Findings and procedure details
We present CT cases of celiac trunk variants,
as well as their MPR and MIP reformations.
- Hepato-spleno-gastric trunk combined with hepatic variants: the common hepatic,
left gastric and splenic arteries arise from common trunk,
as in the normal trunk anatomy; this finding can be associated with: the presence of a replaced right common hepatic artery arising from the superior mesenteric artery (Fig.
2); the presence of a left common hepatic artery arising from the left gastric artery (Fig.
3).
- Hepato-splenic trunk: the common trunk ends dividing into common hepatic and splenic arteries whereas the left gastric artery arises from the Aorta (Fig.
4).
- Hepato-gastric trunk: common hepatic and left gastric arteries origin from common trunk,
whereas the splenic artery originates from the Aorta (Fig.
5).
- Spleno-gastric trunk: origin of splenic and left gastric arteries from a common trunk,
whereas the common hepatic artery arises from the superior mesenteric artery (Fig.
6).
- Absent celiac trunk: the three main arteries arise directly from the abdominal Aorta (Fig.
7).
- Combined anatomical variants: all the previously described variants can mix together to give birth to combinations of vessel variants (Fig.
8).
