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.

Origem das artérias celíaca e mesentérica cranial por tronco comum em cão

“…A distância do tronco até os ramos terminais da artéria celíaca foi de 3mm. Medidas semelhantes às realizadas acima só foram feitas por ÇAVDAR et al (1997), que descreveram o tronco celíaco-mesentérico em humanos. Maiores comparações não foram possíveis, já que são espécies completamente diferentes.…”

“…Todavia, em alguns casos relatados na literatura compilada, as artérias celíaca e mesentérica cranial tiveram sua origem em um único ramo: o tronco celíaco-mesentérico. Esta variação anatômica foi relatada em 39,3% dos ovinos por LANGENFELD & PASTEA (1977); em 9,67% dos bubalinos por MACHADO et al (2000); em 6,66% dos caprinos por FERREIRA et al (2001) ÇAVDAR et al (1997).…”

Celiomesenteric trunk demonstrated by multi-detector computed tomography angiography: two cases of a rare vascular variation

“…In both cases presented in this article CMT's length was less than 1 cm. In the literature there are 2 reports of the short CMT variant, the one detected on MDCTA [16] and the other discovered during anatomic dissection of a cadaver [3]. This variant may be underdiagnosed with angiography as it quite difficult to discern a short CMT from a common origin of the SMA and the celiac trunk, as the tip of the catheter may easily transverse the common trunk and enter the orifice of one of its branches [16].…”

A Different Origin of the Right Gastro-omental Artery

“…In some cases, the trunk itself may be absent and its branches then arise from the aorta (Morettin et al, 1965;Okada et al, 1983;Vandamme & Bonte;Basar et al, 1995;Yamaka et al, 1985). In rare cases, the celiac trunk and the superior mesenteric artery can be fused to a celiacomesenteric trunk (Cavdar et al, 1997;Detroux et al, 1998;Agarwal et al, 2000). The aim of this study was to describe the rare occurring gastroomental artery variation, which can be a guide and precaution during operative procedures in the region.…”
