Purpose
Knowing the anatomical variation of the coeliac trunk (CT) and its detailed interpretation in the preoperative period is important for the prevention of iatrogenic injury during liver surgery or endovascular intervention on the coeliac trunk and its branches.
Methods
A diagnostic abdominal computed tomography angiography (CTA) was performed in a 61-year-old male patient, who was investigated for a liver cancer and chemoembolization was planned.
Results
CTA reveals that right hepatic artery (RHA) arises directly from the abdominal aorta, at the level of CT. This vessel coursing to the right hepatic lobe, functioning therefore as a replaced right hepatic artery (RRHA). Also, the left gastric artery (LGA) arises directly from the abdominal aorta. This patient successfully underwent chemoembolization from RRHA.
Conclusion
We presented a case of new anatomical variation involving the origination of RRHA and LGA from the abdominal aorta.
