[The common celiacomesenteric trunk: about one case].

The discovery of a coeliacomesenteric trunk is often fortuitous in a context of morphological or vascular exploration. About one case of this rare arterial remind us of its characteristic and different type. We emphasize the interest of not being unaware of this variation in radiological practice and vascular pathology. In our observation, the coeliacomesenteric trunk's ostium is oval with a tall axis of 14 mm; its route of 8mm is median and its arterial ending divide into hepatosplenogastric trunk and superior mesenteric trunk. It is a type I coeliacomesenteric trunk which is the most frequent type of this arterial variation in Higashi's classification.
