Origin of the Celiac and Superior Mesenteric Arteries in a Common Trunk - Description of a Rare Vessel Variation of the Celiacomesenteric Trunk with a Literature Review

Abstract

Summary: A variation artery was observed in a Japanese cadaver. The celiac and superior mesenteric arteries arose from a common trunk (also referred to as the celiacomesenteric trunk), but not from the abdominal aorta, respectively. From the common trunk, the common hepatic artery was distributed in the right part of the liver, and the left hepatic artery arose from the left gastric artery, which also arose from the common trunk. The left inferior phrenic artery arose from the common trunk, but the right inferior phrenic artery arose from the right middle suprarenal artery. This information regarding the branch pattern in this variation artery is useful for clinical examination and treatment.

A rare anastomosis between the common hepatic artery and the superior mesenteric artery: a case report

“…There are several classifications regarding the origin and topography of abdominal arteries [ 7 , 13 , 17 – 21 ]. The most common are various types of the celiac trunk branches [ 6 – 9 , 14 , 17 , 22 ], atypical liver vascularization [ 3 , 17 , 20 ] and differences in the territory of the mesenteric arteries [ 8 , 14 , 17 , 23 ]. The typical ‘natural’ anastomosis between the superior pancreaticoduodenal artery and the inferior pancreaticoduodenal artery forms an arterial communication named the anterior and posterior pancreaticoduodenal arcade [ 15 , 22 , 24 ].…”

“…Hirai et al [ 8 ] described a case where two trunks replaced the celiac trunk: the hepato-spleno-mesenteric trunk and the gastro-phrenic trunk. Yan et al [ 14 ] reported the celiac and superior mesenteric arteries arising with a common short trunk from the abdominal aorta. Iacob et al [ 9 ] described an absence of the celiac trunk, with the left gastric and the common hepatic arteries originating directly from the anterior wall of the abdominal aorta.…”

“…Despite having a normal or variable origin, the common hepatic artery may follow an unusual course. Yan et al [ 14 ] found the artery to have a 13% probability of originating from the superior mesenteric artery. Okada et al [ 30 ] observed the possibility of the common hepatic artery originating from the left gastric artery.…”

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

“…However, there is a very close anatomical and functional connection between the celiac trunk and the SMA, and considerable variations on their branching pattern have been observed in previous studies[1-9]. Among these variations, celiomesenteric trunk (CMT) has been considered as one of the rare types, with incidence ranging from 0.4% to 2.7%[1,4,7,8,10-15].…”

A case of celiacomesenteric trunk in combination with bilateral duplication of renal arteries and hypospadias

“…A celiacomesenteric trunk (CMT), with common origin of the celiac and superior mesenteric arteries from the aorta, is quite rare and has incidence from 0.25% -2.7% in various studies. 1,[3][4][5][6][7]11,13,15 This anatomical variation may be accompanied by some other arterial anomalies 8 . Presence of celiacomesenteric trunk may be occasionally recognized during clinical examination, particularly when using medical imaging techniques.…”
