Celiomesenteric trunk: New classification based on multidetector computed tomography angiographic findings and probable embryological mechanisms

Figure 1 Long and short types of celiomesenteric trunk. A: A long type celiomesenteric trunk (CMT). The celiac trunk (CT) and the superior mesenteric artery (SMA) branch from the single common trunk (CMT) after originating from the aorta and continuing about 28 mm in length in this patient; B: A short type CMT. The CT and the SMA branch from the single common trunk (CMT), which continues for about 9 mm in this patient. CMT: Celiomesenteric trunk; CT: Celiac trunk; SMA: Superior mesenteric artery; LGA: Left gastric artery; CHA: Common hepatic artery; SA: Splenic artery; GDA: Gastroduodenal artery.
