A Different Origin of the Right Gastro-omental Artery

Abstract

SUMMARY:The gastro-omental artery is one of the branches of the common hepatic artery. Alterations in the embryonic development of the ventral splanchnic arteries can cause marked variations. A rare variant of the right gastro-omental artery was observed during dissection of a 50-year-old male cadaver. The occurrence of this variant has not been reported in the specialized literature. This case of a different origin of the gastro-omental artery is described in detail in order to provide information that may contribute to upper abdominal surgeries.

A Comparison of the Celiacomesenteric Trunk in the Caribbean with Global Prevalence Calculated by a Systematic Review

“…To add an additional layer of complexity, some authors include variants with only two main CT branches arising from the common origin in their definition of a CMT [ 14 , 36 , 47 , 60 ]. For example, Tang et al [ 47 ] defined the CMT as a “ single common trunk arising from the aorta, and the branches include the SMA and at least two major branches of the CT.” Whitely et al [ 14 ] also included variants with the SMA plus two major CT branches, defining this as an “incomplete CMT.” Yet, other authors reporting on the CMT ignore variants that include a combination of the SMA plus two CT branches [ 13 , 27 , 65 ].…”

“…Still, other authors include variants where the SMA plus one CT branch has a common origin from the aorta [ 11 , 54 , 60 ], while others do not consider these variants as CMTs [ 29 , 36 , 47 ]. For example, Kornafel et al [ 29 ] excluded a variant in which the common hepatic artery (CT territory) arose from the SMA, instead terming this a “hepato-mesenteric trunk.” Meanwhile, other authors have introduced descriptive terms such as “complete vs. incomplete” CMTs [ 14 , 33 , 68 ] that inconsistently seem to be used interchangeably with “classic vs. variant” CMTs [ 11 ].…”

“…Benjamin Lipshutz is credited with coining the term "truncus celiacomesenterica" when he described 2 cadavers with a variant where the SMA and CT took a common origin from the aorta [1]. In the subsequent decades, the CMT was documented in case reports [54][55][56][57][58][59][60][61][62][63][64][65][66] and larger population-based series [1,. ese data suggest that CMToccurs in 0.42% [37] to 2.7% [35] of unselected persons across the globe.…”
