Table 1 New definition and classification for description of celiomesenteric trunk
Definition and typeDescription
Definition
CMTWe defined the CMT as a single common trunk arising from the aorta and its branches including the SMA and at least two major branches of the celiac trunk
Type (abbreviation)
HGSM trunk (type I)Hepato-gastro-spleno-mesenteric trunk
HSM trunk + LGA (type II)Hepato-spleno-mesenteric trunk with LGA arising from the aorta
GSM trunk + CHA (type III)Gastro-spleno-mesenteric trunk with CHA arising from the aorta
HGM trunk + SA (type IV)Hepato-gastro-mesenteric trunk with SA arising from the aorta
Other (type V)Any other variation that meets the above definition of the CMT
