Abstract

Background: The hepatic artery system is an anatomically complex system with variable branching patterns, primarily determined by origin and branching. With the development and usefulness of imaging, epidemiological anatomy studies can assist in general surgery and endovascular interventions. Objectives: (1) To investigate the branching pattern of the hepatic artery on computed tomography (CT) scans, (2) To correlate the size of the hepatic artery with age, gender, and branching pattern. Materials and methods: This is a cross-sectional and retrospective study of individuals aged ≥18 years, without any diseases that affect the anatomy of the hepatic artery, who underwent contrast-enhanced CT scans of the abdominal region. We investigated the correlation between the size of the hepatic artery with age, gender, and branching pattern. Results: The mean age of the subjects was 59.2 years, with 42% females and 58% males. The most common branching pattern according to Michels was the common hepatic artery originating from the celiac artery (type 1), accounting for 94.9%. The mean diameter of the common hepatic artery was 5.3 ± 1.0 mm. The mean length of the common hepatic artery was 34.9 ± 8.4 mm. The mean diameter of the proper hepatic artery was 4.4 ± 1.0 mm. The proper hepatic artery had a 96.6% origin from the common hepatic artery, and in the remaining 3.4% cases, there was no proper hepatic artery. The length of the common hepatic artery increased with age group (p<0.05). The diameter of the common hepatic artery and proper hepatic artery were larger in males than in females, and the difference was statistically significant (p<0.05). Conclusion: Due to the increasing frequency of anatomical variations in the hepatic artery system, a clear understanding of hepatic artery anatomy is essential for both clinical and imaging physicians.
