to segmental branching was found in 10.4% of patients.
Conclusion |
Dedicated thin-section imaging appears to be essential for preoperative planning in liver surgery, given the high variability of arterial distribution and their surgical implications.

• | Vascular cartography of the liver must be analyzed before each surgery. |
• | Thin slice section of computed tomography allows arterial analysis. |
• | One out of ten patients has conventional arterial branching of the liver. |
