Celiacomesenteric trunk

Abstract

The celiac trunk is the widest ventral branch of the abdominal aorta. The unusual embryological development of the ventral splanchnic arteries can lead to considerable variations. During the dissection of a 54‐year‐old male cadaver as a rare variation, a celiacomesenteric trunk was observed. The rare occurrence of this variation is stated to be 1%;–2.7%;. As in the other case, the celiac trunk and the superior mesenteric arteries arose from a common trunk at the level of L1. This case of celiacomesenteric trunk is described in detail, which can be of value in the operative procedures of the upper abdomen. Clin. Anat. 10:231–234, 1997. © 1997 Wiley‐Liss Inc.

Arterial anomalies of the celiac trunk and median arcuate ligament compression in dogs and cats assessed by computed tomography angiography

“…Branching of the CA in small animals is reported as comparable to the human—trifurcation into left gastric artery (LGA), splenic artery (SA), and common hepatic artery (CHA) . Abnormal development can lead to anatomical variation of the CA and its branches either as a bifurcated vessel—with separate origin of the LG, CHA, or SA—or a celiacomesenteric trunk (CMT) where one or all of the CA branches and the CMA share a common origin from the aorta (Figure ) . Anatomical variations of the celiac trunk and superior mesenteric artery are commonly reported in people (10.2%) with a CMT reported in 0.5%‐3.4% of patients .…”

Celiomesenteric trunk: Two variants of a rare anomaly

“…There is another report of a short CMT, 0.8 mm in length (as in the second case we have presented), but this was discovered during anatomic dissection of a cadaver. 7 The presence of a CMT has important clinical implications. A patient with this anomaly lacks the collateral protection of a dual vascular supply to the abdominal viscera.…”

A case of celiacomesenteric trunk in a Tanzanian man

“…Embryologically therefore, the occurrence of celiacomesenteric trunk can be explained by regression of the 10th root and persistence of both the 13th root and the anterior anastomosis. The diagnosis celiacomesenteric trunk has often been reported during autopsy or accidentally during angiography or abdominal computed tomography scanning [5,13]. This anomaly have been reported to be associated with clinical conditions like chronic occlusive disease, compression by abdominal aorta aneurysm [14], celiac compression syndrome [15], or rarely large gastrointestinal infarction due to thrombosis of the celiacomesenteric trunk [4].…”

“…Presence of the celiacomesenteric trunk of which its injury can lead to lethal effects to the individual however, is not common [4]. The rare occurrence of celiacomesenteric trunk variation has been stated to be between 1% and 2.7% [5]. Various anatomical variations in the coeliac trunk–hepatic arterial system and the renal arteries have also been reported in patients undergoing multidetector CT (MDCT) angiography of the abdominal aorta [6].…”
