A Different Origin of the Right Gastro-omental Artery/Un Origen Diferente de la Arteria Gastro-omental Derecha

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.
